  The Soviet Union imposed heavy control on city growth, preventing some cities from reaching their full potential while promoting others.
  
  For the entirety of its existence, the most populous cities were Moscow and Leningrad (both in Russian SFSR), with the third far place taken by Kiev (Ukrainian SSR). At its inception, the Top 5 was completed by Kharkov (Ukrainian SSR) and Baku (Azerbaijan SSR), but, by the end of the century, Tashkent (Uzbek SSR), which had assumed the position of capital of Soviet Central Asia, had risen to fourth place. Another city worth mentioning is Minsk (Byelorussian SSR), which saw rapid growth during the 20th century, rising from the 32nd most populous in the union to the 7th.
