The Diocese of Evansville () is a diocese of the Catholic Church in Southwestern Indiana. On October 21, 1944, the then-Diocese of Indianapolis was split into the Archdiocese of Indianapolis and the Diocese of Evansville. At the same time, all of Indiana split away from the Ecclesiastical Province of Cincinnati to form the new Ecclesiastical Province of Indianapolis, of which the Diocese of Evansville is a suffragan see. Statistics and extent The Diocese of Evansville includes all or part of 12 counties in Southwestern Indiana, (of note Harrison Township in Spencer County, the location of St. Meinrad Archabbey, is part of the Archdiocese of Indianapolis.) As of 2014, it pastorally served 90,800 Catholics (17.8% of 510,626 total) in 69 parishes (grouped into 4 deaneries) and 4 missions with 71 priests (66 diocesan, 5 religious), 59 deacons, 234 lay religious (6 brothers, 228 sisters) and 10 seminarians. History The Diocese of Evansville was founded on October 21, 1944, at which time it included 5 deaneries (Evansville, Jasper, Vincennes, Princeton, and Washington), 63 parishes and missions, 49,737 Catholics, and 75 diocesan priests. Henry Grimmelsman, a priest of the Archdiocese of Cincinnati and rector of the Pontifical College Josephinum in suburban Columbus, Ohio, was named the first bishop, and Assumption Church in downtown Evansville was named the cathedral. The diocese purchased the John Augustus Reitz Home from the Daughters of Isabella for use as the chancery and bishop's residence. The Catholic population of the diocese grew rapidly in the post-war years and 12 new parishes were founded between 1944 and 1962 among suburban areas of Evansville and Jasper and the small towns of Fort Branch and Bloomfield, while mission churches in New Harmony and Oakland City were elevated to parish status. The population growth necessitated the building of new schools as well, and three high schools in Evansville – Mater Dei on the west side, Rex Mundi on the north side, and Magister Noster, a high school seminary – were founded, along with high schools in Ferdinand, Loogootee, and Vincennes, and a college operated by the Sisters of St. Benedict in Ferdinand. Catholic social institutions also experienced growth with the founding of Memorial Hospital, sponsored by the Sisters of the Little Company of Mary, in Jasper, and the construction of a new facility on Evansville's east side for St. Mary's Medical Center, sponsored by the Daughters of Charity.
