Mehmed I
The Green Mosque was commissioned in 1412 by Sultan Mehmed I Çelebi, who ruled from 1413 to 1421, after a fight against his brothers to reunite the Ottoman Empire. Mehmed I was buried in a mausoleum, called the Green Tomb, commissioned by his son and successor, Murad II, which resides in the complex. The Green Mosque's exact completion date is uncertain, but it was built between 1419 and 1424. Decorative work continued on the mosque after Mehmed I's death.
