As a consequence of the "Vilafrancada" he left Lisbon, having returned to participate in the drafting of the "Carta Constitucional" (Constitutional Charter) which had been promised by John VI of Portugal. The king, however, never signed the Charter into effect. With the beginning of the Miguel of Portugal's reign he once again retired from public life. He would once again return to politics when in July 1833, Lisbon was taken by the liberal troops, commanded by the First Duke of Terceira.
