Gennady Grushevoy was a professor of philosophy at the Belarusian State University from 1973. In 1988 Grushevoy began to participate actively in the democratic opposition movement, the Belarusian Popular Front (BFP). In 1989 he was arrested for organising various political actions and protest demonstrations after the Chernobyl catastrophe in Belarus.

In 1989, he created a non-governmental charitable fund dedicated to helping Belarussian children affected by Chernobyl catastrophe. The Fund was officially registered in 1990 as a non-profit, non-governmental Belarussian Charitable Fund «For the Children of Chernobyl». After the Chernobyl catastrophe, Belarus faced many problems which mainly affected the younger generation. Grushevoy has especially focused on environmental issues. The organisation promotes civil movement initiatives within Belarus and works on a variety of humanitarian programmes.

During the 1990s Grushevoy initiated the creation of numerous public, political, social-political organisations in Belarus. In 1996 he was elected to the Parliament, but as one of the leaders of the democratic opposition, he was not registered as a deputy and was not included by President Lukashenka in the House of Representatives.
