Feudalism in Europe

In the Middle Ages, a commandery (rarely commandry) was the smallest administrative division of the European landed properties of a military order. It was also the name of the house where the knights of the commandery lived. 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.
