The American Civil War is a civil war of 1861-1865 between the Union of 20 states and 4 border slave states of the North, remaining in the Union, on the one hand, and the Confederation of 11 slave states of the South.
The fighting began with the shelling of Fort Sumter on April 12, 1861, and ended with the surrender of the remnants of the army of the Confederates under the command of General Stand Waitey on June 23, 1865. During the war, about 2 thousand small and large battles took place. More US citizens died in this war than in any other war in which the US participated, including World War II.
The Vietnam War is one of the largest military conflicts of the second half of the 20th century, which left a noticeable mark on the culture and occupies a significant place in the recent history of Vietnam, as well as the United States and the USSR, which played an important role in it. Developed from 1955 until the fall of Saigon in 1975.
The war began as a civil war in South Vietnam. Later, North Vietnam was drawn into the war, later receiving the support of the PRC and the USSR, as well as the United States and its allies, who fulfilled their obligations to protect their friendly South Vietnam. As events unfolded, the war became intertwined with the parallel civil wars in Laos and Cambodia. All fighting in Southeast Asia from the late 1950s to 1975 is known as the Second Indochina War.
The war can be divided into several periods: the guerrilla war in South Vietnam, the full-scale US military intervention, and the final stage of the war.
The First World War is one of the largest wars in human history.
The formal reason for the war was the events in Sarajevo, where on June 28, 1914, the Bosnian Serb Gavrilo Princip killed the heir to the Austro-Hungarian throne, Archduke Ferdinand, and his morganatic wife Sofia Chotek. The countries participating in the First World War were divided into two opposing camps: Central Powers: German, Austro-Hungarian, Ottoman Empires and the Bulgarian Kingdom; Entente: Russian Empire, British Empire, French Republic.
In total, during the war years, more than 70 million people were mobilized in the armies of the warring countries, including 60 million in Europe, of which 9 to 10 million died. The number of civilian casualties, according to various estimates, is in the range from 7 to 12 million people, of which about 1 million died as a result of hostilities; about 55 million people were injured. The First World War served as the prologue and detonator of major revolutions, including the February and October 1917 in Russia and the November 1918 in Germany.
The Second World War is a war between two world military-political coalitions, which has become the largest armed conflict in the history of mankind.
It was attended by 62 states out of 74 that existed at that time. The fighting was carried out on the territory of Europe, Asia and Africa and in the waters of all oceans. This is the only conflict in which nuclear weapons have been used. More than 70 million people died as a result of the war, most of them civilians.
