During the collectivization and repression period in 30-50s, the deported Belarusians from Western Belarus joined in 1939 significantly increased Kazakhstan’s community. 

 In the beginning of the Great Patriotic War thousands of Belarusians were evacuated to the western regions of the USSR and to Kazakhstan so as to take part in construction of military plants remote from the front line, in development of economy. In 1941, the prominent scientist Gulnitsky Leonid Vikentievich moved to Kazakhstan. He devoted half of the century working for Kazakhstan and the USSR. 

 The next, and perhaps, the biggest wave of Belarusian migration to Kazakhstan was caused by the development of the virgin and long-fallow lands. Thousands and thousands of young agricultural specialists came to Kazakhstan as volunteers so as to create new enterprises and build new settlements in the newly developed lands. 

 At that time Kazakhstan lacked specialists in organization of the use of land. The Belarusian Agricultural Academy helped much: in the period from 1955 to 1960 they sent graduates of the Land Use Department to work in Kazakhstan every year.
