Agricultural Co-operatives

With the introduction of the New Economic Policy in 1921, a major concern of the communist party was that the re-introduction of free trade in the countryside would result in rich peasants – known as kulaks exploiting the poor. As a counter measure, the communist party encouraged the formation of peasant co-operatives. Kaminsky was put in charge of their development, as Deputy Chairman of the Agricultural Union, and Chairman of the Union of Agricultural and Forestry Workers (Vserabotzemles), and head of several specialised centres.^[3] In this capacity, he was a leading champion of co-operatives.

During a Politburo session in January 1925, he warned that most peasants did not yet see the value of co-operating, and called for co-operatives to be given a commercial advantage over individual producers, and for co-operative chairmen to be elected, not appointed, and objected to the ruling which banned kulaks from joining co-operatives, because "it is much more profitable to have a kulak in agricultural co-operatives under our supervision than outside it.^[6] His policy was vehemently by Leon Trotsky, leader of the Left Opposition, who claimed, in July 1926, that it would lead to the co-operatives being run not by communists and poor peasants but by 'middle' peasants.^[7][8]

In 1928, after Stalin had decided to drive peasants onto collective farms, Kaminsky was appointed head of Kolkhozsentr, the main farm agency for the Russian republic. In this role, he was an enthusiast advocate of the rapid formation of large collective farms, equipped with tractors and other machinery, which he believed would be the route out of poverty for peasants struggling to subsist on small landholdings. In contrast to his earlier views, he argued that kulaks should be barred from joining kolkhozes, and should be repressed.^[9] During an agricultural conference in January 1930, he urged delegates not to fear going too far in the drive for collectivisation, because it was a "revolutionary cause".^[10]

Party official

Late in 1929, Kaminsky was appointed head of the Central Committee department for agitation and mass campaigns. From 1930 until his arrest, he was elected a candidate member of the Central Committee. In 1930, he was appointed the Secretary of Moscow State Committee of the Communist Party, rising to the rank of Second Secretary.

Commissar for Health

Kaminsky served as the for the Russian Federal Republic from 15 February 1934. In August, he was given the additional title of USSR Chief Sanitory Inspector. In July 1936, he was appointed the first USSR People's Commissar for Health.^[3] He is credited with extensive work in establishing production of medicine, preparation of medical personnel, fighting malaria in Soviet Union and promotion of medical science in education system.^[1]

Kaminsky tried to protect scientists working in the field of health from being harassed for political reasons. On 26 December 1936, Pravda published an article deploring the suppression of a bulletin that had been prepared ahead of the Second Congress of Neurologists and Psychiatrists. Kaminsky had ordered it to be withdrawn because of a paragraph which accused three named scientists of 'pseudoscience' linked to fascism and racism. He was rebuked for that, and for proposing that Solomon Levit, the founder of soviet genetics, should be elected to the praesidium of the congress, when he had recently been expelled from the communist party. In an unpublished speech, he maintained that Professor Levit could still contribute usefully to science from outside the party, and warned that "If you declare people to be fascists, you need to know that this threatens them with prison".^[4] (Professor Levit was arrested and shot in 1938)^[11] Kaminsky also protested against the practice of suppressing information about epidemics.^[4]
