Development of International Relations


The development of International Relations (IR) as a subject of study and practice has been formed by various historical events, power shifts, and changing global dynamics. The development of IR can be understood through several key phases:

1. Pre-Westphalian Era (Before 1648)

In pre- Westphalian era of 17th century, the concept of international relations did not exist like as it exist in today. In that period, relations between political entities were largely governed and shaped by feudal, religious, and dynastic ties. But there are several instances like the interactions between the various city-states of ancient Greece, the diplomatic relations in the Roman Empire, and the power struggles between medieval European kingdoms were early reflections of international relations.

2. Westphalian System (1648 – 19th Century)

The Thirty Years’ War(1618-1648) in Europe was ended with the signing of The Peace of Westphalia, which is known as the beginning of the modern state system. The treaty established the important concept of state sovereignty, that states have their supreme authority over their own territories both in domestic and international affairs without any kind of external interference.

According to the Westphalian system, the nation-state are the primary actor in international relations. The era is the beginning of the importance of state power, the establishment of permanent diplomatic missions, and the development of the concept of international law.

3. 19th Century and the Concert of Europe (1815 – 1914)

After the Napoleonic Wars, the major European powers like – Britain, Russia, Prussia, Austria, and later France established a system of regular meetings and consultations to maintain the balance of power in Europe to prevent major conflicts. This period is known as the Concert of Europe.

The 19th century was the century of balance of power politics, colonial expansion, and the rise of nationalism. International relations in that time were mainly Eurocentric, because European powers dominating the global politics of that time.

4. Interwar Period and the Birth of IR as a Discipline (1919 – 1939)

After the devastating effect of World War I, states are rethinking about the international relations. Important focus of each state was to preventing future conflicts that time . The League of Nations was established in Jan 10, 1920 as the first international organization with the aim to maintain peace and security through out the world, although it was later failed to prevent World War II.

Birth of IR as a Discipline: The this period, International Relations developed as an academic discipline. The first IR department was established at the University of Aberystwyth in Wales in 1919.

This period was witnessed the clash between idealism and realism. where idealism emphasized international cooperation and peace, realism focused on power politics and national interests.

5. Cold War Era -The Era of Bipolarity(1945 – 1991)

After World War II, the global order was dominated by the Cold War, the ideological battle between the United States and the Soviet Union which lead to a bipolar international system. The ideological battle between capitalism and communism, as well as the emerging threat of nuclear war.

In this era of bipolarity, Realism became the dominant theory in IR. Scholars like Hans Morgenthau emphasizing the importance of power and national interest and other theories like liberalism (which focused on institutions and cooperation) and constructivism (which examined the role of ideas and identities) also gained traction.

Global Institutions like The United Nations , NATO, the International Monetary Fund and the World Bank were established to promote global cooperation and prevent conflicts. However, the Cold War saw numerous proxy wars, arms races, and competition for influence in the developing world such as The Cuban Missile Crisis (1962), the Vietnam War, the Helsinki Accords (1975), and the arms control treaties like the Strategic Arms Limitation Talks (SALT) are notable events of this period.

6. Post-Cold War Era (1991 – Present)

With the collapse of the Soviet Union in 1991, the United States emerged as the only one superpower, which is popularly known as a “unipolar world order.” This period saw an expansion and development of democracy, globalization, and liberalism.

The new challenges arises after the post-Cold War period were ethnic conflicts, humanitarian crises, terrorism, and the rise of non-state actors. The 9/11 attacks in 2001 also highlighted a great threat of international terrorism.

But In recent years, there is e shift from unipolarity to multipolarity with the rise of China, India, Australia and other emerging powers challenging U.S. dominance that created competitive and diplomatic relation among great powers.

In the post-Cold War period, various new theories arises with greater emphasis on constructivism, critical theories, feminism, and post-colonialism that challenge traditional state-centric approaches of International Relations.

7. Contemporary Challenges and Future Directions

The contemporary world is based on Globalization and Interdependence. The world has increasing interconnectedness through trade, communication, and technology, making international cooperation an essential for addressing global challenges like climate change, pandemics, terrorism and economic instability.

The revival of Russia and the rise of China have led to renewed great power competition, that raise a concerns about the future stability in the international system. Global governance institutions like the UN, WTO, and WHO and Non-state actors like terrorist organizations, multinational corporations, and international NGOs, play an increasingly important role in global affairs and changing international landscape.

Nature of International Relations

states are the primary actors of IR:

States are the key actors of International Relations and International relations is primarily a process of interactions among nations.

Conflicts, cooperation, coercion, and persuasion are always present in International Relations. So the study of International Relations involves a study of conflict and conflict resolution among nations.

Power as the Means as well as End in IR:

Power is both means as well as an end in International Relations. Every nation uses power for their national interest and each and every nation is continuously working for acquiring, increasing and maintaining their National Power. so International relations is a continuous struggle for power between and among nations.

IR involves continuous interaction among Nations:

International Relations involves continuous interaction between and among the nations. The interaction can be cooperative, competitive, or conflictual in nature. Every nation interacts with each other through various treaties, economic ties, diplomatically arranged meetings, etc. In the era of interdependence, the scope of interactions among and between the nations is becoming a  continuous process.
