The roots of the Diocese of Eau Claire began in 1822 when the Oneida Indians, removing from New York state, settled near Green Bay. The first annual council of the Diocese of Wisconsin met in Milwaukee in 1847. In 1874, the General Convention of the Episcopal Church erected the Diocese of Fond du Lac from the Fond du Lac Deanery of the Diocese of Wisconsin. The remaining counties continued as the Diocese of Wisconsin until 1888, when it was renamed the Diocese of Milwaukee. Growth, time, and distance led to the erection of a third Wisconsin diocese. The Diocese of Eau Claire was created from counties of both the Diocese of Milwaukee and Diocese of Fond du Lac in 1928.
