Ceuta's historical transition from Portuguese to Spanish rule

The historical transition of Ceuta from Portuguese to Spanish control is examined through the lens of the 17th-century Iberian Union. Originally captured by Portugal in 1415, Ceuta remained under Portuguese sovereignty for 165 years.

The shift in allegiance occurred following the death of the Spanish monarch, which led to Philip II uniting the crowns of Spain and Portugal. Although Ceuta remained technically Portuguese on paper, the city's connection to the Portuguese metropole weakened due to neglect.

In 1640, when the Duke of Braganza proclaimed himself King John IV of Portugal, most Portuguese territories shifted their loyalty to the new Braganza dynasty. Ceuta, however, remained loyal to the Spanish crown. This was driven by several factors: the city relied more heavily on supplies from Algeciras and Cádiz than from Portugal, a process of Castilianization among the local nobility and clergy, and the fact that Portuguese envoys sent to communicate the change in leadership were intercepted, leaving the city without official orders to switch sides.
