Václav Havel was the influential leader during the Velvet Revolution in Czechoslovakia, which took place in late 1989. As a playwright and dissident, he played a pivotal role in advocating for democratic reforms and human rights under a repressive communist regime. The Velvet Revolution was characterized by non-violent protests and mass demonstrations, leading to the peaceful overthrow of the Communist Party. Havel's leadership and vision were instrumental in the transition to democracy, which eventually led to his presidency. His legacy continues to inspire movements for democracy and freedom in various parts of the world.
