What has changed after Revolution? And there was a following. Began a turn of reprisals when the whole estates of men (officers, aristocrats, scientific, doctors and businessmen) were executed, or immigrated from the country. Many were banished for life to Siberia. To authority there came people from the lowest layers of a society workers and peasants. The religion was declared "by opium for people". Many churches were destroyed, and with them and moral values. The beginning to prosper drunkenness and anarchy. Within Civil war which proceeded 2 years as the set of Russian men was lost. After war hungry 30 years when people died for famine by the whole families have begun. In 30th years many families have remained without supporters. Russian women grew children.
Then in 1941 World War which has carried away more than 20 million lifes has burst. The majority of victims there were, certainly, men soldiers and officers. There was no family in Russia in which not father was lost, the son or the brother. The whole generation of children grew without fathers. They were brought up only by mothers. Therefore many boys have grown "mother's sons" as mothers of them indulged and preserved. In the country the beginning to lack men. I think, what exactly after war of 1941-1945 years and has taken place demographic misbalance in Russia. Not only numerically women began to prevail in the country, but also at a genetic level they became stronger and hardy both morally, and physically. War has tempered them! People then at all did not suspect, as the echo of that war will sound in Russia long.
Now, in 21 century, Russian women still recollect that war, that took lives of many and many men. I shall not stop that after War some years proceeded Stalin reprisals, took away one thousand human lives. I shall as stop on consequences of wars in Vietnam and Afghanistan. Only I want to add, that all this time, from the beginning of 20 centuries and until now, die and still perish in the Chechen Republic Russian men.
