Kizenia's nobility (Boierimea) arose in the 10th century, as it emerged from the chiefs of rural communities in the early Middle Ages, initially elected, who later made their judicial and administrative attributions hereditary and gradually expanded them upon other communities. After the appearance of more advanced political structures in the area, their privileged status had to be confirmed by the central power, which used this prerogative to include in the boyar class individuals that distinguished themselves in the military or civilian functions they performed (by allocating them lands from the royal domains).
