Cold War Chronology: Berlin Blockade

The Berlin Blockade was a significant early event in the Cold War. It began on June 24, 1948, and ended on May 12, 1949. During this period, the Soviet Union blocked all rail, road, and canal access to the sectors of Berlin controlled by the Western Allies.

Cold War Chronology: Berlin Wall Construction

The Berlin Wall's construction started on August 13, 1961. This barrier was erected by the German Democratic Republic (East Germany) to prevent its citizens from fleeing to the West, becoming a stark symbol of the Cold War's division.

Cold War Chronology: Soviet Invasion of Czechoslovakia

On August 20, 1968, the Soviet Union and its Warsaw Pact allies invaded Czechoslovakia. This action put an end to the liberalisation program known as the Prague Spring, reinforcing Soviet control over its satellite states.

Cold War Chronology: Communist China UN Entry

The People's Republic of China was admitted to the United Nations on October 25, 1971. This resolution effectively replaced the Republic of China (Taiwan) in the UN Security Council and other bodies, marking a significant shift in international relations.

Arranging Cold War Events Chronologically

To arrange these events chronologically, we look at their respective dates:

• D. Berlin Blockade: June 24, 1948 – May 12, 1949
• A. Berlin Wall is constructed: August 13, 1961
• C. Soviet invasion of Czechoslovakia: August 20, 1968
• B. Communist China joins the UN: October 25, 1971

Based on these dates, the correct chronological order of the events is:

1. D. Berlin Blockade
2. A. Berlin Wall is constructed
3. C. Soviet invasion of Czechoslovakia
4. B. Communist China joins the UN

Therefore, the sequence D, A, C, B represents the correct chronological arrangement of these key Cold War events.
