1. Sources of Studying History
History studies past human activities via sources.
Two broad categories of sources:
Literary sources
Archaeological sources
Local literary sources: Deepawamsa; Mahawamsa; other Pali/Sanskrit/Sinhala texts; cross-reference with Vinaya Attakatha, Uttara Vihara Attakatha, Sehala Attakatha.
Foreign literary sources: works by foreigners who visited or wrote about Sri Lanka; indicators of credibility include time of writing, author, author’s objectives, and method of obtaining facts.
Local vs foreign literary sources: Local include Deepawamsa, Mahawamsa; Foreign include Fa-Hsien, Iban Batuta, Ribeiro, Baldaeus, Knox; Wansattappakasini as Mahawamsa commentary.
Epigraphic and archaeological sources: epigraphy (Sellipi/Shilalipi) on rocks, copper/golden/wood/tiles, cave inscriptions; classification by medium is important (rock inscriptions, cave inscriptions, pillar inscriptions, slab inscriptions, seat inscriptions).
Coins and numismatics: first coins in Sri Lanka from Anuradhapura era; types include Kahapana, Purana, Dharana; local mints and foreign coins (Roman, Chinese, Indian) found in Sri Lanka; Numismatics as a key source for economy and trade.
Ancient ruins and artefacts: stupa, tanks, stone pillars, inscriptions; antiquities housed in museums; role in understanding technology, environment, and urban planning.
Important caution: historical sources are past reports and may reflect authors’ biases; use cross-verification across sources.
Tables and figures summarize: local literary sources (Table 1.1); foreign sources (Table 1.2); epigraphy media (Table 1.4); authors of epigraphy (Table 1.3).
1.2 Importance of Learning History
History builds critical thinking, social understanding, identity, reconciliation, and appreciation of other cultures.
Learning history develops a critical sense, enabling problem-solving and understanding of current societal issues.
It connects past and present through foundational principles.
1.3 Protecting Archaeological Sources
Archaeological sites are vulnerable to modern development; protecting monuments and inscriptions is a civic duty.
Marks and symbols on rocks (sun, moon, palmyra fan, animals) often denote ancient borders or communication.
Vandalism and extraction of artefacts are punishable by law; students are urged to contribute to preservation.
2. Ancient Settlements
Sri Lanka’s human habitation timeline extends to around 125{,}000 years ago (Stone Age survivals).
Homo sapiens expanded across diverse environmental zones, resulting in cultural variations.
Environment and climate influenced subsistence strategies and tool technologies.
2.1 Settlements in the Pre-historic Era (Stone Age)
Stone Age evidence found across multiple zones: Semi-arid, Lowland dry, Lowland intermediate dry, Wet Zone, Mountainous dry, Arid Zone.
Stone tools (geometric micro tools) are small, often 4–5 cm, made from alabaster or Kahanda; used for hunting, cutting, digging.
Key prehistoric sites and evidence: Pahiyangala (Bulathsinhala, Kalutara) with cave habitation; Belilena (Kithulgala); Pothana and Aligala (Sigiriya); Rathnapura gem-mines; Iranamadu Formation gravel layers indicate Pleistocene-age deposits.
Expansion around tanks and water sources linked to distribution of water and resources; evidence of nomadic to semi-settled lifestyles.
Evidence of burial practices and skeletons in caves (e.g., Belilena; Pahiyangala; Batadomba Lena, Kuruwita).
Physical anthropology: average male stature ~174\,cm; female ~166\,cm; brain volumes: male ~1600\,cm^3; female ~920\,cm^3; lifespan about 35-40\,years.
Diet: meat from gaur, buffalo, wild boar, deer; fish from freshwater pools; plant foods such as wild breadfruit and wild plantains; seeds like Kithul; seeds such as Gonala and Katuala; baked foods evidence; snails and oysters in coastal and wet zones.
Technology and knowledge: early stone tool technology; evidence for shell beads and simplistic bead-working; limited understanding of metal use (later in proto-historic era).
Life style: nomadic groups of 15–25 people per camp; sometimes 50; camps of 120–150 m² in large sites; burial and ritual practices such as red ochre painting.
Burial practices sometimes involved exhumation for ritual re-purposing; graveyards with skeletons found in specific caves.
2.2 Settlements in Proto-historic Era
Transitional period between Prehistoric and Historic eras; introduction of iron tools marks proto-historic phase.
Clay urn burials and clay tub burials reflect new funerary practices; some burials involve cremation before deposition in urns or boats.
Origin of permanent settlements; domestic architecture evidenced by excavated houses (e.g., Udaranchamadama, Rathnapura district): rectangular houses with wattle-and-daub walls and thatched roofs; floors laid in mud with wooden doors.
Pottery and bead-making demonstrate advanced craft skills (pottery wheel, beads from beadsmiths, ochre decoration, etc.).
Iron technology appears, enabling clearing of jungles, ploughing, and everyday tasks; painted clay pottery shows high technical skill.
Settlement expansion around small tanks (Vapigama, Sumanavapigama, Hundirivapigama, Kadahavapigama) – evidence of centralized tank systems around villages; tank networks (Ellangawa) developed to distribute water and increase arable land.
Parumaka and Gamika (Gamikas) emerge as village-level leaders; Parumakas control tank systems and taxes; early decentralized rule; women Parumakalu mentioned in inscriptions.
Evidence of social organization evolving toward centralized power; tank network leads to political consolidation and the emergence of a kingly class.
2.3 Settlements in Early Historic Era
450 B.C. to 300 A.D.: expansion of small village tanks becomes a key index of settlement growth; tanks provided irrigation and supported agriculture; the Anuradhapura era marks early centralized urbanization.
Causes of expansion: development of tank networks to manage water for agriculture; ability to control floods and store water; development of urban centers around tanks.
Construction and layout: villages around tanks with edges limited by jungle belts; provincial administration emerges with ministers and officials to govern districts.
Geography and hydrology influenced urban development across the island; dry zone settlements expanded outward from river valleys as a strategy against floods.
3. Evolution of Political Power in Sri Lanka
Evolution from decentralized chieftainship to centralized statehood; many kings and queens ruled across different periods.
Foundational idea: Jana-sammatha (general will) and the concept of the state arise as power consolidates.
Pre-state era (3.1): no single ruler; power held by Parumakas and Gamikas governing villages; Parumakas could offer caves to Buddhist monks and collect taxes; decentralized ruling described as the origin of state-building.
Pancha Kakudha Bhanda: five insignia used during coronations (Walvidunava, Mirivedi Sangala, Magul Kaduva, Sesatha, Nalal Patiya) and Devanampiya title reflecting Ashokan influence.
Growth of kingship: centralization of power starts with Dutugemunu; Devanampiya Tissa’s era fosters Bodhisattva imagery; centralization accelerates under Vasabha and subsequent rulers; centralization is linked to control of trade, irrigation, and religious symbolism.
Key rulers and milestones:
Dutugemunu: unites the country; centralizes power; builds Ruwanweli Seya; consolidates Parumaka support; emphasizes Buddhism.
Vasabha: initiates provincial administration; builds large reservoirs (sixteen tanks); expands Buddhist restoration.
Vijayabahu I: moves capital to Polonnaruwa; strengthens independence; suppresses Chola influence; fosters eastern trade; enhances international relations.
Concept of the State (3.2): central authority as Maha Raja; a structured administration including ministers, treasurers, architechs, soldiers, etc.; development of a centralized governance framework enabling state functions (security, economy, and culture).
Great Kings Who Ruled This Country (3.3): explores contributions of Dutugemunu, Vasabha, Vijayabahu I, and others; emphasizes state-building through centralization, economic development, and religious patronage.
Growth towards a unified state is propelled by trade interests and external relations (India, Asia, and later the West).
4. The Ancient Society of Sri Lanka
Social structure and governance: three main institutions – legislature, executive, judiciary – functioning under a monarchic framework; Ekthensamiya (king’s court) and Wathhimiyan wadala (king’s decree) demonstrate governance in ninth-century contexts.
Village governance: Gamikas (village chiefs) and Parumakas (regional rulers) coordinate tank networks and taxes; Dasa Gam Eththan as a collective council of ten villages; Dasagam Ettan (heads of ten villages) demonstrates administrative decentralization.
Temples and Devalas: management by Maha Nayaka and Anunayaka Theros; Dalada Maligawa governance via Diya Wadana Nilame (palace officers involved in temple management).
Law and tradition: law instruments and judiciary documented in inscriptions; examples include land grants with Sabhava (council) involvement; Mahale Kasba (general secretary) and other legal roles described.
Economic and social organization: land ownership by the king; land categories for palace, aristocrats, temples, Devalas; Rajakariya (people’s service to the king); a largely rural society with caste-based occupations; social cohesion through mutual obligations and religious oversight.
Religion and education: Buddhism dominant since Arahath Mahinda’s arrival; monasteries and Pannasala for monks; education delivered by monks and temple scholars; literacy and poetry flourished under royal patronage (Kotik era); diverse religious groups (Hindu, Nestorian Christians, Arabs) interacted with Sri Lanka through trade and cultural exchange.
Ethnic coexistence: Tamils and Arabs and other communities lived alongside Sinhalese; Tamil mercenaries (Agampadi Senawa) and South Indian traders active; cross-cultural exchange evident in inscriptions and urban life.
Social values: respect for women; some women ruled as rulers and Parumakalu; social roles and occupations documented in inscriptions; a sophisticated cultural and artistic landscape (artists, dancers, poets, sculptors).
Education, literature, and arts: evolution of Sinhala, Pali, Sanskrit texts; Parakumbha period as a literary flowering era; Sigiriya graffiti as a glimpse into medieval aesthetic culture; the Gampola and Kotte periods as centers of literary production.
5. The Ancient Science and Technology in Sri Lanka
Science and technology are framed as applying fundamental natural principles to practical tasks.
Early science (5.1) shows awareness of gravity and physics; examples include Stone Age tools (symmetrical, pressure-slating techniques) and early engineering principles.
Proto-historic and post-Stone Age examples demonstrate applied physics and practical technology: tomb engineering (Clay Tub Burials), house foundations (Udaranchamadama 1129 B.C.), and clay-bead technology.
Clay potmaking (Sakaporuwa, potter’s wheel) indicates advanced pottery techniques; blacksmiths (“Kabara”/Kammara) and other artisans (coppersmiths, tin-smiths) documented in inscriptions; bead and gem industries reflect sophisticated jewelry making.
Engineering and water management (5.2 Water Management): tanks, canals, and sluices (Soruwa, Diyaketa Pahana) designed to control water flow and distribute irrigation; Sigiriya water park as a model of architectural water engineering and symmetry; Ralapanawa and flood-control measures (layered tank bunds and water distribution).
Sigiriya and urban planning: Sigiriya’s city plan and park design reflect sophisticated urban planning and hydraulic engineering; fountains and water distribution operate via gravity and pressure dynamics.
Architecture and construction techniques: Jethawanaramaya, Abhayagiriya, and Ruwanweli Seya exemplify complex multi-storey temple architecture; lightning protection via Vajra chumbata (lightning conductor) on Ruwanweli Seya; foundation-building techniques echo modern concrete methods through layered materials and reinforcement.
Medicine and hygiene: ancient hospitals (Vejjasa) and maternity wards; Alahana Pirivena hospital (Polonnaruwa) webbed with surgical instruments; ancient medical practitioners and medical literature documenting indigenous healing traditions.
Local rituals and indigenous knowledge: Kirimadu Shantikarmaya and Devala shrines; Poojas (Kempahan) to ensure crop protection; indigenous knowledge systems in measurement, weights, and timekeeping (Varshaya, Purapakshaya, Awapakshaya; Duruthu, Navam, Medin months).
Measurement systems (5.2.4).
Space measurements: Laha, Pela, Kuruni, Amunu, Karisa cycles; rough equivalences given by traditional units (Laha 40 = Pela 1; Pela 12 = Kuruni 12; Kuruni 4? = Amunu 1; Amunu 1 = Karisa 0.25).
Weight: system of weights like Gunja, Masaka, Aka, Dharana, Swarna, Pala; commercial standardization ensured by law.
Time: lunar-based year divisions; Purapakshaya and Awapakshaya; months named Duruthu, Navam, Medin; Avurudu derived from Havurudu/Havajara.
Dedigama Suthighara lamp (Dedigama Elephant Lamp): bronze lamp with a reservoir in the elephant’s belly; oil moves by gravity to the lamp as oil level decreases – an early demonstration of static hydraulics.
Key takeaway: ancient Sri Lankans demonstrated sophisticated understanding of physics, hydraulics, metallurgy, and architecture, oftentimes centuries ahead of contemporary developments elsewhere.
6. Historical Knowledge and Its Practical Application
Defines “historical knowledge” as culturally embedded knowledge that survives in memory, inscriptions, and artefacts.
Six concepts highlighted for students to develop historical consciousness: ancient social organization, law and tradition, finance and exchange, protecting the environment, representation of women, and local food.
Emphasizes practical applications: learning from past administrative systems, legal frameworks, environmental stewardship, and social organization to build a resilient contemporary society.
7. Decline of Ancient Cities in the Dry Zone and Origin of New Kingdoms in the South-West
Two eras of urbanization: First Urbanization (Anuradhapura, Magama) and Second Urbanization (South-Eastern coastal kingdoms like Yapahuwa, Dambadeniya, Kurunegala, Gampola, Kotte).
7.1 Background of Urban Life: Early urbanization associated with surplus production (Athirikthaya) and strategic urban planning around water-management infrastructure.
7.2 The First Urbanization: Development of central capitals around tank systems; trade-driven wealth and the emergence of city centers; shifting capitals in response to trade networks.
7.3 The Second Urbanization: After Polonnaruwa’s decline, new centers emerged (Dambadeniya, Yapahuwa, Kurunegala, Gampola, Kotte); social change, literature revival, and new trade networks; Jaffna kingdom and Nayakkar dynasty formation occur in later phases.
7.4 Economic Style: Wet zone kingdoms rely more on rainwater and agriculture; cinnamon and other exports become key commercial crops; foreign trade influence grows; urban centers grow around harbours and markets.
7.5 Cultural flowering: religious and literary renaissance during these transitions; multiple languages and literatures (Sinhala, Pali, Sanskrit) flourish; printing and translation become catalysts in later periods.
8. Kandyan Kingdom (Udarata Rajadhaniya)
The last independent Sri Lankan kingdom (up to 1815); capital at Kandy, fortified and well-protected by the Mahaweli river and surrounding ghats (Balana, Hunnasgiriya).
Founding and expansion: Senasammatha Vikramabahu (founder); Jayaweera Bandara; Karaliyadde Bandara; Rajasinghe I; subsequent Nayakkar dynasty (Sri Vijaya Rajasinghe, Keerthi Sri Rajasinghe, Rajadhirajasinghe, Sri Vickrama Rajasinghe).
Administrative structure: king at the top; Adikarams (Maha Adikaram, Devana Adikaram); Maha Vasala (palace service); Rata Wasama (provincial ruling); Dasavamsa-level administration; temple administration through Devalas and Sanga; the Karava, Vannar groups; social classes (Kudeen, Vanquished groups, etc.).
Economics and society: agriculture-dominated; Jak (home gardens) and cash crops; iron and steel industries; nitre production; rural labor obligations (Rajakariya); a largely rural but increasingly trade-oriented economy with cinnamon and other commodities.
Religion and culture: Buddhism re-emphasized; Upasampada revived by Burmese assistance; Devalas and multiple religious centers; cultural revival and literature flourished under Nayakkar rulers; the royal court and temple complex play central roles in society.
Foreign relations and conflict: long-standing clashes with Portuguese, Dutch, and later English; King Rajasinghe II fosters Dutch alliance against Portuguese; Dutch-Kandyan covenants shape political geography; final cession of coastal territories in 1766 after protracted conflicts.
End of the Kandyan Kingdom: English intervention culminates in 1815 with the Udarata Accord; Kandyan sovereignty ends and Sri Lanka enters colonial era.
9 Renaissance (Europe) and Its Global Impact
Definition: Renaissance (14th–16th centuries) as rebirth of classical Greek and Roman culture; transition from the medieval world to early modern Europe.
Key drivers:
Fall of Constantinople (1453) pushing scholars to Western Europe with Greek/Roman texts.
Growth of trade and rise of a wealthy mercantile class (Venice, Genoa, Medici in Florence) supporting arts and learning.
Intellectual revival beyond theology (humanism); invention of the printing press by Gutenberg (1454) spreading knowledge.
Critique of Church authority and religious reform movements (Luther, Erasmus, Hus, etc.).
Transformations across sectors:
Arts and architecture: shift to human-centered and secular themes; works of Leonardo da Vinci, Michelangelo, Raphael; architecture embracing classical forms.
Science: heliocentric ideas (Copernicus); law of gravitation (Newton); telescope (Galileo); empirical method and experiments (Kepler, Galileo).
Medicine: advances in anatomy and physiology; Harvey’s circulation model; pharmacology via Paracelsus; breakthroughs in medical practice.
Printing and language: Latin and Greek revived; vernacular literature flourished; translations of classical works.
Economic and political: emergence of nation-states; growth of banking, capitalism, and new trade networks; global exploration by Portugal, Spain, later the Dutch and British.
Sri Lankan impact (9.2): Renaissance ideas reached Sri Lanka through Portuguese, Dutch, and British contact; introduced Western education systems, printing, architecture, literature, and new religious and cultural dynamics; colonial governance reconfigured political and social structures.
10 Sri Lanka and the Western World (Arrival of Europeans)
Three principal routes to Asia pre-1500s: Silk Route via Constantinople; Mediterranean route via Egypt; Persian Gulf route to Western India.
Portuguese arrival (early 16th century): driven by trade (spices such as cinnamon); aim to break Muslim monopoly on Asia trade; maritime capabilities enabled rapid expansion along coastlines; initial contact with Kotte; Vijayabahu VI era fractured by Vijaya Kollaya (1521) enabling easier Portuguese penetration.
Vantage points and early events:
1505: Francisco de Almeida appointed viceroy; Portuguese use political divisions in Sri Lanka to expand influence.
Vijayabahu VI’s death leads to division of Kotte; Mayadunne (Seethawaka) and Rayigama (Ruhuna) become centers opposing Portuguese expansion.
Portuguese tactical interventions, marriages, and diplomacy with Kotte, Seethawaka, and later Kandyan kingdom.
Conquests and conflicts:
Colombo and coastal forts become focal points; Danthure and Balana battles illustrate early military engagements; Danthure (1594) a major defeat for the Portuguese; Balana (1602) a decisive Kandyan victory.
Gannoruwa (1638) marks a turning point; Portuguese suffer notable defeats; Rajasinghe II aligns with the Dutch to expel the Portuguese, a policy that permanently alters power dynamics.
Dutch intervention and colonial shift:
1602 onward: Dutch East India Company (VOC) becomes a major force; aims include monopoly of cinnamon trade and control over coastal forts; terms of alliance with Kandyan kings; various treaties and coercive actions shape the maritime balance of power.
The 1638 Batticaloa and subsequent campaigns lead to Dutch dominance of coastal fortresses; Kandyan kings engage in periodic resistance and negotiated treaties.
1766 Peace Treaty reduces Kandyan influence but acknowledges Dutch gains; Dutch consolidate coastal power; the Kandyan kingdom’s sovereignty gradually eroded.
Jaffna and other kingdoms: Jaffna kingdom under Arya Chakravarthi; early contact with Portuguese leads to conflict, shifting loyalties, and eventual Dutch interference.
Enduring outcomes:
The Western powers (Portuguese, Dutch, English) reshape Sri Lanka’s political, economic, and cultural landscape.
European contact accelerates modernization, legal reform, education, and economic integration into global networks.
Key Thematic Connections and Implications
Synthesis of sources: Literary and archaeological sources complement one another; cross-checks with inscriptions and artefacts validate historical timelines.
Water management as driving force: Across Stone Age, Proto-historic, and Historic eras, water storage and management (tanks, canals, sluices) underpin agricultural expansion, urban growth, and state formation.
Decentralization to centralization: Early village leadership (Gamikas, Parumakas) evolves into centralized kingship; the process of centralization is closely tied to trade, irrigation, religion, and urbanization.
Trade as engine of state power: Control of harbours and river systems, plus international relations (India, China, Arabia) shapes political legitimacy and economic strength.
Religion and statecraft: Buddhist institutions and Devalas anchor political power and legitimation; rulers promote religious infrastructure as a means to stabilize and unite diverse communities.
Ethnic and cultural pluralism: Sri Lanka’s ancient society exhibits extensive interaction with Tamils, Arabs, Greeks, Persians, and Southeast Asian peoples; mutual exchange shapes language, religion, and governance.
Renaissance and colonial transformations: Europe’s cultural and scientific revolutions converge with Sri Lanka’s own dynastic shifts, leading to profound changes in governance, law, education, and global integration.
