answer:
fidel castro, who came to power in cuba in 1959, brought about significant changes to the country. he nationalized many private businesses, including farms and industries, and implemented policies to redistribute wealth and resources. he also implemented universal healthcare and education, which significantly improved access to these essential services for the cuban population.
castro's government also established close ties with the soviet union, which provided economic and military support to cuba. this led to tensions with the united states, which implemented a trade embargo on cuba that remains in place to this day.
also suppressed political dissent and human rights, with many cubans fleeing the country as a result. despite these criticisms, castro remained popular among many cubans who saw him as a revolutionary leader who stood up to U.S. imperialism and improved the lives of ordinary cubans.
