How did solidarity begin?

Solidarity originated as a social and political movement in Poland during the early 1980s, primarily driven by the labor union "Solidarity" (Solidarność) led by Lech Wałęsa. It emerged in response to economic hardships and oppressive communist rule, advocating for workers' rights and democratic reforms. The movement garnered widespread support, uniting various factions of society against the government and ultimately playing a crucial role in the fall of communism in Eastern Europe. Solidarity's ideals of cooperation and mutual support have since inspired various movements worldwide.
