In the 1970s and 1980s, intellectuals in the Soviet Union and other Communist states, and in some other countries, began to focus on civil resistance as the most promising means of opposing entrenched authoritarian regimes. The use of various forms of unofficial exchange of information, including by samizdat, expanded. Two major revolutions during the 1980s strongly influenced political movements that followed. The first was the 1986 People Power Revolution, in the Philippines from which the term 'people power' came to be widely used, especially in Hispanic and Asian nations. Three years later, the Revolutions of 1989 that ousted communist regimes in the Eastern Bloc reinforced the concept (with the notable exception of the notoriously bloody Romanian Revolution), beginning with the victory of Solidarity in that year's Polish legislative elections. The Revolutions of 1989 provided the template for the so-called color revolutions in mainly post-communist states, which tended to use a color or flower as a symbol, somewhat in the manner of the Velvet Revolution in Czechoslovakia.
