There are many groups in Davis that express solidarity with a broad range of social, political, international, national, local, university, worker, sex, gender, racial, religious, and city movements and groups.
Here are some of their wiki pages: Accion Zapatista Agnostic and Atheist Student Association Black Panther Party International Picnic Day Solidarity Movement Mixed Student Union Mumia Abu-Jamal SOS KDRT Students For Justice In Palestine Students Organizing for Change UCD May 1, 2007: Day of Action Women Take Back the Night
Solidarity is also the name of a Polish trade union that was founded by Lech Wałęsa, who later spoke at Freeborn Hall. Feliks (sp?), the janitor at Patwin School, was also a member of the group, and when Lech came to Davis they met at the hall, and the Davis Enterprise had a picture of them shaking hands.
