Majorat is an arrangement giving the right of succession to a specific parcel of property associated with a title of nobility to a single heir, based on male primogeniture. A majorat (fideicommis) would be inherited by the oldest son, or if there was no son, the nearest male relative. This law existed in some European countries and was designed to prevent the distribution of wealthy estates between many members of the family, thus weakening their position. Majorats were one of the factors facilitating the evolution of aristocracy.
