It begun because USA supported capitalism and Soviet union supported communism . both were superpowers and wanted the world to side with them i.e. support them
<h2>At the end of World War II, the Soviet Union and the United States competed for global influence and power.</h2>
Historical context:
The term Cold War refers to the heightened tension that existed for almost 50 years between the United States and the Union of Soviet Socialist Republics (USSR).
Some of the deeper issues that set the USA and the USSR at odds were that the USA was committed to capitalism and democratic institutions of government, whereas the USSR was committed to communism and imposed authoritarian government. The Cold War was mostly a tension between these worldviews.There were also immediate conflicts and pressure points as the Cold War began. One of those issues was that the USA had atomic weapons and the USSR did not. (The US would not share that technology with the Soviets, who had been their ally in World War II.) When the Soviets developed their own atomic weaponry, this led to a massive arms race between the superpowers.
The break of communion between what are now the Eastern Orthodox and Roman Catholic Churches has lasted since the 11th century. The Great Schism came about due to a complex mix of religious disagreements and political conflicts. Rome believed that the pope (the religious leader of the western church) should have authority over the patriarch (the religious authority of the eastern church).
