The III Congress on Political Prisoners in Belarus (#WithoutJustCause) brought together former political prisoners, human rights activists, journalists, politicians, and representatives of the international community to discuss support, release, and rehabilitation of people who have suffered political persecution. On May 21, Political Prisoners' Day in Belarus, the discussion focused on solidarity as a means of survival – in prisons, penal colonies, families, and the media community.
