The paper analyzes contemporary anarcha-feministic activities in the Czech Republic. They appeared as a reaction to gender inequality in the Czech anarchist movement. In 2000 the Anarchist group of the 8th March (later called Anarcho-feminist group) came into existence. Their worldview considers the patriarchy and capitalism to be equivalent causes of the exploitation of both women and men. So they opposed so-called institutional feminism, including non-governmental groups and academic feminism and liberal feminism in general. The group follows the model of affinity group in its organizing and has introduced new creative activities to Czech anarchistic contentious repertoire.
