The Kingdom of Majorca was a realm on the east coast of Spain, which included certain Mediterranean islands, and which was founded by James I of Aragon, also known as James the Conqueror. In a will written in 1262 after the death of his firstborn son Alfonso, he ceded the kingdom to his son James. The disposition was maintained during successive versions of his will and so when James I died in 1276, the Crown of Aragon passed to his eldest son Peter, known as Peter III of Aragon or Peter the Great. The Kingdom of Majorca passed to James, who reigned under the name of James II of Majorca. After 1279, Peter III of Aragon established that the King of Majorca was a vassal to the king of Aragon. The title continued to be employed by the Aragonese and Spanish monarchs until its dissolution by the 1715 Nueva Planta decrees.

Menorca or Minorca is one of the Balearic Islands located in the Mediterranean Sea belonging to Spain. Its name derives from its size, contrasting it with nearby Mallorca. Its capital is Mahón, situated on the island's eastern end, although Menorca is not a province and forms a political union with the other islands in the archipelago. Ciutadella and Mahón are the main ports and largest towns. The port of Mahón is the second biggest natural port in the world.
