Labour Cooperative Agricultural Farm
Labour Cooperative Agricultural Farm (Bulgarian: Трудово кооперативно земеделско стопанство) known in its Bulgarian acronym TKZS is an agricultural cooperative in the People's Republic of Bulgaria on the Soviet model. The TKZS were initially and by design voluntarily created, but the mass collectivization of land often led to violent measures to socialize the property of a large part of the rural owners - especially the richest.
