Between 1945 and 1961, an estimated 3 million East Germans had fled to the West, thwarting committed communists' desire to build a strong economy and create a country whose citizens would not want to leave. In June 1961, East German leader Walter Ulbricht announced: "Nobody has the intention of building a wall." However, within two months a barbed-wire fence had split Berlin. Panic spread, and another 1,500 people escaped within a day of the fence going up; many who tried to scale the barrier were forced back by troops wielding bayonets and machine guns. The East German authorities imposed a law that allowed anyone to be assigned to work on the land to replace those who had fled. The barrier was increasingly strengthened in the following weeks. This early version (above left, seen from the West) was still small enough for divided families to wave at each other across the concrete. By Christmas 1961, the wall was so tall, so fortified and so heavily patrolled that such communication was almost impossible.

The sport is believed to have originated in the lakes of mid-19th century England. Originally an aquatic alternative to rugby, it was played with a "pulu", an inflated rubber ball from India. By 1900, the game, now more like soccer, was so popular that it was the first team sport to be included on the Olympic programme.
