They really never did anything! They entered the world stage in the 1400's!! There were THOUSANDS of years of history before that. And Ancient world history revolves around the Middle East, Mediterranean and Africa. The MAYANS and Aztec indians were WAY further advanced than the Western Europeans! Even the tribes in South Africa are recorded to have been trading with Arabs and other people in the region. West Africans used to trade with the CHINESE!
The Moor wars brought Civilization and culture to Europe with the Renaissance and w/out the Asians and Africans who did that they would still be cutting people's heads off and blindly following the Anglican church! They try to take credit for Romans and Greeks in the MEDITERRANEANS!
Then the Moors were exiled out of Spain abt 5 years before Columbus sailed to America (where the Chinese had already come by 1418) and then westerners took their ignorance of the world they had NEVER known and killed anyone who didn't look like them! THEY COMMITTED GENOCIDE ON A WHOLE GROUP OF PEOPLE WHO HAD NEVER DONE ANYTHING TO THEM but help them survive! and used mercantilism and greed to enslave Africans and grow rich on the back of other people, which is what brought them to power for so long!
Its all because their original ancestors were so stupid!
