A spectacular event in the collapse of the Soviet Union that allowed for a freely elected government in Germany was the

The Berlin Wall being destructed.

Explanation:

When World War II finally ended, Germany got split up into two parts. West Germany was taken control by the Allies, while East Germany was controlled by the Soviet Union.

East Germany was run by a government that centered around communism, which overtime many people did not agree with. The citizens that resided in East Germany started leaving and going to West Germany. So many people started leaving that the government of East Germany started worrying about it and decided that they needed to take action.

This lead East German leaders to build the Berlin Wall, which separated West and East Germany from each other. If any East Germans were caught trying to move to the West, they would be imprisoned or even shot on the spot.

Eventually, people from across the globe caught word of this and wanted to help free East German people from communist rule. United States President, Ronald Reagan gave a speech in which he clearly stated he wanted to tear down the Berlin Wall and free the people. A couple of years or so later, the Berlin wall finally got torn down and the collapse of the Soviet Union came with it. This freed Germany and could now obtain a freely elected government.

the emancipation proclamation was the aim of the war change to include the freeing of slaves in addition to preserving the union. the 13th amendment, which abolished slavery in the u.s. was passed on december 6th 1865.

as promised, lincoln waited to unveil the proclamation until he could do so with success from the union military advance. on september 22nd 1862, after a victory at antietam, he publicly announced a preliminary emancipation proclamation, declaring all slaves free in the rebellious states as of january 1st 1863.
