: Giuliano Cesarini, seniore) (1398 in Rome – 10 November 1444 in Varna, Ottoman Empire) was one of the group of brilliant cardinals appointed by Pope Martin V upon the conclusion of the Western Schism.

On 13 December 1442 Cesarini made the two parties reach an agreement in the city of Győr, where the rights of the baby Ladislas were recognized in the presence of the new King, without endangering the power of the other.

It was an unfortunate step and resulted in the disastrous defeat of the papal army at Varna (in eastern Bulgaria) on 10 November 1444, when Cardinal Giuliano Cesarini was slain in the fight.

In a letter to the Duke of Milan, his friend Aeneas Sylvius Piccolomini tells of reports that, having escaped the fray, though wounded and bleeding, Cesarini was set upon by a band of Hungarians who, in the confusion of defeat, robbed and killed him.

"Wounded in the battle, and fainting in his flight through loss of blood, he was slain near a marsh by the impious hands of the Hungarians, not at the instigation of the nobility, but through the rage of the populace; and thus breathed forth that glorious spirit which once with its sweet discourse swayed at will the assembled fathers at Basle"[4] Rumors that he had escaped proved false.
