In 1738, Sebastião José de Carvalho e Melo, 1st Marquis of Pombal, began a diplomatic career as the Portuguese Ambassador in London and later in Vienna. The Queen consort of Portugal, Archduchess Maria Anne Josefa of Austria, was fond of Melo; and after his first wife died, she arranged the widowed de Melo's second marriage to the daughter of the Austrian Field Marshal Leopold Josef, Count von Daun. King John V of Portugal, however, was not pleased and recalled Melo to Portugal in 1749. John V died the following year and his son, Joseph I of Portugal, was crowned. In contrast to his father, Joseph I was fond of de Melo, and with the Queen Mother's approval, he appointed Melo as Minister of Foreign Affairs.
