Callixtus III (Latin: Callistus PP. III, Italian: Callisto III; 31 December 1378 – 6 August 1458; Catalan: Calixt III, Spanish: Calixto III), né Alfons de Borja, was Pope from 8 April 1455 to his death in 1458.
He is the most recent pope to date to take the name "Callixtus" upon being elected Pope.
Alfons de Borja was born in La Torreta, now a neighbourhood of Canals, Valencia – today in Spain – but at that time in the Kingdom of Valencia under the Crown of Aragon. He was the son of Domingo de Borja and Francina Llançol. During the western schism he supported Antipope Benedict XIII, and was the driving force behind Antipope Clement VIII's submission to Pope Martin V in 1429. His early career was spent as a professor of law at the University of Lleida and then as a diplomat in the service of the Kings of Aragon, especially during the Council of Basel (1431–1439). He became a cardinal after reconciling Pope Eugene IV with King Alfonso V of Aragon.
He was raised to the papal chair in 1455 as Callixtus III at a very advanced age, as a "compromise candidate" in the papal conclave that year. He is viewed by historians as being feeble and incompetent. In 1456, he issued the papal bull Inter Caetera to Portugal (not to be confused with Inter Caetera of 1493). This bull reaffirmed the Portuguese right to reduce infidels and the Moors to servitude by the earlier bulls Romanus Pontifex and Dum Diversas, thus reaffirming the papal consent to the enslavement of Africans. This confirmation of Romanus Pontifex also gave the Portuguese the military Order of Christ under Prince Henry the Navigator.
Inter Caetera of 1456 was in direct opposition, however, to the stance taken by Pope Eugene IV in the 1435 bull Sicut Dudum, where infidels were acknowledged to have been created in the image of God and having souls, which implied that no Christian had the right to take away their liberty.
On 20 February 1456, Pope Callixtus III elevated two of his nephews to the position of cardinal. The first of them was Rodrigo de Borja ("Borgia" in Italian), who later became Pope Alexander VI (1492–1503), infamous for his alleged corruption and immorality. The second was Luis Julian de Milà.
On 29 June 1456, Callixtus ordered the church bells to be rung at noon (see noon bell) as a call to prayer. As the order spread, the ringing of the bells was taken also as a crusading call to lift the Siege of Belgrade. The Siege of Belgrade took place on 22 July and was a notable victory against the Turks. To commemorate this victory, Callixtus III ordered the Feast of the Transfiguration to be held on 6 August.
He approved of the founding of the University of Greifswald that took place in the year 1456.
Callixtus III's pre-papal coat of arms featured a grazing ox.
The "bull against the comet" 
According to one story that first appeared in a 1475 posthumous biography and was subsequently embellished and popularized by Pierre-Simon Laplace, Callixtus III excommunicated the 1456 apparition of Halley's Comet, believing it to be an ill omen for the Christian defenders of Belgrade from the besieging armies of the Ottoman Empire. No known primary source supports the authenticity of this account. The 29 June 1456 papal bull of Callixtus III calling for a public prayer for the success of the crusade, makes no mention of the comet. By 6 August, when the Turkish siege was broken the comet had not been visible in either Europe or Turkey for several weeks.
