The king left Lisbon that morning because his daughter asked.

The story

On 1 November 1755, All Saints' Day, King José I heard Mass at sunrise and left Lisbon, because a daughter wanted to spend the holiday outside the city. At 9:40 the earthquake hit; the churches were full. A tsunami and days of fire followed; tens of thousands died. The king lived, but afterwards feared living within walls, and the court moved into tents on the hills of Ajuda.

Context

Numbers are uncertain. Economic historian Álvaro Pereira estimates 30,000–40,000 deaths in Lisbon and 40,000–50,000 across Portugal, Spain and Morocco; other estimates range from 10,000 to 100,000. Wave heights are disputed too: a study of primary documents says long-repeated figures, such as 14–16 m at Tangier, should be abandoned. Pombal, the king's chief minister, reportedly said: bury the dead and heal the living. Records show he ordered the bodies removed the very next day, to prevent plague. The king wrote to his brother-in-law in Spain that he had no house, no servants, no subjects, no money, no bread. Today the roofless nave of the Carmo convent, founded by Nuno Álvares Pereira of Aljubarrota fame, serves as the memorial.
