Why are there no blacks in Russia?

Let me give you a brief explanation. The history of the United States is the Republic of the United States, which came into being after the War of Independence. Before that, it was a British colony, and the colony was a territory mainly managed by the British. Due to the arrival of the era of great navigation, the British Empire developed shipping and maximized profits by selling slaves, which enabled a large number of cheap slaves to appear in its own colonies, while the independent slaves in the United States were liberated. Gradually became a member of the American system, one race, and of course many races. This is why there are still black people because of the colonial history of the United States, and the history is that chauvinistic Russia has not been colonized. Most importantly, although the Renaissance was the birth of a huge and prosperous capitalist bud, it did not spread to Russia as far away as Eastern Europe. Russian humanism developed slowly, but it was indeed the most successful in Europe in the later period. Moreover, Russia's lack of maritime colonial development also laid the foundation for its inability to get involved with Africa. Have you ever heard that Russia has colonies in Africa? So that's why there are no niggers in Russia, but there are many Russian twenty cents who fled North Korea during the war. They look the same as those in China, but there are still differences. Moreover, I study here, which is quite annoying for a man who speaks fluent Russian and has an Asian face. Please choose me more when I write. Thank you.
