History of the United Nations

1. Introduction

The United Nations (UN) is the world’s largest and most important international organization. It was established after the Second World War (1939–1945) to prevent future wars, promote peace, encourage friendly relations among countries, protect human rights, and support economic and social development.

Today, the United Nations serves as a platform where countries discuss global issues and work together to solve international problems.

2. Background of the United Nations

Failure of the League of Nations

Before the UN, there was another international organization called the League of Nations, established in 1920 after World War I.

Why did it fail?
