Taking the Maidan square became an established Ukrainian protest repertoire in 1990.

Evidence

When the government tried to dislodge the protesters, fifty thousand Ukrainians marched to join them. It worked. Ukraine did not exit negotiations on Gorbachev’s new union treaty, as they asked—but the protesters were allowed to present their case on television, and the right to protest was affirmed. This was the first time that “Maidan” could be used as a name for an act of contention, rather than a place, and the moment that taking this square became an established part of the Ukrainian repertoire. — Vincent Bevins, If We Burn, 472
