Siabr

in Novgorod and Pskov from the 14th to 16th centuries, a co-owner of a plot of arable land or land used for trade. The term siabr changed in meaning with the process of feudalization. Peasants, secular and religious feudal lords, or merchants could be siabry. Siabry owned shares (zhereb’i) in these lands and managed them freely by concluding various transactions. There were also siabry in Lithuania, Byelorussia, and the Ukraine.
