== History ==
=== 1826 to 1957 ===
Central Minnesota went through several Catholic jurisdictions before the Vatican erected the Diocese of New Ulm:
Diocese of Saint Louis (1826 to 1837)
Diocese of Dubuque (1837 to 1850)
Diocese of Saint Paul (1850 to 1875)
The New Ulm area would remain part of the Diocese of Saint Paul, followed by the Archdiocese of Saint Paul, for the next 107 years. The first Catholic church in the city of New Ulm, Holy Trinity, was started in 1857, but was demolished during the Dakota War of 1862. Another was built in 1871, then destroyed by a tornado ten years later. The current Holy Trinity church was completed in 1903.
=== 1957 to 2000 ===
On November 18, 1957, Pope Pius XII founded the Diocese of New Ulm, taking its territory from the Archdiocese of Saint Paul. The pope named Alphonse Schladweiler as the first bishop of New Ulm. During his 18-year tenure, he ordained 64 priests and organized St. Isadore Parish in Clarkfield (1960) and Lady of the Lakes Parish in Spicer (1962). In 1972, Schladweiler founded a diocesan newspaper, the Newsletter, and the diocesan pastoral council. He also established a mission in Guatemala, assuming responsibility for staffing a parish in San Lucas Tolimán. Schladweiler retired in 1975.
The second bishop of New Ulm was Raymond Lucker, named by Pope Paul VI in 1975. He placed one of his parishes under interdict until every member received psychological counseling. This happened after a religious sister, trained in New Age spirituality, replaced a crucifix in the church sanctuary with a "cosmic pillow." Lucker retired in 2000.
=== 2000 to present ===
Pope John Paul II named Auxiliary Bishop John Nienstedt from the Archdiocese of Detroit as the third bishop of New Ulm in 2001. He told Catholics not to read Lucker's book on Catholic doctrine. Nienstadt became coadjutor archbishop of the Archdiocese of Saint Paul and Minneapolis in 2007.
Nienstedt's replacement in New Ulm was John M. LeVoir, named by Pope Benedict XVI in 2008. In 2017, the diocese filed for Chapter 11 Bankruptcy following numerous sexual abuse lawsuits against diocesan clergy. LeVoir retired in 2020.
As of 2023, the bishop of New Ulm is Chad Zielinski, formerly bishop of the Diocese of Fairbanks.
