1. Japan: A Nation Reborn

As you mentioned, 1947 was a pivotal year for Japan’s modern identity.

• The First Post-war General Election: In April, Japan held its first general election under the new constitution, leading to the formation of the Katayama Cabinet—the first socialist-led government in Japanese history.

• The Truman Doctrine (March): U.S. President Harry S. Truman announced that the United States would provide political, military, and economic assistance to all democratic nations under threat from authoritarian forces. This is often cited as the official start of the Cold War.

• The Marshall Plan (June): The U.S. proposed a massive economic aid package to help rebuild Western Europe, aiming to prevent the spread of communism by stabilizing European economies.⁵

• The Partition of India and Pakistan (August): British rule in India ended, leading to the creation of two independent nations: India and Pakistan.⁶ This triggered one of the largest mass migrations in human history.
