Paul Weyrich, co-founder of the Heritage Foundation and patriarch of American religious conservatism, died today at the age of 66.

Weyrich coined the phrase "Moral Majority," helping Rev. Jerry Falwell organize the movement of the same name, which sought to mobilize social conservatives in the late 1970s and came to define conservative Christian political activism.

Weyrich closed out his life and political career as chairman of the Free Congress Foundation, a conservative think tank aimed at winning the "Culture War" against "the cultural and moral decay of political correctness" and liberal social values.
