Answer:
Step-by-step explanation:
It began in 1946 after WW2 as a means of containment between
Russia and the Western allies. At the end of the war the allies
controlled parts of Berlin and so did the Russians. It was agreed
that Berlin would be divided into 4 parts. Three of the four were
western powers and the 4th was Russian. This divided Germany into 2
parts east Germany (Russian) and western Germany (western nations). Eventually, the Berlin Wall was built and the two sides
faced off at the border until 1989 when it fell. The Cold War was
not a shooting war, but a war of threats and words.
