The Foundation of the Ottoman Empire; A History of the Osmanlis Up to the Death of Bayezid I (1300-1403)
1916
Published in 1916, this was among the first rigorous English-language histories of the Ottoman Empire's birth. Herbert Adams Gibbons wrote from direct experience in the region, drawing on sources and observations unavailable to most Western scholars of his era. The book traces the remarkable transformation of a obscure Anatolian beylik into a territorial power between 1300 and 1403, chronicling how Osman I leveraged the chaos left by Byzantine decline and Mongol invasions to establish a small but viable state. The narrative follows his successor Orkhan, who built the first Ottoman standing army and secured Byzantine territories through strategic marriages. By the time of Bayezid I, the Ottomans had become the dominant power in Asia Minor and laid siege to Constantinople itself. Gibbons paints a portrait of state formation in real time, showing how a tribal confederacy became something far more dangerous: an empire with institutions, ambitions, and a sense of divine destiny. For students of medieval history, Ottoman studies, or the collapse of Byzantium, this remains a foundational text that illuminated a civilization often overlooked by Western historiography.

Key Themes
- Religious Conversion and Identity
- The transformation of the Osmanlis from pagans to Muslims under Osman, and their policy of religious tolerance that enabled the assimilation of Christian populations. The book argues that conversion to Islam was the key to Ottoman success.
- Empire Building vs. Raiding
- Gibbons emphasizes that the Osmanlis were empire-builders, not mere raiders like other Turkic peoples. Their success came from patient assimilation of conquered peoples rather than destruction and plunder.
- East vs. West Religious Conflict
- The deep animosity between Eastern Orthodox and Roman Catholic Christianity prevented effective Christian unity against the Ottomans. This religious schism was exploited by Ottoman rulers and aided their conquests.
