He was born in Lisbon, on 14 July 1758, in the Senhorio dos Lagares d’El-Rei, which at the time belong to the parish of Anjos, and baptized on 10 August. He was the son of Antão de Almada and his cousin D. Violante Josefa de Almada Henriques, daughter of D. Lourenço de Almada. Lourenço was educated in Terceira, during his father's governorship of the Captaincy of the Azores. He was the Grand Master of Ceremonies to the Royal House, deputy of the Estates-General, and president of the Royal Treasury's Board of Administration and Collections. He was master of the Majorat of Lagares d´El-Rei, 11th master of Pombalinho and was in the Order of Christ, Alcalde and Commander of Proença-a-Velha, Commander of São Miguel de Acha and of São Vicente de Vimioso.
Captaincy-General
He obtained the post of Lieutenant-Colonel of the Cavalary and, just like his father, became the Captain-General of the Azores, becoming the third in the position. Nominated on 15 July 1795, he disembarked to much pomp in Angra on 6 November 1799, the day that he took power, even as the Regent increased his powers in the colony. Afonso de Ornelas, in his research on the family, who: "around the Azores, in function of the role of deputy of the Estates-General, when the first French peninsular invasion,...he was a patriotic wind, that the Almadas was an authentic symbol when the independence of the country was in danger...going as far as revolting against local interest who wanted to thank Napoleon for his reception of Portuguese deputies who had gone to compliment Bayonne, who had requested that one of the princes return to Portugal to act as regent." One of Lourenço's first initiatives was to pardon Azorean deserters who did not wish to fight in the Napoleonic Wars on the peninsula. His reasonable style would come back to haunt him later, as recruitment in the Azores would be difficult: farmers would be wary of sending troops, and the Captain-General would attempt recruitment in moderation. During his tenure he accomplished many measures in the public good, that included the creation of mathematics classes in the Castle of São João Baptista, that would become the embryo for the Military Academy. He was also instrumental in promoting the cultivation of Irish potatoes and flax/hemp on the islands. There are also indications that he was a cavaleiro during Portuguese-style bullfighting between 11 August and 25 October 1787, during a festival in Angra. When he arrived in the Azores, he was accompanied by his wife, who died on 22–23 November 1801, following the birth of his eldest son. She was buried in the Chapel of Nossa Senhora das Dores, in the interior of the Church of São Francisco in Angra. Her death had a destabilizing effect on the Count, whose moderating style was abandoned and he began abusing his powers, resulting in his substitution in 1804. In October 1804, or 1805, with the arrival of his successor, he departed for Lisbon, possibly on the illustrious brigantine, called Conde de Almada, that years earlier had brought a vaccine to protect against the smallpox.
