In the Middle Ages, a commandery (rarely commandry) was the smallest administrative division of the Europeanlanded properties of a military order. It was also the name of the house where the knights of the commandery lived.[1] The word is also applied to the emoluments granted to a commander. They were the equivalent for those orders to a monastic grange. The knight in charge of a commandery was a commander.
Etymology
The word derives from French commanderie or commenderie, from mediaeval Latincommendaria or commenda, meaning 'a trust or charge', originally one held in commendam.[2][3]
Originally, commanderies were benefices, particularly in the Church, held in commendam. Mediaeval military orders adopted monastic organizational structures and commanderies were divisions of the Order of Knights of St. John of Jerusalem, and later the Order of Teutonic Knights and other knightly orders were organized along similar lines.[3] The property of the order was divided into priorates (or priories), subdivided into bailiwicks, which in turn were divided into commanderies or commendæ; these were placed in charge of a commendator or commander. The word is also applied to the emoluments granted to a commander of a military order of knights.[2]
