Peter Tatchell has been tirelessly campaigning for LGBTI human rights around the world for five decades. He staged the first gay rights protest in a communist country in East Germany in 1973, twice attempted a citizen’s arrest of the president of Zimbabwe Robert Mugabe (in 1999 and 2001) and was beaten by neo-Nazis at Moscow Pride parade in 2007.

In 1990 Tatchell was a founding member of the LGBT direct action organisation OutRage! He started campaigning for same-sex marriage in the UK in 1992. In 2011 his friends and allies founded the Peter Tatchell Foundation, of which he is director, to support UK and worldwide human rights campaigns.
