Which of the following events led to Brazil independence A getulio Vargas overthrow of the government B Napoleon invasion of Portugal C Simon Bolivar uprising D The liberation of enslaved Afro Brazilians

The event that led to Brazil's independence was **B) Napoleon's invasion of Portugal**. In 1807, the Portuguese royal family fled to Brazil to escape the invading French forces. This move established Brazil as the center of the Portuguese Empire and ultimately contributed to Brazil's drive for independence, which was declared in 1822. The other options, while significant in their own contexts, did not directly lead to Brazil's independence.
