Introduction to International Relations

What is International Relations?
International Relations (IR) is the study of how countries, international organizations, and other global actors interact with each other. It covers everything that happens across national borders — war and peace, trade and economics, diplomacy, human rights, and global problems like climate change or terrorism.
Simply put, IR asks the question: How do states and other actors behave in the world, and why?

Why Study International Relations?
We live in an interconnected world. What happens in one country affects others. For example:
A war in the Middle East raises oil prices globally.
A financial crisis in America affects economies worldwide.
A pandemic in China spreads across the entire planet.

IR helps us understand these connections and find ways to manage global problems through cooperation, negotiation, and international rules.

Key Actors in International Relations

1. States (Countries)
States are the most important actors in IR. A state has four basic features:
A defined territory
A permanent population
A government
Sovereignty (the right to rule itself without interference)

Examples: Pakistan, USA, China, India, France.

2. International Organizations (IOs)
These are organizations created by multiple states to work together on common goals.
United Nations (UN) — maintains peace and security
World Trade Organization (WTO) — regulates global trade
International Monetary Fund (IMF) — manages global finance

3. Non-Governmental Organizations (NGOs)
These are private organizations that work on global issues independently of governments.
Amnesty International (human rights)
Red Cross (humanitarian aid)
Greenpeace (environment)

4. Multinational Corporations (MNCs)
Large companies that operate in many countries and have significant economic and political influence.
Example: Apple, Shell, Toyota

5. Individuals
Sometimes individual leaders, activists, or thinkers shape international events. For example, Nelson Mandela influenced global politics around apartheid and human rights.
