Baltic Military District
The high point of the Soviet rule was reached during the Brezhnev stagnation. As there were not enough people to operate the newly built factories and order to expand industrial production, workers from outside of Latvian SSR (mainly Russians) were transferred into the country, noticeably decreasing the proportion of ethnic Latvians. The speed of Russification was also influenced by the fact that Riga was the HQ of the Baltic Military District with many thousands of active and retired Soviet officers moving there.
