A burgward or castellany was a form of settlement used for the organisation of the northeastern marches of the Kingdom of Germany in the mid-10th century. Based on earlier organisations within the Frankish Empire and among the Slavs, the burgwards were composed of a central fortification (a burg) with a number of smaller, undefended villages, perhaps ten to twenty (the ward), dependent on it for protection and upon which it was dependent economically. The fortified site served as a place of refuge during attack and also as an administrative centre for tax collection, the Church, and the court
