== History ==
=== 1700 to 1800 ===
During the 17th century, present day Illinois was part of the French colony of New France. The Diocese of Quebec, which had jurisdiction over the colony, sent numerous French missionaries to the region. It was estimated that 15,000 to 20,000 Native American converts and French trappers and settlers throughout the region were tended to by these Jesuit missionaries.
After the British took control of New France in 1763, the Archdiocese of Quebec retained jurisdiction in the Illinois area. However, most of the French Catholics in the area migrated to Louisiana.
In 1776, the new United States claimed sovereignty over the area of Illinois. After the American Revolution ended in 1783, Pope Pius VI erected in 1784 the Prefecture Apostolic of the United States, encompassing the entire territory of the new nation. In 1785, the vicar apostolic, John Carroll, sent his first missionary to Illinois. In 1787, the Illinois area became part of the Northwest Territory of the United States. Pius VI created the Diocese of Baltimore, the first diocese in the United States, to replace the prefecture apostolic in 1789.
=== 1800 to 1907 ===
When the Vatican erected the Diocese of Bardstown in Kentucky in 1808, it gained jurisdiction over the Illinois area. The jurisdiction over northern Illinois shifted in 1834 to the Diocese of St. Louis. The first Catholic mass in Elgin was conducted by two French missionaries in 1837.
With the creation of the Diocese of Chicago in 1843, northern Illinois was transferred from the Diocese of St. Louis. The Rockford area would be part of the Diocese of Chicago, followed by the Archdiocese of Chicago, for the next 64 years.
In Elgin, the first Catholic church, St. Mary's, opened in 1851. That same year, Bishop James Van de Velde of Chicago purchased land for the first Catholic church in Aurora. The first Catholic church in Rockford was St. James, founded in 1853. The first parochial school in the city was started in 1855. The footprint of the diocese continued to expand during this time with the dedication of a parish church in DeKalb in 1861.
In 1899, the Sisters of the Third Order of St. Francis opened St. Anthony Hospital in Rockford. Today it is OSF Saint Anthony Medical Center. Saint Joseph Hospital in Elgin was founded in 1901.
=== 1907 to 1942 ===
Pope Pius X erected the Diocese of Rockford on September 27, 1907. Its territory of 12 counties was taken from the Archdiocese of Chicago. The pope appointed Auxiliary Bishop Peter Muldoon of Chicago as the first bishop of Rockford. With the 1917 entry of the United States into World War I, Muldoon ministered to soldiers and recruits at Camp Grant, the US Army facility in Rockford. He died in 1927.
Auxiliary Bishop Edward Hoban of Chicago was named by Pope Pius XI in 1928 as bishop of Rockford. During his tenure, Hoban opened many elementary and high schools in the diocese, modernized charitable institutions, and established a diocesan newspaper. In 1942, Pope Pius XII appointed Hoban as coadjutor bishop for the Diocese of Cleveland.
=== 1942 to present ===
The next bishop of Rockford was Monsignor John Boylan from the Diocese of Des Moines, appointed by Pius XII in 1942. During his tenure as bishop, Boylan was able to reduce the diocese's debt while adding new parishes and schools to meet population growth. In 1948, Pope Pius XII established the Diocese of Joliet and transferred Kendall County from Rockford to Joliet. After Boylan died in 1953, Pius named Raymond Hillinger of Chicago to replace him that same year Three years later, Hillinger was made auxiliary bishop in Chicago.
Auxiliary Bishop Loras Lane from the Archdiocese of Dubuque replaced Hillinger in 1956. Lane died in 1968; Pope Paul VI named Arthur O'Neill to take Lane's place.
In 1992, William Joffe, a diocesan priest, pleaded guilty to two counts of bank fraud and one count of interstate transportation of a fraudulent check and received one year in prison. He also embezzled $265,000 from his parish in McHenry County. He spent the money on a horse farm in Harvard, Illinois, and a resort and restaurant in Wisconsin. After his release from prison in 1992, Joffe was assigned to a new parish. However, after only a few months, Joffe was suspended from the priesthood in 1993.
Serving as bishop of Rockford for 26 years, O'Neill retired in 1994. Thomas G. Doran of Rockford was the next bishop, named by Pope John Paul II in 1994. In 2011, the diocese ended its participation in state-funded adoptions and foster-care placements because the State of Illinois would no longer allow discrimination against same-sex married couples. Doran retired as bishop of Rockford in 2012. That same year, David Malloy of the Archdiocese of Milwaukee, named by John Paul II, became the next bishop.
In June 2026, the diocese sued the State of Illinois, stating that the Illinois Human Rights Act prevented Catholic institutions from discriminating against hiring candidates who support abortion rights for women.

=== Sexual abuse ===
In 2002, after the story appeared in the media, Bishop Doran confirmed that Harlan Clapsaddle, a diocese priest, had sexually abused three brothers when they were minors in the 1970s. When the victims complained about him in 1996 to the diocese, it removed Clapsaddle from ministry after an investigation. Each victim received a $27,000 cash settlement in 1997. After sending Clapsaddle away for treatment, the diocese re-assigned him to a nursing home on his return. Clapsaddle was permanently removed from ministry in 2002.
The priest Mark Campobello pleaded guilty in 2004 to two counts of aggravated criminal sexual abuse. Two women had accused him of indecent touching when they 14-and 15-years-old in 1999 and 2000. He was sentenced to eight years in prison. The Vatican laicized Campobello in 2005. The two victims sued the diocese in 2004; they reached a $2.2 million settlement with the diocese in 2007.
In November 2018, Bishop Malloy released a list of 15 clerics, including one deacon and one brother, from the diocese who had been accused of acts of sexual abuse from 1925 to 1991.In 2023, the Illinois Attorney General released a report on Catholic clergy child sex abuse in Illinois. The multi-year investigation found that more than 450 Catholic clergy in Illinois abused nearly 2,000 minors since 1950.

On September 30, 2000, John Earl, a Rockford Catholic priest, drove his car into the Northern Illinois Health Clinic after learning that the FDA had approved the drug RU-486, prescribed for medical abortions. He pulled out an ax before being forced to the ground by the owner of the building, who fired two warning shots from a shotgun. Earl was sentenced to 30 months of probation and paid over $7,000 in fines and restitution, but was not removed from the priesthood.
