Pedro I

Pedro I., Emperor of Brazil (1798-1834), was the son of John VI. of Portugal, whom he accompanied to South America when he fled thither during Napoleon's invasion (1807). On his father's return (1821), he remained behind as regent, and in the following year was declared emperor, Brazil becoming an independent state. The constant anarchy which prevailed culminated in a revolution (1831), and Dom Pedro abdicated in favour of his son, and sailed to Europe, where he passed the remainder of his life.
