Communism fell in Czechoslovakia when a demonstration in Nov led to police attacks on students, prompting an outcry against the police and gov.
A few days after this demonstration a united opposition group led by Havel (Civil Forum) was formed. Demonstrations got larger.
The communist regime didn’t arrest demonstrators but instead wanted to institute reforms to remain in power.
Meanwhile, the Civic Forum put together the ‘Programmatic Principles of the Civil Forum’ stating its goals: state of law, free elections, social justice, clean environment, educated people, return to Europe and prosperity.
