Brazil is the largest country in South America with a population of over 186 million people. It has a mostly tropical climate and borders every South American country except Chile and Ecuador. While Portuguese is the main language, the culture has influences from indigenous groups and Portuguese colonists. Some notable aspects of Brazilian culture include feijoada as the national dish and soccer as the most popular sport. Brazil gained independence from Portugal in 1822 and transitioned to democracy in the late 20th century, though it still faces issues with unequal wealth distribution.
