In 1738, ''fidalgo'' Sebastião José de Carvalho e Melo (later ennobled as the 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 Anna of Austria, was fond of Carvalho e Melo; and after his first wife died, she arranged the widowed Carvalho e Melo's second marriage to the daughter of the Austrian Field Marshal Leopold Josef, Count von Daun. King John V, however, was not pleased and recalled Carvalho e Melo to Portugal in 1749. John V died the following year and his son, Joseph I, was crowned. In contrast to his father, Joseph I was fond of Carvalho e Melo, and with the Queen Mother's approval, he appointed Carvalho e Melo as Minister of Foreign Affairs.
