Many Latin American countries in the twentieth century turned to  "communism and socialism".

Socialism is generally viewed as an economic framework that looks to accomplish equity among individuals from society. Communism, is both an economic framework that looks for correspondence among individuals from society and a political philosophy that advocates a classless and stateless society and rejects religion.
