Not much
There were several major events that happened after WW1. One was a type of influenza that killed over twenty million people world wide. Another major event was the formation of the League of Nations. The only major world power that did not join was the United States. The Congress at that time regressed to an isolationist mode. There is no evidence, however, that if the US was in the League of Nations that it would have resulted in any major change in the history of the world. Germany and Japan as an example simply dropped out of the League. The League was worthless and allowed more wars.
History relates to the records of the activities of man that have been recorded (by man). Before history one moves into the realm of archeology. The geological era in which History first happened is called the Quaternary.
No major events happened in 1301. Andrew III of Hungary died, Edward II became the first Prince of Wales, and the Battle of Breukelen took place. Nothing Earth shattering.
One important event was when Brazil gained independence of Portugal in 1822. Another was that most Brazilians originated from the major groups.
Richard Taylor won the Nobel Prize in physics for verifying quark theory. For other choices of events please see the link.
a major event is something very big that has happened
One major event in the history of Brazil occurred in 1945 when the country became a member of the United Nations. Another major event occurred in 1962 when Brazil won the World Cup. A third major event happened in 2011 when the country elected its first female president.
One major event that happened in Lao's history was when the Chinese tried to invade the area in the 19th century but the French stopped them. The French then took over the country. In 1953, Laos was given independence.
