Ertuğrul Gazi son Usman ghazi

Usman Ghazi, also known as Osman I, was the son of Ertuğrul Bey and the founder of the Ottoman Empire. He was born around 1258 and became the leader of the Kayı tribe after his father's death. Usman Ghazi expanded the territory of the tribe and laid the foundation for what would become one of the most significant and powerful empires in history. Under Usman Ghazi's leadership, the Ottomans continued their expansion in Anatolia, consolidating their control over various regions. He established a stable state and laid the groundwork for future Ottoman rulers to build upon. Osman I was the first to adopt the title of "Sultan," which would be used by subsequent Ottoman rulers. The Ottoman Empire, which started as a small tribal entity under Ertuğrul Bey and his son Usman Ghazi, eventually grew into a vast empire that lasted for over six centuries, spanning multiple continents and leaving a profound impact on world history. The empire was ruled by a series of successful sultans, and its peak came during the reign of Suleiman the Magnificent in the 16th century.
