In 1946, after WW2 was over, Germany was left in shambles and was in the hands of the Allies and Soviets.The allies in the west and Soviets in the east.
While West Germany was thriving and getting back up on it's feet the east was not. The people in the east saw how well the west were doing and started to leave . It wasn't very difficult for them for them to leave because there were only barbed wired fences and not it was not heavily guarded.
HAHAHAH!!! Now they will never leave.
Since there were so many people leaving the east for the west, the Soviets decided to build a wall in 1961.
Even though the wall was built, people still tried to cross over with landmines, attack dogs and guards ready to take their lives.
I want FREEDOM
Whilst the wall help stop many people from leaving, others thought outside the box, by digging underneath and making tunnels.
Many people were trying to just get away from the horrible east. Others had family on the other side trying to reconnect but they never could until it 1990 and the wall that tore them apart got taken down a year later.
