User: What's the capital city of Czechoslovakia?
Assistant: Czechoslovakia is no longer a sovereign state. It ceased to exist following the deposition of its communist leaders in a process known as the Velvet Revolution. Following the fall of that regime it split peacefully at the end of 1992 into the Czech Republic and Slovakia. The capital cities of those two nations are Prague and Bratislava respectively. While Czechoslovakia was in existence Prague was its capital.
