By the end of World War II, the Soviet Union had invaded and taken over much of Czechoslovakia. The Communist Party officially came to power in February 1948, and under its rule dissidents faced persecution by secret police, censorship was enforced, Marxist-Leninist ideology was proclaimed mandatory in schools, and all schools, media, and businesses became the possessions of the state.
The Baltic republics of Latvia, Estonia and Lithuania achieved their independence from the Soviet Union by conducting movements based on nonviolence. Tactics included: nonviolent protests, noncooperation, and defiance to combat Soviet military intervention and political intrusion. The problems for Latvia in particular were born after the Soviet occupation following World War II. From that point forward the Soviet leaders employed a program to eradicate the previous Latvian society and to force the “Sovietization” of Latvian society.
Russia first occupied Lithuania and introduced a program of “Russification,” an attempt to eliminate Lithuanian language and culture in favor of Russian culture, in the mid-19th century. After 22 years of independence from Russia, the Molotov-Ribbentrop Pact in 1939 reintroduced the Soviet Union’s dominance over Lithuania—as well as the other Baltic states: Estonia and Latvia. The Soviet Union publicly stated that Lithuania had joined the USSR willingly, although secret protocols of the pact disputed this. Following World War II, the Soviet Union reoccupied Lithuania.
