Iberian Union
1582 CE – 1639 CE · 814,268 km²

The Iberian Union, or the Hispanic Monarchy, describes the period from 1580 to 1640 in which the Monarchy of Spain under the Habsburg dynasty, then the personal union of the crowns of Castile and Aragon, brought in personal union also the Kingdom of Portugal. It incorporated the entire Iberian Peninsula, except Andorra and French territory, as well as Portuguese and Spanish overseas possessions, under the Spanish Habsburg monarchs Philip II, Philip III, and Philip IV.

Origins and Founding
The Battle of Alcácer Quibir in 1578 saw the death of the young king Sebastian. Sebastian's granduncle and successor, Cardinal Henry, was 66 years old at the time. Henry's death was followed by a succession crisis, with three grandchildren of Manuel I claiming the throne: Infanta Catarina, Duchess of Braganza (married to John, 6th Duke of Braganza), António, Prior of Crato, and King Philip II of Spain. António had been acclaimed king of Portugal by the people of Santarém on 24 July 1580, and then in many cities and towns throughout the country. Some members of the Council of Governors of Portugal who had supported Philip escaped to Spain and declared him to be the legal successor of Henry. Philip marched into Portugal and defeated the troops loyal to the Prior of Crato in the Battle of Alcântara.

Wars and Battles
Decline and Fall
The subsequent Portuguese Restoration War against Philip III (Portuguese: Guerra da Restauração) consisted mainly of small skirmishes near the border. The most significant battles were the Battle of the Lines of Elvas (1659), the Battle of Ameixial (1663), the Battle of Castelo Rodrigo (1664), and the Battle of Montes Claros (1665); the Portuguese were victorious in all of these battles. However, the Spaniards won the Battle of Vilanova (1658) and the Battle of the Berlengas (1666). The Battle of Montijo (1644) was indecisive, starting out with great Spanish success and ending with Portuguese success; the numbers of casualties were nearly equal.

Several decisions made by John IV to strengthen his forces made these victories possible. On 11 December 1640, the Council of War was created to organize all the operations.

The Spanish city of Ceuta was a part of the Portuguese Empire until the end of the Iberian Union in 1640, after which it decided to remain with Spain. Thus the coat of arms of the city is nearly identical to that of the Kingdom of Portugal, showing the seven castles over the red bordure and the five escutcheons with silver roundels, and the gyronny field of its flag is identical to that of the flag of Lisbon, to commemorate the fact of that flag having been the first raised in Ceuta by the Portuguese when they conquered the city in 1415.
