Other forms: collectivized; collectivizing
To collectivize is to give up individual ownership of an industry and form a collaborative group instead. In the early 1930s, the Soviet Union collectivized almost all of its agricultural land into large-scale shared farms.
Collectivize means "to form into a collective," a term that’s most often associated with communism. In the Soviet Union, it was Joseph Stalin who came up with the idea of collective farms as a way to boost productivity and free peasants from poverty. However, some historians see collectivization as one of the causes of the Soviet Union's terrible famines during the 1930s.
