John III of Navarre

Act by which John III and Catherine swore to uphold the fueros of Navarre after their coronation. John's name (Don Johan) is in boldface in the middle of the ninth line. John III (, , ; 1469 – 14 June 1516) was King of Navarre from 1484 until his death in 1516 as the husband and co-ruler of Queen Catherine.

King of Navarre John was the son of Alain I, Lord of Albret, and Frances, Countess of Périgord.

John became King of Navarre and Count of Foix by virtue of his marriage to Queen Catherine in 1484. He shared with Catherine tasks related to the government of the kingdom, but his rule was marked by the guardianship of Catherine's mother Magdalena de Valois up to 1494—she died in 1495—and persistent diplomatic and military pressure of Ferdinand II of Aragon over the Crown of Navarre, supported on the ground by the Beaumont party of Navarre.

John and Catherine were crowned as monarchs in Pamplona on 10 January 1494. In the run-up to the ceremony, Louis of Beaumont—count of Lerín—had taken over and ransacked the stronghold. On Christmas 1493, the count blocked the access of the king and queen to the capital city, but after a fleeting peace agreement was reached, the ceremony was held. In the week-long festival following the crowning ceremony, John III and his father are referred to in Basque language verses as Labrit, their usual naming in Navarre—also at Olite in 1493, document written in Romanic language.

The kingdom invaded In 1512, Navarre was invaded by a combined Castilian-Aragonese army sent by Ferdinand II of Aragon, whose second wife was Germaine de Foix (1490–1538), a cousin of Queen Catherine. The Castilian troops commanded by the duke of Alba crossed the Pyrénées onto Lower Navarre capturing St-Jean-Pied-de-Port on 10 September 1512 and wreaking havoc across much of the merindad. There the Castilians were doggedly opposed by lords loyal to John III and Catherine of Navarre, but the Castilians retained St-Jean-Pied-de-Port and its hinterland.

On 18 February 1513 Pope Julius II issued a papal bull excommunicating King John III de Albret and Queen Catherine de Foix of Navarre for supporting King Louis XII of France in his conflict against the Papal States.

Following the invasion, Navarre south of the Pyrenees was annexed to Castile nominally as an autonomous kingdom (aeque principalis) by the victorious Ferdinand after taking an oath to respect the Navarrese laws and institutions (1515).

The royal family took shelter in Béarn, a royal Pyrenean domain and principality contiguous to Lower Navarre. In 1510, the Parliament of Navarre and the States-General of Béarn had passed a bill to create a confederation with a view to ensuring a better defence against external aggression. The capital city of Béarn was Pau, which John III and Catherine took as their main base along with Orthez and Tarbes in their last period.

Reconquest attempt and death After the Aragonese king Ferdinand's death in January 1516, the king John III mustered an army in Sauveterre-de-Béarn made up of Navarrese exiles and men from all over his domains, especially from Béarn, but the total figure of combatants amounted to no more than several hundreds. The advance of the two columns led by Pedro, Marshal of Navarre was stopped by the Castilians right on the Pyrénées due to spies informing Cardinal Cisneros. The reconquest attempt was flawed.

Depressed by the defeats and adverse diplomatic results, John III died at the castle of Esgouarrabaque in Monein, Béarn, on 17 June 1516 after lying gripped by fatal fevers. Up to the last moment he struggled to get Navarre back from the Spanish, urging his wife, Queen Catherine, to send a representative to the Cortes of Castile to demand the restoration of the kingdom of Navarre. Despite his wish to be buried at the Santa Maria Cathedral of Pamplona, the permanent Spanish occupation prevented that. His corpse rests instead at the Cathedral of Lescar along with Queen Catherine, who outlived him only a few months.
