Peaceful relations persist between Constantinople and the Ottoman Empire until May 26, 1421, when Mehmed dies.

The reign of Mehmed I as sultan of the reunited empire had lasted only eight years before his death, but he had also been the most powerful brother contending for the throne and de facto ruler of most of the empire for nearly the whole preceding period of elevenyears of the Ottoman Interregnum that passed between his father's captivity at Ankara and his own final victory over his brother Musa Çelebi at the Battle of Çamurlu.

Mehmed is buried in Bursa, in a mausoleum erected by himself near the celebrated mosque which he built there, and which, because of its decorations of green porcelain, is called the Green Mosque.

Mehmed I also completed another mosque in Bursa, which his grandfather Murad I had commenced but which had been neglected during the reign of Bayezid.

Mehmed had founded in the vicinity of his own Green Mosque and mausoleum two other characteristic institutions, one a school and one a refectory for the poor, both of which he has endowed with royal munificence.
