The kibbutz was founded on 5 January 1937 by members of the Sadeh group from the Mikveh Israel agricultural school, as well as immigrants from Austria, Germany and Poland.
It was the third kibbutz established as part of the tower and stockade settlement movement.
Initially called "Kibbutz HaSadeh,"  it was later renamed in honour of Nahum Sokolov, a Hebrew writer and  Zionist leader.

Ruins of a 5th–6th century Byzantine church has been found in the kibbutz.
