He was the son of Manuel II Palaiologos and Helena Dragaš, and the brother of John VIII Palaiologos and Demetrios Palaiologos. Constantine XI Palaiologos was crowned emperor after the death of his brother John VIII Palaiologos, who had participated in the Council of Florence alongside Pope Eugene IV and Joseph II of Constantinople.

He was the nephew of Andronikos Palaiologos and the cousin of Thomas Palaiologos and Demetrios Palaiologos. Before his accession to the throne, Constantine XI Palaiologos served as the Despot of the Morea, governing the Morea region alongside his brothers Thomas Palaiologos and Demetrios Palaiologos.

The empire's relationships with other nations, such as the Republic of Venice and the Kingdom of Hungary, were crucial in determining its fate. Constantine XI Palaiologos sought to strengthen the empire's defenses by forming alliances with John Hunyadi and Pope Nicholas V, but these efforts ultimately proved unsuccessful. The Fall of Thessalonica in 1430 and the Siege of Belgrade in 1456 demonstrated the empire's vulnerability to Ottoman attacks, which were led by Mehmed II and Halil Pasha.

The Theodosian Walls were eventually breached, and the city was conquered on May 29, 1453. Notable figures such as Giovanni Longo Giustiniani and Orhan Çelebi played important roles in the siege, which was also influenced by the Treaty of Edirne and the Ottoman-Hungarian Wars. The fall of Constantinople had significant consequences for the Eastern Orthodox Church and the Patriarch of Constantinople, as well as for the Roman Catholic Church and the Pope.
