(Name taken: Innocent X)
The papal conclave of 1644 was the papal conclave of Cardinals called on the death of Pope Urban VIII. It lasted from 9 August to 15 September 1644 and eventually chose Giovanni Battista Pamphili, who took office as Pope Innocent X.
Urban's influence 
The reign of Pope Urban VIII (which included the costly First War of Castro) had been financially troubling for Rome and for the Church and the ongoing conflict for control of the Church between Spain and France and the ongoing Thirty Years' War meant many cardinals arrived at the conclave seeking a compromise which would bring stability to the Church.
But Urban's reign had also subjected the Church to his notorious nepotism. He had appointed three family members as Cardinals; his brother Antonio Marcello Barberini and his two nephews, Francesco Barberini and Antonio Barberini. His nephews, especially, were keen to retain the wealth, power and property they had amassed during their uncle's reign and both sought to move the conclave in their favour.
They started by hiring, it was rumoured, bands of brigands and mercenaries to roam the streets of the city causing trouble, creating noise and generally making it uncomfortable for the cardinals inside the conclave.
Split conclave 
Somewhat disingenuously, Francesco sided with the cardinals loyal to Spain. Urban VIII had been a strong francophile and the mood of the conclave was with Spain from the beginning. Antonio, at the direction of Cardinal Jules Mazarin, sided with the cardinals loyal to France and was supported with funding from the French with which he was to buy wavering votes.
So rather than working for consensus, the two brothers split the conclave. When voting started on 29 August, Antonio Barberini put Giulio Cesare Sacchetti forward as a candidate but without great success. The following day, Francesco Barberini nominated Giovanni Battista Pamphili with much the same result.
At a stand off, the brothers then sought to win each other over. Antonio Barberini moved about the conclave offering all form of incentives to the various cardinals, from official positions to cash to Spanish supporters in return for switching their vote in favour of Sacchetti. The deals were to be brokered by the recently arrived French Ambassador and would likely have been concluded had the ambassador not tried to slip advantageous clauses into the agreement when it came time for the brothers to agree. The new agreement signed 20,000 doubloons over to the ambassador and his family in return for acting as agent between the two parties. Antonio furiously withdrew the offer and broke off negotiations.
Pamphili elected 
Though it's likely he didn't have to, Francesco Barberini countered with a generous offer from the Spanish delegation which included a promise of protection for the Barberini (including Francesco himself) from King Philip IV of Spain. Antonio and his delegation agreed and the following morning, on 15 September 1644, Pamphili was elected and took the papal throne as Pope Innocent X.
French reaction 
Cardinal Mazarin had a back-up plan to exercise France's jus exclusivae against Pamphili's nomination and left for Rome but arrived too late to issue the veto. As it was, Spain's Cardinal Gil de Albornoz presented a veto against Sacchetti, putting the result beyond doubt.
Mazarin was furious and blamed the ambassador who in turn claimed Antonio Barberini had included the clause is his own agreement as an excuse for turning on the French and siding with the Spanish. Mazarin, keen to remain on good terms with the Barberini, recalled the ambassador and continued to support the Barberini. Mazarin later provided shelter for the Barberini nephews (including the cardinals' brother, Taddeo Barberini) after Innocent X had them investigated and exiled to Paris.
Furious at the power Innocent's election gave to his already-powerful sister-in-law, Olimpia Maidalchini, Cardinal Alessandro Bichi was said to have exclaimed, "We have just elected a female pope". Supporters of Bichi and the French delegation hung banners in churches calling her "Pope Olimpia I".
