"Woke" was originally a word in the US black community to refer to people who were class conscious. Specifically to be aware of cooptation and trickery by the bourgeoisie and police. Ironically, like a lot of black slang, it was coopted by whites and its meaning was changed to suit their interests.

Due to the association with activists, it came to mean progressivism, then liberalism, and by that point had fallen out of favor by its original users. Now it just means "thing me no like" for conservatives.
