Sancho (Catalan: Sanç; 1274 – 4 September 1324), called the Pacific or the Peaceful, was King of Majorca, Count of Roussillon and Cerdanya, and Lord of Montpellier from 1311 to his death.

The Treaty of Anagni in 1295 secured their release by King James II of Aragon as well as the return of the Balearic islands to their father.

Yet another sister-in-law of Sancho, Eleanor, married his cousin (James II of Aragon's brother) Frederick III of Sicily.

[2] Sancho was of delicate constitution and prone to asthma,[1] prompting him to spend much of his time enjoying fresh air in the uplands.

In his early reign, Sancho struggled to continue his father's policy of stabilising the kingdom, but the major city of the realm, Palma de Mallorca, fought for autonomy.

[1] Sancho extorted money from the realm's Jewish population in order to build a powerful navy that would rival that of the maritime republics of Genoa and Venice, but his grandiose plans came to nothing.

He was infuriated in 1315 by the scandalous conversion of two German Christians to Judaism on the island, and responded by severely fining the Jews and confiscating all their property, including the synagogue.

He then proceeded to prepare the realm for his underage nephew's accession by establishing a regency council consisting of six people, three from the Kingdom of Majorca and three from the counties of Roussillon and Cerdagne.

[1] The arrival of Sancho's funeral procession on 11 September caused a tumult in Perpignan, with the townspeople attacking the nobles who accompanied his corpse and seizing the King's remains.
