In Spanish colony 1820, Brazil became independent, while in 1840, China became a semi-colony of Britain and France. Why?

Brazil is America, close to Europe, and they invaded earlier, while China was far away, and their forces could not invade until the19th century.

Spain and Portugal rose earlier and had great influence in the early days, occupying all the places they could find. When Britain and France rose, they almost all occupied it, so they could only occupy new land. . . .

And because of time, the development of the colony itself and the decline of the country. . In short, there are many reasons. The colony will not last long, and it will definitely become independent within a certain period of time. Spain occupied a large area of American territory from 1500, I forgot. By 1820, the suzerain country could not cover the colonies, and Brazil and other countries began to become independent. . .

However, it was not until the 9th century A.D./KLOC-that the West arrived and invaded China. At that time, the most powerful Britain and France took the lead in the war, and China gradually became a colony. . . . .

What you said about suppressing the old colonies was only done by the sovereign state. They could not suppress it for hundreds of years, and the power of the colonial people was growing. Spain, the suzerain country, frequently participated in wars in the European continent, consuming its national strength, and the Armada was destroyed by Britain. . . . . . After 1800, Napoleon was defeated and perished, and the whole government was exiled to a Brazilian colony, and it had no right to suppress the colony. . .

Brazil's independence is also something special. It was the son of the Spanish emperor who ruled Brazil and declared its independence, and the emperor acquiesced. . .

The United States was almost divided between Spain and Portugal before the rise of Britain and France, so Britain and France invaded other places everywhere when they rose. . . . When the Western forces arrived in China, only Britain and France had the ability. . . . And at that time, the world was almost divided, only near China. . . . . At that time, Spain and other early colonial empires declined. Spain and Portugal only saw in the 1900 sad treaty that they sent troops to form an eight-nation alliance with other countries. After the war, they also sent people to sign treaties behind PP to earn some money. . . Portugal occupies only a small area in Macao. . . .

Besides, it seems easier to conquer a new place and suppress an old colony. . . When the backward areas are defeated, they lose their resistance. Once defeated, the Qing government did not dare to go to war with the West, and kept paying reparations to cede territory. . . . Once the old colonies need to be suppressed, it shows that chaos has begun, and the more money and people spent on repression, the worse the effect. . . . .

For example, your achievements and pleasure when you have a new love, and her meekness.

Compared with spending money and time to appease an old lover's growing ambition and impatience and disgust when he is greedy,

Which one do you want to be?
