How did the construction of the berlin wall affect the country of germany?

The wall divided Berlin into two parts for 28 years, separating families and friends.

At the end of World War II, Berlin was divided into four sectors of occupation:  Soviet, American, French and English.

The bad relations between the communists and the allies grew until they reached the point where two coins emerged, two political ideals and, finally, two Germanies.

This is how Germany affected the construction of the Berlin Wall.
