Why did the conflict in southern Africa of some European colonialists (Boers) with others (the British) attracted the attention of the whole world? Why was no one interested in the fate of the African peoples, for whose lands the Angloburg war was fought?

But, of course, the British had incomparably more strength than the Boers. More and more reinforcements were deployed to southern Africa. By the spring of 1900, the number of British troops there had reached 200 thousand, people and continued to grow. In addition, the British managed to bribe to win over to their side some of the local tribes that had previously supported the Boers. After two and a half years of courageous resistance, in May 1902 the Boers were forced to sign a peace treaty. Both of their republics ceased to exist and became English colonies. On the eve of the XX century. the British created the world’s first concentration camps on the Boer lands, driving the wives and children of the fighting Boers there. The Angloburg War attracted the attention of the whole world. Millions of people sympathized with the struggle of the brave Boers; volunteers, including those from Russia, went to their republics to help the defenders.
