The Cold War was a major part of the second half of the 20th century, as tensions arose between two of the world's biggest superpowers over differences in both ideology and philosophy.
Given the name because there was no large-scale fighting directly between the two, the USA and USSR, they instead supported major regional conflicts in various proxy wars.
The struggle for geopolitical dominance between the USA and USSR would instead often flare up indirectly, famously doing so as propaganda campaigns, espionage, rivalry at sports events and in technological competitions such as the Space Race.
The Cold War came to an end until 1991 with the collapse of the USSR, forever changing the world order and ushering in the next era of world politics.

Origins of the Cold War
Following the end of the Second World War and the surrender of the Nazis in 1945, the uneasy alliance of the United States, the UK and USSR began to unravel.
By 1948 the Soviets had installed governments in all the Eastern European states liberated by the Red Army.
Fearing permanent Soviet dominance in the region, the Americans and British began to take action to prevent the spread of communism to western European countries.
The Cold War had fully formed by 1947 when US aid provided under the Marshall Plan to western Europe had brought those helped in line with American influence and the Soviets had fully installed openly communist regimes in eastern Europe.
The two sides of the conflict had drawn lines in the sand and the power struggle had properly begun.
