The Knights of Columbus is the world’s largest Catholic fraternal service organization. Founded by Father Michael J. McGivney in New Haven, Connecticut, in 1882, it was named in honor of the mariner Christopher Columbus. Originally serving as a mutual benefit society to low-income immigrant Catholics, it developed into a fraternal benefit society dedicated to providing charitable services, promoting Catholic education and Catholic public policy positions, and actively defending Roman Catholicism in various nations.[1][2][3]
