Murad II Kodja (June 1404, Amasya – 3 February 1451, Edirne) (Ottoman Turkish: Murād-ı sānī, Turkish:II.

Murat) is the Sultan of the Ottoman Empire from 1421 to 1451 (except for a period from 1444 to 1446 when his son Mehmed II reigns.

Murad II's reign is marked by the long war he fought against the Christian feudal lords of the Balkans and the Turkish emirates in Anatolia, a conflict that lasts 25 years.

He is brought up in Amasya, and ascends the throne on the death of his father Mehmed I.

His mother is Valide Sultan Emine Hatun, daughter of Suleyman Bey, ruler of Dulkadirids, his father's third consort.

Their marriage serves as an alliance between the Ottomans and this buffer state.
