What is the real root cause of the weakening of colonial rule in Spain and Portugal?

It's really complicated to say, Spain's discovery of the New World, Portugal's monopoly of Indian spices, all of which brought great wealth to the two teeth, first in the treasury of the Aztec Empire and the Inca Empire, followed by a large number of silver mines in the Chilean region, and there was a trade with West Africa, which was rich in **, and the two teeth traded with it. Then there is Portugal's black gold and spice triangle with India, West Africa, and Brazil**. These are the advantages of the two teeth, which will be analyzed in detail next.

But what are these ** goods that they really rely on? It is a cotton textile (English and French) of Northwest Europe. Specifically, cotton spinning (Britain and France) - slaves and gold mines [gold mines were taken directly] (West Africa) - cash crops (South America) triangular blacks**, these are Spanish.

In Portugal, it is a cycle of cotton spinning – gold mining – spices (India).

Both countries have taken a route, that is, they are too dependent on one kind of ** material - cotton spinning.

In fact, this is just an economic restriction, and more of it is made by Spain, what is Spain doing? He went to engage in hegemony, in a certain emperor (which II?) I can't remember exactly) period was already the control of Britain and France**.

You know, what is the most expensive to spend? It was the war, including the Spanish participation in the Battle of Lepanto at that time, which crushed the Ottoman navy.

Under the war, no matter how rich the country is, it will be dragged down, no matter how many gold and silver mines, what about the Aztec treasury, it is not spent yet...

Spain was powerless after the destruction of the Armadada, and South American navies were often harassed by British and French pirates (somewhat of a pirates). So the world after that was Anglo-French.

To sum up, what caused the decline of the two teeth:1Too much dependence on one ** goods, fattening Britain and France.

2.War costs too much money.

3.The colonial system was not perfect, and the number of immigrants was not large.

4.This is very important, but it does not need to be said, what did Spain do when they regained the lost territory, you must know that you must know the history, they drove out all the Muslims and Jews, and those who did not leave were killed, what is this concept? They drove out the best bankers in the world (Jews) and the best businessmen (Muslims) of the time, and the Muslims controlled the east, which was a mountain of gold!

Because of these wrong decisions, the strength of the two teeth has declined.

The reasons for the decline of Spain are many and complex.

Fundamentally, it is the productivity that has not kept up with the times. There is no continuing to guide the tide of the world.

Militarily, the European continent was at that time at a time of frequent wars. The biggest was the Thirty Years' War, and Spain and Portugal declined one after another.

Economically, instead of using the plundered wealth for industry and commerce, he squandered and enjoyed it, which led to the decline of his own economy, but injected sufficient capital into the development of Britain and France.

In international relations, Spain was busy competing for the throne and hegemony in Europe, and its power in the colonies declined.

In the colonies, the people were dissatisfied with colonial rule and carried out independence movements.

Constantly improve military strength, constantly improve equipment to expand outward, through their own military strength to conquer many raiding countries, let them become their own colonies.

The empire was established during the Age of Discovery, and Spain was the first to become powerful and then cooperated with other nations.

Portugal and Spain were feudal and centralized countries at that time, and the wealth plundered by colonization was not used to develop capitalist industry and commerce.
