Bayezid I, also known as Bayezid the Thunderbolt, was the sultan of the Ottoman Empire from 1389 to 1402. He adopted the title of Sultan-i Rûm, Rûm being the Arabic name for the Eastern Roman Empire. In 1394, Bayezid unsuccessfully besieged Constantinople. He defeated the Crusaders at the Battle of Nicopolis in what is now Bulgaria in 1396. He was later defeated and captured by Timur at the Battle of Ankara in 1402 and died in captivity in March 1403, which triggered the Ottoman Interregnum.
Mehmed I, also known as Mehmed Çelebi or Kirişçi, was the sultan of the Ottoman Empire from 1413 to 1421. The fourth son of Sultan Bayezid I and Devlet Hatun, he fought with his brothers over control of the Ottoman realm in the Ottoman Interregnum (1402–1413). Starting from the province of Rûm he managed to bring first Anatolia and then the European territories (Rumelia) under his control, reuniting the Ottoman state by 1413, and ruling it until his death in 1421. Called "The Restorer," he reestablished central authority in Anatolia, and he expanded the Ottoman presence in Europe by the conquest of Wallachia in 1415. Venice destroyed his fleet off Gallipoli in 1416 as the Ottomans lost a naval war.
The 1410s decade ran from January 1, 1410, to December 31, 1419.
Year 1411 (MCDXI) was a common year starting on Thursday of the Julian calendar.
The Ottoman Interregnum, or the Ottoman Civil War, was a civil war in the Ottoman Empire between the sons of Sultan Bayezid I following their father's defeat at the hands of Timur in the Battle of Ankara on 20 July 1402. Although Timur confirmed Mehmed Çelebi as sultan, Mehmed's brothers İsa Çelebi, Musa Çelebi, Süleyman Çelebi, and later, Mustafa Çelebi, refused to recognize his authority, each claiming the throne for himself. This resulted in civil war. The Interregnum would last a little under 11 years, culminating in the Battle of Çamurlu on 5 July 1413, when Mehmed Çelebi emerged as victor, crowned himself Sultan Mehmed I, and restored the empire.
Çandarlızade Ali Pasha was the grand vizier of the Ottoman Empire from 1387 until 1406, first under sultan Murad I, then sultan Bayezid I and, during the Ottoman Interregnum, Süleyman Çelebi.
Vuk Lazarević was a Serbian Prince and the younger son of Prince Lazar of Serbia and Princess Milica Nemanjić. He was executed on 6 July 1410.
Mûsâ Çelebi was an Ottoman prince and a co-ruler of the empire for three years during the Ottoman Interregnum.
The Battle of Kosmidion occurred on 15 June 1410, during the Ottoman Interregnum, and was fought between the forces of the rival brothers, Musa Çelebi and Süleyman Çelebi, at Kosmidion just outside the land walls of Constantinople.
Süleyman Çelebi was an Ottoman prince and a co-ruler of the Ottoman Empire for several years during the Ottoman Interregnum. There is a tradition of western origin, according to which Suleiman the Magnificent was "Suleiman II", but that tradition has been based on an erroneous assumption that Süleyman Çelebi was to be recognised as a legitimate sultan.
İsa Çelebi was an Ottoman prince and a co-ruler of the empire during the Ottoman Interregnum.
Juneyd or Junayd Bey was the last ruler (bey) of the Aydınid principality in what is now central western Turkey. His exact relationship with the Aydınid dynasty is unclear. His father was a long-time and popular governor of Smyrna under the Ottoman sultan Bayezid I. This allowed Junayd to consistently rely on the loyalty of the area's populace.
The siege of Constantinople of 1411 occurred during the Ottoman Interregnum, or Ottoman Civil War,, when chaos reigned in the Ottoman Empire following the defeat of Sultan Bayezid I by the Central Asian warlord Timur. Although Mehmed Çelebi was confirmed as sultan by Timur after the Battle of Ankara, his brothers İsa Çelebi, Musa Çelebi, Süleyman Çelebi, and later, Mustafa Çelebi, refused to recognize his authority, each claiming the throne for himself. A civil war was the result. The Interregnum lasted until the Battle of Camurlu on 5 July 1413, when Mehmed Çelebi emerged as victor in the strife, crowned himself sultan Mehmed I, and restored peace to the empire.
The Battle of Ulubad was fought sometime between 9 March and early May 1403 at Ulubad between the rival sons of the Ottoman Sultan Bayezid I, Mehmed Çelebi and İsa Çelebi, during the first stages of the civil war known as the Ottoman Interregnum. The battle was a major victory for Mehmed, who occupied the Ottoman capital, Bursa, and became master of the Ottomans' Anatolian domains. İsa fled to the Byzantine capital Constantinople, while Mehmed proceeded to formally lay claim to the succession of Bayezid by an enthronement ceremony in Bursa, and by having his father's body buried there. By 18 May 1403, however, İsa returned to Anatolia with an army provided by their oldest brother, Süleyman Çelebi, ruler of Rumelia. İsa was again defeated and eventually killed after a series of battles by September.
The Treaty of Gallipoli, concluded in January or early February 1403, was a peace treaty between Süleyman Çelebi, ruler of the Ottoman territories in the Balkans, and the main Christian regional powers: the Byzantine Empire, the Republic of Venice, the Republic of Genoa, the Knights Hospitaller, and the Duchy of Naxos. Concluded in the aftermath of the Battle of Ankara, while Süleyman tried to strengthen his own position in the succession struggle with his brothers, the treaty brought major concessions to the Christian states, especially the Byzantines, who regained lost territories and achieved a position of nominal superiority over the Ottoman ruler. Its provisions were honoured by Süleyman as well as by Mehmed I, the victor of the Ottoman succession struggle, but collapsed after Mehmed's death in 1421.
The Battle of Kırkdilim was fought in July 1391 or 1392 between the Ottoman şehzade Ertuğrul and Kadi Burhan al-Din, ruler of northeastern Anatolia. The details of the battle are debated: Burhan al-Din's court poet Ibn Ardashir presents Bayezid's campaign being ended by a major victory for his master, which temporarily halted Ottoman expansion in Anatolia, but the contemporary letters of Manuel II Palaiologos, who accompanied Bayezid on his Anatolian campaigns, contain no indications of a major clash, and point to the expedition having been an Ottoman success overall.
The Battle of İnceğiz was fought sometime in late 1411 or early 1412 near Constantinople between the rival sons of the Ottoman Sultan Bayezid I, Mehmed Çelebi and Musa Çelebi, during the final stages of the civil war known as the Ottoman Interregnum.
The Treaty of Selymbria was an agreement concluded on 3 September 1411 between the Republic of Venice and the Ottoman prince Musa Çelebi, ruler of the European portion of the Ottoman Empire (Rumelia), at Selymbria. The treaty largely repeated previous agreements between Venice and Ottoman rulers, and recognized the possessions of the Republic in Greece and Albania.
Mihaloğlu Mehmed Bey was a member of the Mihaloğulları family and one of the most important frontier warlords of the Ottoman Balkans during the last phase of the civil war of the Ottoman Interregnum (1403–1413), and during the early years of Murad II's reign.
The Battle of Edirne occurred on 11 July 1410, during the Ottoman Interregnum, and was fought between the forces of the rival brothers, Musa Çelebi and Süleyman Çelebi, outside the Ottoman capital, Edirne.
