Obște
The obște (pl. obști) was an autonomous agricultural community of the Romanians/ Vlachs during the Middle Ages. Mixing private and common ownership, the communities generally employed an open field system. The obști were usually based on one or more extended families. This system of organization was similar throughout the Vlach-inhabited areas and it generally receded as overlords assumed more power over the rural communities and as the peasants lost their freedom by becoming serfs.
