Billy Sunday, Revivalism, Spokane
The Pacific Northwest has frequently been categorized as the least churched and least religious section of the country. And in general, most historians have accepted the notion that religion played a comparatively minor role in the development of urban life in the region. Nevertheless, during the winter of 1908-1909, as many as 35,000 people a day gathered in downtown Spokane to hear Billy Sunday preach the gospel.
