Final answer:
Marxist ideology rose among Latin American nationalists as a response to economic imperialism, inequality, and the appeal of populism, which sought to democratize power and resources in favor of the disenfranchised majority.
Step-by-step explanation:
The rise of Marxist ideology among Latin American nationalists can be attributed to several factors, all of which are grounded in the region's historical, economic, and social contexts.
Populism, a political approach aiming to appeal to ordinary people who feel that their concerns are disregarded by established elite groups, took hold in Latin America due to the widespread disenfranchisement of the majority population, often composed of people of mixed race.
This population found their interests repeatedly overlooked by the ruling white creole minority. Populism's appeal can be connected to its emphasis on addressing the needs of the general population over those of the privileged few.
In Latin America, populist leaders often arose in opposition to what was perceived as economic imperialism on the part of foreign powers, especially the United States, which appeared to support American corporate interests over democratic values.
The nationalization of industries, such as the oil industry in Mexico under President Lázaro Cárdenas, was a response to this situation, attempting to reclaim control over the nation's resources and promote economic sovereignty, although not necessarily adhering strictly to Marxist doctrines.
