Final answer:
The leading nations of Europe (except Britain) favored intervening in Latin America in the early 1820s to assert control and exploit its resources.
Step-by-step explanation:
In the early 1820s, the leading nations of Europe, except Britain, favored the idea of intervening in Latin America to assert control over the territory. They were concerned about the ability of the new republics in Latin America to maintain their independence and feared that other European powers might try to expand their influence in the region. However, Britain opposed this intervention as they had extensive trade with Latin America and issued a joint statement with the United States warning against imposing their will on the former Spanish colonies.
This action of intervention was part of a new form of imperialism in Latin America known as neo-imperialism. The new governments of Latin America quickly became indebted to British banks, and the countries became economically dependent on a handful of exports controlled by foreign nations. This neo-imperialism continued well into the 21st century and had a negative effect on Latin American society, accentuating the class divide and hindering industrialization.
Thus, the leading nations of Europe, except Britain, favored intervening in Latin America in the early 1820s to assert control over the territory and exploit its resources.
