Which event has the greatest influence on Brazil independence, American revelation, or the death of the king of Portugal or the death of emperor Pedro or Napoleon’s invasion of Portugal which one correct?

The correct event that had the greatest influence on Brazil's independence was the death of the king of Portugal, Dom João VI, in 1826. This event led to a period of political instability in Portugal, which eventually allowed for Brazil to declare its independence in 1822. The death of Dom João VI weakened Portuguese control over Brazil and played a crucial role in the country's path towards independence.
