The Enforcement Acts of 1870-1871 were criminal codes that protected African-Americans' and white Republicans' right to vote. The main goal of these acts was to fight against the KKK and the White League, which were targeting black people, and, later, other groups.

Answer:
On the night of November 9, 1989, the Berlin Wall—the most potent symbol of the cold-war division of Europe—came down. Earlier that day, the Communist authorities of the German Democratic Republic had announced the removal of travel restrictions to democratic West Berlin. Thousands of East Germans streamed into the West, and in the course of the night, celebrants on both sides of the wall began to tear it down.
The collapse of the Berlin Wall was the culminating point of the revolutionary changes sweeping East Central Europe in 1989. Throughout the Soviet bloc, reformers assumed power and ended over 40 years of dictatorial Communist rule. The reform movement that ended communism in East Central Europe began in Poland. Solidarity, an anti-Communist trade union and social movement, had forced Poland’s Communist government to recognize it in 1980 through a wave of strikes that gained international attention. In 1981, Poland’s Communist authorities, under pressure from Moscow, declared martial law, arrested Solidarity’s leaders, and banned the democratic trade union. The ban did not bring an end to Solidarity. The movement simply went underground, and the rebellious Poles organized their own civil society, separate from the Communist government and its edicts.
