The Knights of Columbus (K of C) is a global Catholic fraternal service order founded by Blessed Michael J. McGivney. Membership is limited to practicing Catholic men. It is led by Patrick E. Kelly, the order’s 14th Supreme Knight.
The organization was founded on March 29, 1882, as a mutual benefit society for working-class and immigrant Catholics in the United States. In addition to providing an insurance system for its members, it has grown to support refugee relief, Catholic education, local parishes and dioceses, and global Catholic social causes. The Knights of Columbus have played an active role in politics ever since its formation and promote the Catholic view on public policy issues around the world.
As of 2024, the Knights reported having over 2.1 million members around the world. Women may participate in K of C through the Columbiettes and other female auxiliaries, and boys may join the Columbian Squires. The Order comprises four different “degrees”, each one of which exemplifies one of the core principles of the order. There are more than 17,000 local Knights of Columbus councils around the world, including over 400 on college campuses.
