User:Kansas Bear/Ottoman Interregnum

The Ottoman Interregnum, The Ottoman Civil War, (20 July 1402 – 5 July 1413) (Fetret Devri in Turkish) began on 20 July 1402, when chaos reigned in the Ottoman Empire following the defeat of Sultan Bayezid I by the Turco-Mongol warlord Timur. Although Mehmed Çelebi was confirmed as sultan by Tamerlane, his brothers refused to recognize his authority. Civil war was the result. The Interregnum lasted until 5 July 1413, when Mehmed Çelebi emerged as victor in the strife, crowned himself sultan Mehmed I, and restored the empire.

Isa and Mehmed
Civil war broke out among the sons of Sultan Bayezid I upon his death in 1403. His oldest son, Suleyman, with his capital at Adrianople, ruled northern Greece, Bulgaria and Thrace. The second son, İsa Çelebi, established himself as an independent ruler at Bursa and Mehmed formed a kingdom at Amasya. War broke out between Mehmed and İsa, and following the battles of Ermeni-beli and Ulubad, Isa fled to Constantinople and Mehmed occupied Bursa. The subsequent battle at Karasi between Mehmed and Isa resulted in a victory for Mehmed and Isa fleeing to Karaman. Isa was later killed in a bath by agents of Mehmed.

Suleyman enters civil war
Meanwhile the other surviving son of Bayezid, Musa Çelebi, who was captured at the battle of Ankara, was released by Timur into the custody of Yakub of Germiyan Mûsa was freed, after Mehmed made a request for his brother's release. Following Isa's death, Süleyman crossed the straits with a large army. Initially, Suleyman was successful. He invaded Anatolia, capturing Bursa(March 1404) and Ankara later that year.

During the stalemate in Anatolia, which lasted from 1405-1410, Mehmed sent Musa across the Black Sea to Thrace with a small force to attack Suleyman's territories in south-eastern Europe. This maneuver soon recalled Suleyman to Thrace, where a short but sanguinary contest between him and Mûsa ensued. At first Suleyman had the advantage, winning the battle of Kosmidion in 1410, but in 1411 his army defected to Mûsa at Edirne and Suleyman was executed on the orders of Musa. Mûsa was now the ruler of the Ottoman dominions in Thrace.

Mehmed and Musa
Manuel II Palaiologos, the Byzantine emperor, had been the ally of Suleyman; Mûsa therefore besieged Constantinople. Manuel called on Mehmed to protect him, and the Mehmed's Ottomans now garrisoned Constantinople against Musa's Ottomans of Thrace. Mehmed made several unsuccessful sallies against his brother's troops, and was obliged to re-cross the Bosporus to quell a revolt that had broken out in his own territories. Mûsa now pressed the siege of Constantinople. Mehmed returned to Thrace, and obtained the assistance of Stephan, the Serbian King.

The armies of the rival Ottoman brothers met on the plain of Chamurli (today Samokov, Bulgaria). Hassan, the Aga of the Janissaries of Mehmed, stepped out before the ranks and tried to get the troops to change sides. Mûsa rushed towards Hassan and killed him, but was himself wounded by an officer who had accompanied Hassan. Mûsa's Ottomans fought well, but the battle was won by Mehmed and his allies. Mûsa's army fled and he with them until he was shot from his horse and then killed by one of Mehmed's commanders. With Mûsa dead Mehmed was the sole surviving son of the late Sultan Bayezid I and became Sultan Mehmed I. The Interregnum was a striking example of the fratricide that would become common in Ottoman successions.
