The independence of Brazil from Portugal was officially declared on September 7, 1822. This event marked the end of over three centuries of colonial rule. The movement for independence was influenced by various factors, including the rise of nationalism and the impact of the Napoleonic Wars, which weakened Portuguese control. Dom Pedro I, the son of the King of Portugal, played a crucial role in Brazil's independence. He declared, "Independência ou Morte!" (Independence or Death!) as he rejected orders to return to Portugal. Following this declaration, Brazil became an independent empire, establishing a new era in its history.
