Hey There!
The Berlin Wall was built by East German troops and engineers on August 13, 1961. The wall was built to keep west Germans out, but it was built to keep eastern Germans in. Many eastern Germans were fleeing to the west because they felt that Western Germany better represented their ideals, political ideas, and culture. Hopefully this helped!
Cheers,
Izzy
