Alfonso IV, called the Kind was King of Aragon and Count of Barcelona from 1327 to his death. His reign saw the incorporation of the County of Urgell, Duchy of Athens, and Duchy of Neopatria into the Crown of Aragon.
James I the Conqueror was King of Aragon and Lord of Montpellier from 1213 to 1276; King of Majorca from 1231 to 1276; and Valencia from 1238 to 1276 and Count of Barcelona. His long reign—the longest of any Iberian monarch—saw the expansion of the Crown of Aragon in three directions: Languedoc to the north, the Balearic Islands to the southeast, and Valencia to the south. By a treaty with Louis IX of France, he achieved the renunciation of any possible claim of French suzerainty over the County of Barcelona and the other Catalan counties, while he renounced northward expansion and taking back the once Catalan territories in Occitania and vassal counties loyal to the County of Barcelona, lands that were lost by his father Peter II of Aragon in the Battle of Muret during the Albigensian Crusade and annexed by the Kingdom of France, and then decided to turn south. His great part in the Reconquista was similar in Mediterranean Spain to that of his contemporary Ferdinand III of Castile in Andalusia. One of the main reasons for this formal renunciation of most of the once Catalan territories in Languedoc and Occitania and any expansion into them is the fact that he was raised by the Knights Templar crusaders, who had defeated his father fighting for the Pope alongside the French, so it was effectively forbidden for him to try to maintain the traditional influence of the Count of Barcelona that previously existed in Occitania and Languedoc.
Peter III of Aragon was King of Aragon, King of Valencia, and Count of Barcelona from 1276 to his death. At the invitation of some rebels, he conquered the Kingdom of Sicily and became King of Sicily in 1282, pressing the claim of his wife, Constance II of Sicily, uniting the kingdom to the crown.
Peter IV, called the Ceremonious, was from 1336 until his death the king of Aragon, Sardinia-Corsica, and Valencia, and count of Barcelona. In 1344, he deposed James III of Majorca and made himself King of Majorca.
Martin the Humane, also called the Elder and the Ecclesiastic, was King of Aragon, Valencia, Sardinia and Corsica and Count of Barcelona from 1396 and King of Sicily from 1409. He failed to secure the accession of his illegitimate grandson, Frederic, Count of Luna, and with him the rule of the House of Barcelona came to an end.

The Crown of Aragon was a composite monarchy ruled by one king, originated by the dynastic union of the Kingdom of Aragon and the County of Barcelona and ended as a consequence of the War of the Spanish Succession. At the height of its power in the 14th and 15th centuries, the Crown of Aragon was a thalassocracy controlling a large portion of present-day eastern Spain, parts of what is now southern France, and a Mediterranean empire which included the Balearic Islands, Sicily, Corsica, Sardinia, Malta, Southern Italy and parts of Greece.

The history of Valencia, one of the oldest cities in Spain, begins over 2100 years ago with its founding as a Roman colony under the name "Valentia Edetanorum" on the site of a former Iberian town, by the river Turia in the province of Edetania. The Roman consul Decimus Junius Brutus Callaicus transferred about 2,000 veteran soldiers who had fought under him to Valentia in 138 BC. Valentia lay in a strategic location near the sea on a river island that would later be crossed by the Via Augusta. Pompey razed Valentia to the ground in 75 BC; it was rebuilt about fifty years later with large infrastructure projects, and by the mid-1st century, was experiencing rapid urban growth with many colonists from Italy.
