sentences:  The two years governed by the coalition of the center-left Partido Republicano Radical and the center-right CEDA were marked by mostly clandestine CNT activity, in the face of severe government repression.During the socialist October Revolution of 1934 (at which point membership in the CNT reached 1.58 million) the CNT participated only from the background.However, the CNT's Regional Confederation of Labour of Asturias, León and Palencia actively participated in the revolution because of its loyalty to workers' alliances, this time formalized through the Uníos Hermanos Proletarios (UHP; Unite Brothers of the Proletariat) in the pact with the UGT and the Asturian Socialist Federation.
