Housing movements in the USA

Have conflicts around issues of housing given rise to "social movements", in the USA? Looking at the expectations for broad social change that have been attached to such movements in the recent past, the answer would have to be that housing alone has never provided the core of such a movement. However, an extensive review of the history of struggles around housing in the USA over the last two centuries suggests that housing issues can, under certain circumstances, became the subject of social struggles in which residents, as residents, can play a significant role in confronting systemic societal problems. Those circumstances are ones in which class (labor, employment, production) issues are linked to ideological/political issues, with housing issues as a major point of contact.
