As of the year 1400, China had by far the best, the biggest, and the largest number of, ocean-going ships in the world. Between 1405 and 1432 the Chinese sent 7 ocean-going fleets, the so-called treasure fleets, out from China. Those fleets comprised hundreds of ships; they had total crews of 20,000 men; each of those ships dwarfed the tiny ships of Columbus; and those gigantic fleets sailed from China to Indonesia, to India, to Arabia, to the east coast of Africa, and down the east coast of Africa. It looked as if the Chinese were on the verge of rounding the Cape of Good Hope, coming up the west side of Africa, and colonizing Europe.
Well, China's tremendous fleets came to an end through a typical episode of isolationism, such as one finds in the histories of many countries. There was a new emperor in China in 1432. In China there had been a Navy faction and an anti-Navy faction. In 1432, with the new emperor, the anti-Navy faction gained ascendancy. The new emperor decided that spending all this money on ships is a waste of money.

Now contrast that with what happened with ocean-going fleets in Europe. Columbus was an Italian, and he wanted an ocean-going fleet to sail across the Atlantic. Everybody in Italy considered this a stupid idea and wouldn't support it. So Columbus went to the next country, France, where everybody considered it a stupid idea and wouldn't support it. So Columbus went to Portugal, where the king of Portugal considered it a stupid idea and wouldn't support it. So Columbus went across the border to a duke of Spain who considered this stupid. And Columbus then went to another duke of Spain who also considered it a waste of money. On his sixth try Columbus went to the king and queen of Spain, who said this is stupid. Finally, on the seventh try, Columbus went back to the king and queen of Spain, who said, all right, you can have three ships, but they were small ships. Columbus sailed across the Atlantic and, as we all know, discovered the New World, came back, and brought the news to Europe. Cortez and Pizarro followed him and brought back huge quantities of wealth. Within a short time, as a result of Columbus having shown the way, 11 European countries jumped into the colonial game and got into fierce competition with each other. The essence of these events is that Europe was fragmented, so Columbus had many different chances.
