Step-by-step explanation:
The history of the Berlin Blockade dates back to 1948 when the Soviet Union ordered a blockade of all land and water routes to Berlin, hoping to force the Western nations to abandon their control of the city. In response, the United States and the United Kingdom initiated the Berlin Airlift, a massive operation that supplied the besieged city by plane for almost a year.
