We read all the lead to present a different history.
At the end of the 15th century, with Columbus discovering the American continent as an opportunity, Europe began the era of great colonization, relying on advanced firearms to carry out "crushing" conquest of civilizations that were still in the era of cold weapons, so that the colonial flags of European countries flew all over the world!
Relying on the continuous blood transfusion of colonies, European countries have gradually become the "bellwethers" of modern civilization, and Spain and Britain have successively known as "empires where the sun never sets", when colonies were a necessary condition for Europe to be strong.
But when World War II ended in 1945, the necessary condition that had made Europe strong began to gradually collapse! As a colony, a "wave of independence" arose, and the attitude of most European countries was "to go".
According to the theory that the larger the land under control, the more resources and populations are available, and the more the country can recover," it is unimaginable that Europe will abandon its rich colonies.
However, judging from the facts of historical development, areas with huge land have been established independently one after another! As for why European countries gave up their colonies?
First of all, when we say that the European countries themselves "created evil", it may be a lesson learned from the American Revolutionary War in 1775, afraid that if the colonies develop a full industrial system, they will "kill" their "suzerains" in Europe, so for a long time The European colonists strictly forbade the colonies to have an independent industrial system.
The immediate result of this is that the colonies can only grow and produce a single crop or mineral, which means that you can produce "food", but the iron tools used in cultivation are preferably not completely self-sufficient.
Therefore, the economy of the colony is very fragile, and if it loses the cooperation of the "suzerainty", it will collapse immediately. And because during World War II, Hitler almost threw the whole of Europe to the sky, and post-war Europe was reduced to ruins.
The European countries that had been able to digest the raw materials of the colonies fell into an indigestible dilemma, and the chain reaction that followed was that the colonial economy fell to the brink of collapse, which in turn brought about social unrest, and the direct result of social unrest was a sharp rise in the military expenditure of the European countries in the colonies.
And the high military expenditure was completely unbearable for the European countries that were in urgent need of money to rebuild their homeland, so for the European people at that time, the colonies were no longer a continuous supply of blood, but a burden to their own name.
So when the European colonies declared their independence, most countries chose to acquiesce, such as Burma, Malaysia, South Africa, Australia, etc., and they won independence only through consultation with the "suzerainty" of Europe.
Moreover, we say that the external factors that prompted Europe to abandon it were not all European countries willing to "negotiate" the abandonment of their colonies, Indonesia, Vietnam, and Algeria, all of which were brutally suppressed by the "suzerainty" of Europe in their struggle for independence.
But just when the colonial countries were about to collapse, the United States and the Soviet Union appeared, and as new superpowers, they did not want the so-called "empire of the sun never set" to appear again in the European countries, so they began to demand that Europe restrain its behavior on the grounds of "national self-determination".
It may be that some people have more courage to support themselves, and the result of "national self-determination" is often independence, so that under the impetus of the United States and the Soviet Union, Europe has lost the "legitimacy" of controlling the colonies again, and at the same time, in the shock of death, there is no "courage" to forcibly suppress.
