Answer: Velvet Revolution, Vaclav Havel
Explanation: In November 1989, in Prague, which was then the capital of Czechoslovakia, non-violent protests took place, known as the Velvet Revolution, although the police falsified the excessive use of force in response to these peaceful demonstrations. Communist Party of Czechoslovakia, in order to prevent any tragic consequences from this behaviour of the police, renounced its power, allowing the unilateral state to be transformed into a federation and become the Czech and Slovak Federative Republic, which lasted from 1989 to 1992. Vaclav Havel was elected president of this federation, which, after the final dissolution of the federation in two independent states, i.e. the Czech Republic and Slovakia, was President of the Czech Republic from 1993 to 1998.
