Catholicism arrived in what is now the United States in the earliest days of the European colonization of the Americas. The first Catholics were Spanish missionaries who came with Christopher Columbus to the New World on his second voyage in 1493. In the 16th and 17th centuries, they established missions in what are now Florida, Georgia, New Mexico, Puerto Rico, Texas and later in California.French colonization in the early 18th century saw missions established in Louisiana, St. Louis, New Orleans, Biloxi, Mobile, the Alabamas, Natchez, Yazoo, , Arkansas, Illinois, and Michigan. In 1789 the Archdiocese of Baltimore was the first diocese established in the United States and John Carroll, whose brother Daniel was one of five men to sign both the Articles of Confederation (1778) and the United States Constitution (1787), was the first American bishop.John McCloskey was the first American cardinal in 1875.
