The Singing Revolution

The Singing Revolution is a 2006 documentary film created by Americans James Tusty and Maureen Castle Tusty about the nonviolent Singing Revolution in Estonia in which hundreds of thousands of Estonians gathered publicly between 1986 and 1991, in an effort to end decades of Soviet occupation. The revolutionary songs they created anchored Estonia’s non-violent struggle for freedom.
