From 1810 to 1850, the colonies in Latin America set off a wave of independence and nation-building, and China in East Asia became a semi-colonial country. Why?

This question involves the history of the Western colonial invasion phase.

1. From 1810 to 1850, the Latin American colonies opposed the early colonial aggression of Western European feudal countries such as Spain, Portugal, France and other countries. These countries colonized the Americas after Columbus discovered the New World when new shipping routes were opened. Later, as the power of these feudal countries declined, the people of Latin American countries fought bravely and unyieldingly, and gradually achieved national independence.

2. From 1810 to 1850, China in East Asia became a semi-colonial country and was invaded by emerging industrial countries such as Britain. They are capitalist countries. Having just completed the Industrial Revolution, it was grabbing colonies across the range. As a result, feudal China could not resist the aggression of emerging capitalist countries.
