Ghazi Sultan Osman

Description

Osman Gazi, the founder and first Sultan of the Ottoman Empire, was born in Söğüt in 1258, and reliable documentation regarding his youth is quite limited. His father was Ertuğrul Gazi, the bey of a large tribe belonging to the Kayı tribe. According to legend, his mother was Hayme Ana. After Ertuğrul Gazi's death in 1281, Osman Bey, who became the leader of the Kayı tribe in accordance with Oghuz tradition, quickly rallied his forces and began fighting the Byzantine Empire. His first victory was the conquest of Kulacahisar near İnegöl. Then, in 1286, he won the Battle of Domaniç and captured Karacahisar. This marked the beginning of the Ottoman advance, strengthened by the conquest of castles. Thanks to the alliances he forged, numerous raids were conducted in the Sakarya River basin. The founding of the Ottoman Principality dates back to 1299, the period when Osman Bey captured İnegöl. From this date onwards, Osman Bey is considered to have laid the foundations of a new state by declaring independence as the Seljuks weakened. The process of the principality's statehood became clear after the Battle of Koyunhisar (Bapheus) against Byzantium in 1302. This victory is considered the first major engagement in which the Ottomans achieved military superiority over the Byzantines. In the following years, fortresses such as Karahisar, Lefke, Mekece, Geyve, and Gölpazarı were annexed to Ottoman territory. Osman Bey, who inherited the approximately 4,800 km² principality, expanded its territory to 16,000 km² before his death and passed the rule to his son, Orhan Gazi. While opinions differ on the date of his death, 1324 is generally accepted. It is said that he was buried in Söğüt, and after the conquest of Bursa, his remains were transferred to Gümüşlü Kümbet (Gümüşlü Tomb) within Bursa Castle. Thus, Osman Gazi entered history as the founder of the Ottoman Empire, which, from a small frontier principality, would rule three continents for centuries.
