Knights Templar (Freemasonry)
In the United States, a Knights Templar commandery is traditionally the final body that a member joins in the York Rite after the chapter of Royal Arch Masons and a council of Royal & Select Masters. Some jurisdictions, however, allow members to skip over membership in a council. A local Knights Templar commandery operates under a state-level Grand Commandery, however American commanderies also operate under The Grand Encampment of the United States. This is less common among American Masonic bodies, as many report to the state level alone.
