USA HISTORY

Detailed explanation-1: -The Berlin Wall (German: Berliner Mauer, pronounced [bɛʁˌliːnɐ ˈmaʊ̯ɐ] ( listen)) was a guarded concrete barrier that encircled West Berlin from 1961 to 1989, separating it from East Berlin and East Germany (GDR). Construction of the Berlin Wall was commenced by the government of the GDR on 13 August 1961.

Detailed explanation-2: -The Berlin Wall: Building the Wall In just two weeks, the East German army, police force and volunteer construction workers had completed a makeshift barbed wire and concrete block wall–the Berlin Wall–that divided one side of the city from the other.

Detailed explanation-3: -From this barbed wire barricade, the Wall would eventually develop into a fortified concrete structure encircling West Berlin and isolating it from the surrounding East German territory. In this photograph, construction workers are supervised by East German guards as they build part of the Berlin Wall in 1961.

Detailed explanation-4: -By the 1980s, this system of walls and electrified fences extended 28 miles through Berlin and 75 miles around West Berlin, separating it from the rest of East Germany. The East Germans also erected an extensive barrier along most of the 850-mile border between East and West Germany.
