The 1755 Lisbon earthquake, also known as the Great Lisbon earthquake, impacted on Portugal on the morning of Saturday, 1 November, Feast of All Saints, at around 09:40 local time. In combination with subsequent fires and a tsunami, the earthquake almost totally destroyed Lisbon and adjoining areas. Seismologists today estimate the Lisbon earthquake had a magnitude of 8.4 on the moment magnitude scale, with its epicenter in the Atlantic Ocean about 200 km (120 mi) west-southwest of Cape St. Vincent. Chronologically it was the third known large scale earthquake to hit the city. Estimates place the death toll in Lisbon alone at between 30,000 and 50,000 people, making it one of the deadliest earthquakes in history.

The Sieges of Ceuta were a series of blockades by Moroccan forces of the Spanish-held city of Ceuta on the North African coast. The first siege began on 23 October 1694 and finished in 1720 when reinforcements arrived. During the 26 years of the siege, the city underwent changes leading to the loss of its Portuguese character. While most of the military operations took place around the city walls, there were also small-scale penetrations by Spanish forces at various points on the Moroccan coast, and the seizure of shipping in the Strait of Gibraltar. The city was placed under a second siege in 1721 until 22 April 1727.
