Мурад II
In Mehmed II's first reign, he defeated the crusade led by John Hunyadi after the Hungarian incursions into his country broke the conditions of the truce Peace of Szeged in September 1444. Cardinal Julian Cesarini, the representative of the Pope, had convinced the king of Hungary that breaking the truce with Muslims was not a betrayal. At this time Mehmed II asked his father Murad II to reclaim the throne, but Murad II refused. According to the 17th-century chronicles, Mehmed II wrote, "If you are the sultan, come and lead your armies. If I am the sultan I hereby order you to come and lead my armies." Then, Murad II led the Ottoman army and won the Battle of Varna on 10 November 1444. Halil Inalcik states that Mehmed II did not ask for his father. Instead, it was Çandarlı Halil Pasha's effort to bring Murad II back to the throne.
