In the 1960s, the early years of the Brezhnev stagnation, dissidents in the Soviet Union increasingly turned their attention civil and eventually human rights concerns. The fight for civil and human rights focused on issues of freedom of expression, freedom of conscience, freedom to emigrate, punitive psychiatry, and the plight of political prisoners. It was characterized by a new openness of dissent, a concern for legality, the rejection of any 'underground' and violent struggle. It played a significant role in providing a common language and goal for many Soviet dissidents, and became a cause for diverse social groups in the dissident millieu, ranging from activists in the youth subculture to academics such as Andrei Sakhrarov.
