Speaking of Cossacks, people must be familiar with them. It can be said that it is famous and famous. Cossack cavalry can be seen everywhere in Russia's external expansion. They acted as deep-water bombs for Russian aggression and expansion, and were known as "the czar's whip". Napoleon once said: If I have Cossack cavalry in my army, I will use them to sweep the world. Cossacks can get such high praise, so what kind of people are Cossacks?

Strictly speaking, the Cossacks are not a nation, but a military group, a group of robbers composed of bankrupt farmers, unemployed workers and hooligans. Among them are Mongolians, Slavs, Georgians and Caucasians. Except the Jews, they all took refuge, and they were all called Cossacks.

Cossack was formed in the golden tent khanate period. /kloc-in the third century, many Slavs could not bear the oppression of Mongols and Slavic nobles and landlords, and fled to the grasslands in southern Russia, where they merged with the local natives and lived a nomadic life. They call themselves "Cossacks", which means "free men" in Cossack Turkic. Due to the harsh local environment, most of the fugitives fled to the local area. Coupled with the long-term war, these fugitives are fierce, cruel and ruthless. According to their place of residence, they gradually formed many Cossack ethnic groups, such as the Don Cossack, ural river Cossack, Zaporoze Cossack and Volga Cossack.

After the collapse of the Golden Horde, Russia rose, and Russia soon noticed the savage, brave, tenacious and loyal Cossacks. Russia lured and gathered Cossacks through money and land, and formed a powerful Cossack cavalry. Cossacks don't have any beliefs. They will do anything as long as they pay. Cossack soon became a deep-water bomb for Russia's external expansion, and Russia's expansion to Siberia was almost entirely dependent on Cossack. The brutal Cossack cavalry is an important force for Russia. Cossack cavalry played an important role in resisting Polish invasion and French invasion. They not only helped Russia expand its territory and fight against foreign enemies, but also helped the Russians counter the rebellion and repeatedly attacked unruly Chechens. Countless Chechens died under their butchers, so Chechens were afraid to hear their names. Cossack cavalry also committed numerous crimes during the Russian invasion of northeast China.

During World War I, as many as 300,000 Cossack cavalry fought side by side with the Russian army and fought very hard in the war. After the October Revolution, the Cossacks split, some joined the Red Army and some joined the White Army, and the two sides fought happily. It is said that millions of Cossack cavalry were killed in the civil war. After the end of the civil war in the Soviet Union, the Cossacks were suppressed and divided by the Soviet Union. Since then, the scenery has disappeared, and most Cossacks put down their butcher knives and lived a quiet life. The Silent Don by sholokhov, a Soviet writer, describes the life of Cossacks in the Don Valley before and after the October Revolution.

During the Second World War, Cossack cavalry once again took up sabers and went to the battlefield because of the tight war and the country was in danger, which made great contributions in the Battle of Stalingrad. Of course, some Cossacks who didn't want to endure Soviet oppression took the opportunity to rebel and established the Cossack Republic, but it was wiped out by the Soviet Red Army in a few days. After the end of World War II, the Cossacks lost their place, soon became silent, gradually disappeared, gradually became ordinary people, and were mixed into the sand by the Soviet Union.
