Also in 1989 the Communist government in Hungary started to negotiate organizing of competitive elections which took place in 1990. In Czechoslovakia and East Germany, mass protests unseated entrenched Communist leaders. The Communist regimes in Bulgaria and Romania also crumbled, in the latter case as the result of a violent uprising. Attitudes had changed enough that US Secretary of State James Baker suggested that the American government would not be opposed to Soviet intervention in Romania, on behalf of the opposition, to prevent bloodshed. The tidal wave of change culminated with the fall of the Berlin Wall in November 1989, which symbolized the collapse of European Communist governments and graphically ended the Iron Curtain divide of Europe.
