Yakub Çelebi (Turkish:Yakup Çelebi,c. 1362 – 28 June 1389) was anOttomanprince and the son ofMurad I.

He was educated from a young age and was accustomed to administrative and military education. He made a name for himself with his courage, heroism and benevolence and had been with his fatherMurad I in all his wars.^[1]

Both he and his half-brotherBayezid I fought well in theBattle of Kosovo, the last expedition of their father Murad I. During the battle, Yakub Çelebi led the left flank of the army and was subjected to the intense attack by Serbian princeLazar. With the Serbian army in a bad position, Yakub pursued them. While this was happening, his father,Murad I, was assassinated by a Serbian soldier, variously identified as the knightMiloš Obilić. The throne was given to Bayezid with the agreement of the pashas.^{[citation needed]}

In the Ottoman Empire, there was no established heritage system for the crown, and to prevent a possible civil war between himself and Yakub, Bayezid decided to murder his brother. Yakub, on the order of his brother Bayezid, was strangled and killed.^[2] The failed rebellion andresultant civil war thattheir brother had earlier caused may have influenced Bayezid's decision to kill Yakub.^{[citation needed]}

Bayezid brought his brother's body toBursa and buried it in a ceremony. There is no inscription about the tomb located in the northwest of the Yakub Çelebi Mosque inIznik. The tomb of Yakub was buried in the Hüdavendigar Tomb inBursa. Yakub Çelebi has amosque inIznik, a tomb and abath inKeles. This tomb is numbered XIV and it was built towards the end of the century. It has a square plan and there are knitted feet at the corners of the tomb and they are connected to each other with pointed arches. Legs and arches are built with a single row of cut stones and three rows of bricks. A pendant dome based on these covers the tomb.

Yakub Çelebi's Story (Història de Jacob Xalabín), which has an important place in Medieval Catalan literature, is about the adventures of Yakub Çelebi and his murder by Bayezid in the Battle of Kosovo.^[3]

In the 1989 Yugoslav historical dramaBattle of Kosovo, Çelebi is portrayed by Marko Baćović.^[4]

Yakub had two consorts:

• Paleologa princess, daughter of the Byzantine emperorJohn V and his wifeHelena Kantakouzene. She married Yakub in 1386.^[5]
