Key Moments

The USA was the most powerful region at this time. Europe made some contributions.

The period from 1945 to 1989 was known as the Cold War. The USA and its allies were lined up against Russia (then known as the Soviet Union) and its allies. Many proxy wars occurred between the two powers fought on other countries' territory. The war between Vietnam and the USA (1954 to 1975) was the longest conflict of the 20th century. Other long standing flashpoints involved areas claimed by different peoples or countries (for example, Kashmir and Palestine).

The 8808m highest mountain in the world (Tibetan: Chomolunga; Nepalese: Sagarmata; English: Everest) was fist climbed by New Zealander, Edmund Hillary and Nepalese, Tenzing Norgay in May 1953, part of a British team lead by John Hunt.

On 4 October 1957, Russia launched the first object (Sputnik I) to leave the Earth's atmosphere and orbit the Earth. On 19 July 1969, the first humans walked on the Moon (Neil Armstrong and Buzz Aldrin from the USA).

In 1992 Pope John Paul II declared that the Catholic Church was wrong to condemn Galileo Galilei in 1633 for teaching that the Earth revolved around the Sun.

In late 2004, an earthquake in the Indian Ocean generated a tsunami that killed over 250,000 people. In 2005 a fierce hurricane devastated parts of the USA, killing thousands. The historic city of New Orleans is virtually destroyed in an event widely attributated to global warming.
