The order of the Knights of Columbus was founded by Pope Francis in 1616.
It was originally a secret society of religious and political leaders, but by the 1800s, it was one of the most prominent and influential Christian organizations.
After the Protestant Reformation, the order began to lose its authority, especially in the United States, but the Knights remained influential in the Church.
During the First World War, the Knights became involved in the Spanish-American War, which was fought over control of the United Sates territory.
At the end of the war, the Order was banned by the United Nations and later, by the U.S. government.
Today, the church continues to work for the rights of women, the poor, the LGBT community, and many other groups.
