Maria I

▪ queen of Portugal

born Dec. 17, 1734, Lisbon, Port.

died March 20, 1816, Rio de Janeiro, Brazil

      the first queen regnant of Portugal (1777–1816).

      Maria was the daughter of King Joseph. In 1760 she married her uncle who, as king consort after Maria's accession (February 1777), became Peter III. Maria attempted to correct the harshness of her father's minister, the marquês de Pombal, freeing his political prisoners and banishing him to Pombal; but an inquiry ended in his pardon. She abandoned some of his trading enterprises but developed small industries in Portugal and new crops in Brazil.

      The deaths of Peter in 1786 and of Maria's elder son Joseph in 1788, combined with news of the excesses of the French Revolution, so affected Maria that she suffered a mental collapse in January 1792. She entrusted power to her second son, John (the future John VI), who assumed the title of prince regent in 1799, when her condition was deemed incurable. Maria proved incapable of resuming her duties, and when Napoleon's armies invaded Portugal in November 1807, she went with the rest of the royal family to Brazil, where she died.
