Why can Russia continue to control the land occupied during the colonial expansion?

Russia is the abbreviation of Russian Federation and the largest country in the world. Russia's land area has reached 1709820 square kilometers, almost twice the land area of our two countries. Compared with 56 ethnic groups in China, Russia is composed of 1, 94 ethnic groups. The reason why there are so many ethnic groups is that Russia has so much land occupied by colonial expansion during the Russian period. So, why can Russia control so much land occupied during the colonial period? I think there are several reasons.

1.？ Military feudalism thought

Russia expanded so many colonies, on the one hand, because it wanted to obtain colonial resources and economic income, and more importantly, because the rulers of the Russian period had strong military feudal ideas and coveted the land of neighboring countries. For this reason, Russia's colonial expansion is not only plundering resources, but more importantly expanding the country's territory. This idea of military feudalism has been passed down to this day, so Russia's attitude towards the preservation of colonies is very tough. Even if some autonomous countries want to resist Russia, Russia will take measures to calm the reaction and continue to control the colonial land.

2.？ Mass migration

Russia has established a perfect law and constitution to rule the colonies, and also immigrated on a large scale, allowing Russian natives to immigrate to those colonial areas. The purpose of this is to make the number of local Russians occupy the majority, which is convenient for Russia to control the local area.

3. Colonial massacre and assimilation

When he first took control of the colony, the czar would order a mass slaughter of the colonists. There are not many people in those remote Siberian areas. After being massacred and assimilated on a large scale, they were even more unable to compete with powerful Russia, so they had to obediently obey Russian rule and become colonies.
