The Evolution of the International System in International Relations
Introduction to the International System
The international system was shaped by the transition from feudal loyalties to territorial sovereignty, resulting in constant tensions and power struggles.
Various practices and norms developed to regulate common affairs among states, seeking to maintain a balance of power and minimize the chaos of perpetual warfare.
Development of Diplomatic Practices
Origins: The roots of modern diplomacy are found in the $15^{th}$ century Italian city-states, such as Venice and Milan, which pioneered the use of permanent resident ambassadors.
After major conflicts, European states established the tradition of holding peace congresses to reach settlements and define protocols for future interactions.
As states gained independence from the central authorities of the Pope and the Holy Roman Emperor, secular diplomacy became the primary vehicle for pursuing national interests.
Diplomatic correspondence served multiple functions, including intelligence gathering, maintaining open communication channels, and negotiating complex military alliances.
Expansion of Diplomatic Practices
The formalization of the international system led to the establishment of specific legal protections:
Extraterritoriality: The legal fiction that an embassy's grounds remain the territory of the sending state.
Diplomatic Immunity: Protections afforded to diplomats to ensure they could represent their sovereign without fear of local entanglement or arrest.
Inviolability of Missions: The guarantee that embassy premises and communications are protected from interference by the host state.
The Peace of Westphalia in $1648$ codified these principles of sovereignty and non-interference, marking the birth of the modern state system.
By the mid-$17^{th}$ century, these protocols were adopted by a growing list of powers, including France, Spain, Austria, England, Russia, Poland, Denmark, and Sweden.
Nature of Warfare and European Identity
Despite the rise of diplomacy, warfare remained a central feature of the system, though it was governed by emerging codes of conduct that prevented total destruction.
A shared sense of European identity developed, where states viewed themselves as part of a common civilization with shared diplomatic and military traditions.
This "society of states" emphasized that even during war, certain legal and moral constraints should be observed.
Transformation of the State
The early modern state was primarily a "fiscal-military" entity, designed to extract resources through taxation to fund increasingly expensive standing armies.
By the end of the $18^{th}$ century, the state underwent a profound transformation into the nation-state:
A nation is characterized as a community of people sharing a common language, history, and social practices.
The French Revolution in $1789$ shifted the source of sovereignty from the individual monarch to the nation as a whole.
This evolution changed the nature of international relations, as states began to fight wars on behalf of national ideologies rather than dynastic interests.
