Study Notes on the Tang Empire

The Tang Empire (618-907 CE) emerged during a significant historical intersection with the rise of Islam.
It represented a powerful center of state influence and wealth, dominating the east while Islam expanded out of Arabia into Afro-Eurasia.
Both entities competed for power and influence across Central Asia, fostering shared cultural exchanges and mobile populations between them.

China became a key hub for East Asian integration, actively receiving and disseminating foreign influences.
Notable impacts included:
- Cosmopolitan culture: Buddhism, medicine, and mathematics from India enriched urban centers.
- Chang'an and Luoyang: Major cities with diverse populations including:
- Buddhist monks from Bactria
- Greeks, Armenians, and Jews from Constantinople
- Muslim envoys from Samarkand and Persia
- Tributary missions from Annam (Vietnam)
- Nomadic leaders from the Siberian plains
- Officials and students from Korea
- Monastic visitors from Japan
- Idea diffusion: Daoism and Buddhism traveled eastward to Korea and Japan, influencing local statecraft based on Confucian models.

The Tang dynasty re-expanded Chinese boundaries and reclaimed influence over East and Central Asia after a period of fragmentation following the Han dynasty.
The dynasty's rise was precipitated by:
- Li Yuan's (the eventual Emperor Gaozu) revolt against famine and instability due to flooding of the Yellow River.
- The establishment of a strong central government marked by a doubling of provinces and government offices by 624 CE.
- The transition of power from Li Yuan to his son, Li Shimin, in 627 CE after Gaozu's abdication.

Tang armies were well-trained, comprising aristocratic cavalry and peasant soldiers:
- Cavalry strengths: Engaged in conflicts against nomadic groups, boasting around 700,000 horses at height.
- Peasant soldiers: Estimated between 1-2 million providing manpower in defense and public projects.
- Nomadic alliances: Relied on Inner Eurasian nomadic soldiers, notably the Uighurs by 750 CE, who exhibited sophisticated fighting capabilities.
At its zenith, the Tang controlled over 4 million square miles, comparable to the Islamic world of that era.
Economic prosperity was aided by fertile areas in southern China; tax systems managed under an influx of agricultural labor from about 10 million families.

The Tang dynasty modeled many advancements after the Han while innovating administrative systems unique to their context:
- Capital city: Chang'an, population of ~1 million, functioned as a fortified urban space and cultural melting pot.
- Civil service examinations: Established a rigorous testing process for government officials, predominantly based on Confucian texts, with avenues for Daoist classics as well.
- Educational accessibility: Increased opportunities for southern commoners to rise through merit, despite the closed nature of the system to certain groups.

Wu Zhao, Empress Wu, became a rare female figure of political power during the Tang, utilizing examinations to strengthen her court influence.
- She began as a favorite concubine and maneuvered into power through court intrigues and familial connections, eventually declaring herself empress (684-705 CE).
- Promoted Buddhism, established temples, and had scholarly work done to elevate women's roles in history.

Eunuchs became integral power brokers within the Tang by the late eighth century.
Their significance increased dramatically under Emperor Xianzong, who structured their careers akin to civil service.
By 838 CE, the balance of power shifted unfavorably toward eunuchs, contributing to state instability as their political influence grew.

Tang prosperity was characterized by a robust economy which included an advanced agricultural production system and dynamic markets in urban centers.
The agricultural advancements were initiated during the Sui and bolstered by:
- The Grand Canal linking northern and southern China, facilitating trade and resource distribution.
- A flourishing handicrafts industry yielding brocades, silks, porcelains, and an intricate network of artisan workshops.

Introduction of new rice varieties, particularly drought-resistant Champa rice from central Vietnam, allowed for more intensive cultivation and multiple harvest cycles.
Hydraulic engineering led to canal systems and irrigation, improving agricultural yields significantly.

The Tang played a pivotal role in facilitating trade along the Silk Roads, adapting to changing geopolitical landscapes by establishing maritime routes as alternatives.
Chinese luxury goods gained prominence in regional and international markets, solidifying China's trading relations across Asia and beyond.

Tang policy allowed various religions (Buddhism, Nestorian Christianity, Zoroastrianism, and Islam) to flourish.
Buddhism thrived particularly under state support but faced backlash from Confucian scholars who later initiated anti-Buddhist campaigns, culminating in the Wuzong persecution in the 840s.
Following suppression, Chinese cultural ideals and Confucian teachings experienced a renaissance as the state restored orthodox values.

The downfall in the late ninth century stemmed mainly from economic strife rather than religious dissent, leading to widespread peasant revolts.
Power struggles involving eunuchs and external pressure from rising Muslim powers and regional invasions intensified the fragmentation.
By the tenth century, China had splintered into regional states, transitioning towards the Song dynasty, which failed to unify the former Tang territories, leading to an era of decentralization.
