What are now termed the former Soviet republics became independent from Moscow in 1991. For some of these countries, this was a good reason to establish equestrian statues of national heroes from the days before Soviet rule, thereby emphasizing their own identity.
Among the equestrian statues that I identified in Kazakhstan are portrayals of those who fought against the Dzungars, the last remnants of the Mongol Empire. This often happened with help from the Russian Empire, resulting in an increasing control of the Kazakh Khanate by the Russians.
