Dom Pedro I was the first Emperor of Brazil, known for his role in the country's independence from Portugal in 1822. Born in 1798, he was the son of King João VI of Portugal. Pedro became a key figure in Brazil's history when he declared the nation's independence, famously shouting "Independência ou Morte!" This act marked the beginning of a new era for Brazil as a sovereign nation. After declaring independence, Dom Pedro I ruled Brazil until 1831, when he abdicated the throne in favor of his son, Dom Pedro II. His reign was marked by significant political and social changes, including the establishment of a constitutional monarchy. Despite his abdication, Pedro I's legacy remains influential in Brazilian history.
