Although the Diocese of Green Bay was not officially created until 1868, the history of the Catholic faith in the area dates back to 1634 when Jean Nicolet landed near Green Bay. He was soon followed by Jesuit missionaries dedicated to spreading the gospel to the native people along the Fox, Wolf, and Menominee Rivers.

For nearly a century, the Indians, missionaries, and French Canadian voyagers kept the faith alive.

First Missionary Arrives

Fr. Claude Allouez, a Jesuit missionary, celebrated Mass with the Native Americans near the present site of Oconto on Dec. 3, 1669, the feast of St. Francis Xavier. Fr. Allouez established St. Francis Xavier Mission there.

The mission was moved to Red Banks (along the southeast shore of the Bay of Green Bay) for a short time in 1671, and then to De Pere, where it remained until 1687, when it was burned.

The missionaries continued working with the Fox, Sauk, and Winnebago tribes under the protection of the French and newly constructed Fort Francis (now west Green Bay). Fort Francis was destroyed in 1728. Catholicism then lay dormant in the area for almost a century.

Green Bay was originally part of the Quebec Diocese, before becoming part of:

  • the Baltimore Diocese (1791)
  • Bardstown, Ky. (1808-21)
  • Cincinnati (1821-33)
  • Detroit (1833-43)
  • Milwaukee (1843-68)

Catholicism Revived in Northeastern Wisconsin

The establishment of Fort Howard in 1816 built upon the settlements of the Catholic French Canadians (who had been in the area since the mid-1700's). A log church-school, blessed as St. Francis Xavier Chapel, was erected in 1825, near the corner of the present Adams and Mason Streets. It burned shortly thereafter.

After a visit by Bishop Edward Fenwick, OP, of Cincinnati, a church was built in Shantytown on land that is now part of Allouez Cemetery. The church was named St. John the Evangelist and is the oldest continuing parish in Wisconsin (1831).

St. John, a primarily French-speaking congregation, became the mother parish for all the churches in the Diocese of Green Bay, including:

  • St. John Nepomucene (Little Chute), 1836
  • St. Edward (Mackville), 1849
  • St. Peter (Oshkosh), 1850
  • Holy Maternity of Mary, Manitowoc Rapids, 1850
  • St. Luke, (Two Rivers), 1851
  • St. Anna (St. Ann), 1851
  • St. Mary (now St. Francis Xavier Cathedral), 1851.

The growing Catholic population led Pope Pius IX to establish the Diocese of Green Bay on March 3, 1868, with 40,000 Catholics scattered over 15,378 square miles. The area shrunk in size with the establishment of the dioceses of Superior (1905) and Madison (1946).

Ethnic Parishes Serve Immigrant Population

Throughout the mid-to-late 1800's immigrants poured in, forming their own ethnic parishes in Green Bay, including:

  • St. Mary (now St. Francis Xavier Cathedral), formed by Germans in 1851
  • St. Willebrord (Dutch, 1864)
  • St. Patrick (Irish, 1865)
  • Ss. Peter and Paul (Belgians, 1875)
  • St. Mary of the Angels (Polish, 1898)

Intermarriage and the English language gradually weakened the bonds of the ethnic parishes.
