Zaganos Pasha (Turkish: Zağanos Paşa; fl. 1446–1466) was an Ottoman military commander, with the titles and ranks of kapudan pasha and the highest military rank, Grand Vizier, during the reign of Sultan Mehmed II "the Conqueror". Originally a Christian who was conscripted and converted through the Devşirme system, he became a committed Muslim and rose through the ranks of the janissaries. He became one of the prominent military commanders of Mehmed II and a lala – the sultan's advisor, mentor, tutor, councillor, protector, all at once. He removed his rival, Halil Pasha, when he was the Grand Vizier amid the fall of Constantinople. He later served as the governor of Thessaly of Macedonia.
Origin and early life 
Zaganos was conscripted through the Devşirme system and rose through the ranks of the janissaries. He was originally Christian. Sources do not mention his descent. N. Iorga, citing Pusculus, says that he was of Albanian origin. E. Goldberg, R. Kasaba and J. S. Migdal say that he was either Greek or Serb. D. Nicolle, J. F. Haldon and S. R. Turnbull believes that he was of South Slavic or Albanian origin. M. Philippides believes that he was of either Greek or Albanian origin. He became a committed Muslim after conversion.
When Mehmed II was exiled in 1446, Zaganos accompanied him.
Second Vizier 
Young Mehmed II had after his return and accession (18 February 1451) confirmed Halil Pasha as his first Vizier (even though he seems to have disliked him), and raised Zaganos Pasha from third to second Vizier. Halil Pasha had been appointed first Vizier in 1439, after the demotion of Ishak Pasha. Zaganos, who was younger, was jealous of the position of Halil Pasha.
Conquest of Constantinople 
During the Siege of Constantinople, the bulk of the Ottoman army were encamped south of the Golden Horn. The regular European troops, stretched out along the entire length of the walls, were commanded by Karadja Pasha. The regular troops from Anatolia under Ishak Pasha were stationed south of the Lycus down to the Sea of Marmara. Mehmed himself erected his red-and-gold tent near the Mesoteichion, where the guns and the elite regiments, the Janissaries, were positioned. The Bashi-bazouks were spread out behind the front lines. Other troops under Zaganos were employed north of the Golden Horn. Communication was maintained by a road that had been constructed over the marshy head of the Horn. After the inconclusive frontal offensives, the Ottomans sought to break through the walls by constructing underground tunnels in an effort to mine them from mid-May to 25 May. Many of the sappers were miners of German origin sent from Novo Brdo by the Serbian Despot. They were placed under the command of Zaganos Pasha. However, the Byzantines employed an engineer named Johannes Grant (who was said to be German but was probably Scottish), who had counter-mines dug, allowing Byzantine troops to enter the mines and kill the Turkish workers. The Byzantines intercepted the first Serbian tunnel on the night of 16 May. Subsequent tunneling efforts were interrupted on 21, 23, and 25 May, destroying them with Greek fire and vigorous combat. On 23 May, the Byzantines captured and tortured two Turkish officers, who revealed the location of all the Turkish tunnels, which were then destroyed. On 21 May, Mehmed sent an ambassador to Constantinople and offered to lift the siege if they gave him the city. Constantine XI accepted to pay higher tributes to the sultan and recognized the status of all the conquered castles and lands in the hands of the Turks as Ottoman possession. Around this time, Mehmed had a final council with his senior officers. Here he encountered some resistance; one of his Viziers, the veteran Halil Pasha, who had always disapproved of Mehmed's plans to conquer the city, now admonished him to abandon the siege in the face of recent adversity. Halil was overruled by Zaganos, who insisted on an immediate attack. Having been accused of bribery, Halil Pasha was put to death later that year. Mehmed planned to overpower the walls by sheer force, expecting that the weakened Byzantine defense by the prolonged siege would now be worn out before he ran out of troops and started preparations for a final all-out offensive.
The stories of Halil Pasha's collaboration with the Byzantines were most likely spread by the faction of Zaganos. Zaganos succeeded Halil Pasha as Grand Vizier. In 1456, however, Zaganos was made scapegoat after a failed expedition against Hungarian-held Belgrade. Zaganos' daughter was expelled from the Sultan's harem, and the two were expelled to Balıkesir, where he probably had property. In 1459, Zaganos returned and became kapudan pasha of the fast-growing Ottoman navy, and the next year he was the governor of Thessaly and Macedonia.
Personality and appearance 
Zaganos was said to be a tall and intelligent man. He has been called the most cruel Ottoman captain of his time, and is known to have been an enemy of Christians. He was in absolute loyalty to Mehmed II, even when he was just a prince, knowing that his prospects depended on his master's success. Zaganos was a soldier who believed that the Ottoman Empire must always expand in order to keep the enemies off balance. He was known for his warlike beliefs and played an important role in the Siege of Constantinople.
Military achievements 
During the final siege of Constantinople, Zagan Pasha's troops were the first to reach the towers. Ulubatlı Hasan was the first soldier who reached the tower. During the siege many of the sappers were placed under the command of Zagan Pasha. Mehmet took Zaganos' advice almost exclusively.
Mehmet II honoured him for his loyalty and honesty, along with the Sultan's two other Viziers, Halil Pasha and Sarica Pasha, by naming the three great towers of Rumeli Hisari after them. The tower to the south is named after Zaganos Pasha.
He had a daughter who was in the Sultan's harem.
