The legacy of James I included the creation of a strategic Mediterranean enclave, including territories between two large kingdoms, the Capetians of France and the Crown of Aragon, which were in constant conflict at the time.
Conscious of the fragility of the Kingdom of Majorca, James I undertook the conquest of Cerdanya to unify the new kingdom.
He also entered into negotiations to arrange the marriage of his son James to Beatrice of Savoy, daughter to Count Amadeus of Savoy.
Neither plan was successful.

On the death of James I, the new king of Majorca, James II, decided not to pay tribute to Peter III of Aragon.
Preoccupied with diverse problems within the realm, it was not until 1279 when the Majorcan monarch reconciled to have his states recognized as subordinate to the king of Aragon.
As a consequence the Kingdom of Majorca could not hold court, and the king of Majorca was forced to go to Catalonia to present tribute to the king of Aragon.
By means of the Treaty of Perpignan in 1279, an imbalance of power between the Kingdom of Aragon and the Kingdom of Majorca was created.
The Aragonese king maintained the political and economic control of Aragon over the Kingdom of Majorca, reestablishing the unified jurisdiction of the Crown of Aragon, which was broken by the will of James I. This treaty would condition relations between the Kingdom of Majorca and the Crown of Aragon throughout the former's existence.
The lack of courts later aggravated the destabilization of a kingdom already on the brink of fracture, which, besides this, lacked any common institution beyond the monarchy.

During the Aragonese Crusade, James II of Majorca allied himself with the Pope and the French against Peter of Aragon.
As a result, Peter's successor Alfonso conquered the kingdom in 1286.
However, by the Treaty of Anagni in 1295, James II of Aragon was required to restore the Balearics to James of Majorca.

On the death of James II of Majorca's son Sancho in 1324, James III took the throne at the age of nine, necessitating a regency council headed by his uncle Philip to govern the realm.
The situation was difficult since James II of Aragon did not renounce his claim to the Majorcan throne.
In 1325, Philip secured the renunciation by the Aragonian king of any claim on the rights of succession of the Majorcan throne after the repayment of a great debt incurred by Sancho during an invasion by Sardinia.
While the act solved the problem of succession, it also plunged the kingdom into a serious financial crisis.

James was forced to develop policies similar to that of Aragon's.
To that end, he was forced to participate in the war against Genoa (1329-1336), which resulted in the loss of various economic markets for the kingdom.
Again, it was necessary to impose new taxes and fines, which were levied on the Jewish community, though this was insufficient to resolve the financial crisis.
The problems of the kingdom did not appear to have an end since in 1341, Peter IV of Aragon closed relations with the Kingdom of Majorca as a prelude to invasion.
In May 1343, Peter IV invaded the Balearic Islands and followed that in 1344 with the invasions of the counties of Roussillon and Cerdanya.
James III was able to keep only his French possessions.
After the sale of these possessions to the king of France in 1349, James III left for Majorca.
He was defeated and killed at the Battle of Llucmajor on 25 October 1349.
Then, the Kingdom of Majorca was definitively incorporated into the Crown of Aragon.
