In the spring of 1420, a group of South Bohemian Hussites led by Petr Hromádka managed to seize the town of Sezimovo Ústí and the nearby Hradiště Castle. In this place they began to build the model Hussite town Hradiste Mount Tabor - shortened to Tábor - named after Mount Tabor in Galilee. Social and economic equality was promoted in the city and the Taborites addressed each other as brothers and sisters. Hussites flocked to Tábor from all over the country. Economically supported by Tábor's control of local gold mines, the citizens joined local peasants to develop a communal society. Taborites announced the Millennium of Christ and declared there would be no more servants and masters, all property would be held in common and there would be no more taxation. They promised that people would return to a state of pristine innocence. Some historians have found parallels to modern nationalist revolutionary movements. Murray Bookchin argues that this was an early example of anarcho-communism.
