PETER III OF PORTUGAL

Queen Maria I and King Pedro III

'Pedro III, King-consort of Portugal' (pron. IPA []) or 'Peter III' (July 5 1717 – May 25 1786) became King-consort of the Kingdom of Portugal and Algarves by the accession of his wife and niece Queen Maria I in 1777, and co-reigned alongside her until his death.
Pedro was the younger son of John V of Portugal and Mary Anne of Austria. Pedro was a younger brother of Joseph I of Portugal. Their maternal grandparents were Leopold I, Holy Roman Emperor and Eleonore-Magdalena of Pfalz-Neuburg.
Pedro married Maria, Princess of Brazil, in 1760, at which time she was the heir to the throne then held by his brother José I. According to custom, Pedro thus became prince of Brazil in right of his wife. They had six children, of whom the eldest surviving son succeeded Maria as João VI on her death in 1816.
Pedro made no attempt to participate in government affairs, spending his time hunting or in religious exercises.
