The Solidarity movement, started in 1980 as a series of labor strikes, formed into a large trade union and then a political movement demanding workers' rights, actual worker control over means of production, and similar socialist policies. It finally forced and won a public election in 1989 (on the very same day of the Tiananmen square crackdown) which in turn led to the end of communist (and Russian) rule in Poland.
When oliver Anthony sings that he's an old world man struggling to live in a new world, all I think about is how strong the old world fought to unionize the work force. I didn't even know about it until this year. The 1900s labour movement was intense and interesing. Especially reading about it from the future which helps put a lot of current politics into perspective.
