The Causes of the Successes of the Ottoman Turks

In Short

Traced through the extraordinary ascent of the Ottoman Empire from a modest Phrygian borderland to the conquest of Constantinople, J. Surtees Phillpotts examines the internal and external forces behind Turkish dominance. The narrative explores how a fractured, stateless group of Oghouz Turks capitalized on Byzantine instability and European disunity. Beyond favorable external circumstances, the book argues that enduring success stemmed from brilliant leadership, a unique military feudalism, and the formidable corps of the Janissaries. It has lasted as a clear-eyed historical analysis of institutional strength and decline.

The Story

The historical trajectory begins amid general anarchy following the fall of the Seljukian dynasty in Asia Minor, leaving scattered Turkish tribes without central organization. Settling in the highlands of Phrygia under Ertogruhl, a clan of Oghouz Turks lays the groundwork for expansion. Ertogruhl's son Othman establishes an independent chieftainship, exploiting the disbandment of Byzantine mountain guards by Emperor Michael to push against imperial borders. Orchan succeeds Othman, expanding territory and uniting tribes to birth the Ottoman state, aided by a crucial twenty-year period of peace overseen by the legislator Alaeddin.

During this domestic consolidation, the Ottomans forge the institutions that guarantee their longevity. Instead of a fragmented feudalism like Western Europe, they institute a centralized military feudalism where all fiefs are held directly of the Sultan. Conquered lands immediately integrate as imperial territory, and war directly funds future expansion through the system of Timarli fief-holders and cavalry service. Simultaneously, the state establishes the Janissaries—a standing infantry corps formed primarily from the children of conquered Christians, stripped of domestic ties and rigorously disciplined like monastic soldiers. This formidable force, combined with religious zeal and absolute obedience to the supreme ruler, provides an unmatched tactical edge.

External circumstances continually favor the rising empire. While European powers remain hopelessly divided by dynastic wars, religious schisms, and mutual animosity—such as the Hundred Years' War or the rift between Rome and Avignon—the Ottomans advance with patient, methodical strategy reminiscent of Roman sovereignty. Amurath extends power into Thrace and Roumelia without meeting united Christian resistance, and later, Mahomet II takes advantage of profound European apathy to execute the historic siege and capture of Constantinople. Throughout successive reigns, extraordinary leaders like Bajazet, Amurath II, Selim, and Solyman the Magnificent leverage these structural and military advantages to drive the empire to its zenith.

The narrative concludes with the inevitable seeds of decline. The absolute centralization of power means the empire's fate rests entirely on the caliber of its rulers. Following the reign of Solyman the Magnificent, succeeding Sultans fail to match their predecessors' genius, while the Janissaries gradually corrupt their own discipline by marrying, engaging in trade, and admitting native Turks into their ranks. As these core institutions decay, the ancient glory of the Crescent dims and obscures, demonstrating that the very structures that built the empire determined its eventual fall.

How It Unfolds

The Anatolian vacuum Following the collapse of the Seljukian dynasty, scattered Turkish tribes roam Western Asia without organized government until a clan under Ertogruhl settles in Phrygia. Othman transforms this settlement into an independent chieftainship, taking advantage of vulnerable Byzantine borders left unguarded by shortsighted emperors.

The twenty-year consolidation Orchan and his legislative coadjutor Alaeddin secure a rare period of internal peace to organize the burgeoning state. During this era, they establish a centralized feudal system and lay the groundwork for a disciplined standing army.

The institution of the Janissaries To solve the problem of unruly native troops, the state creates an elite infantry corps recruited from Christian children taken in war. Trained under strict, monastic conditions with absolute loyalty to the Sultan, these proselytes become the invincible backbone of every major campaign.

The paralysis of Christendom As Ottoman forces push into Europe and Thrace, Western powers remain paralyzed by internal conflicts, rival popes, and bitter enmities. This pervasive disunity prevents any unified coalition from arresting the steady expansion of the Sultan's dominion.

The fall of Constantinople At the crowning point of their success, Mahomet II leads the final siege against the Byzantine capital amid total European indifference. Backed by famed artillery and the unmatched valour of the Janissaries, the Ottomans breach the city and secure Eastern Rome.

The apex and subsequent decline Under Solyman the Magnificent, the empire reaches its absolute zenith, governing dozens of diverse races through efficient administration and advanced legislation. However, the subsequent lack of capable rulers and the decay of Janissary discipline ultimately lead to the dimming of Ottoman glory.

The People

Othman initiates the dynasty, wanting security and expansion for his wandering clan against the backdrop of Anatolian chaos. Standing in his way are fragmented local rivals and the Byzantine Empire, though he successfully navigates these obstacles to establish an independent chieftainship. He leaves behind a legacy of foundational customs adopted by his successors.

Alaeddin, the brilliant legislator and coadjutor to Orchan, seeks institutional stability for the young state. Overcoming the inherent instability of rapid Asiatic conquests, he devises a centralized feudal framework and initiates the standing army, leaving the empire with enduring administrative stability.

Amurath pursues territorial expansion into Europe, seeking to subdue the Sclavonic tribes of Servia and Bosnia. Confronted by hostile regional forces and fierce regional resistance at battles like Kossova, he overcomes them by utilizing the newly formed Janissary corps, ultimately extending his borders and paving the way for future dominion.

Mahomet II wants the definitive conquest of the Byzantine capital and the consolidation of Eastern Rome under Ottoman rule. Standing in his way is the heroic, albeit desperate, resistance of the last Greek Emperor and the enervated Byzantines. He ends up triumphant, utilizing disciplined troops and famed artillery to capture Constantinople.

Solyman the Magnificent seeks the zenith of imperial greatness, governing an empire spanning nearly fifty million subjects. Facing powerful contemporary sovereigns across Europe and Asia, he relies on his own exceptional genius and legacy institutions to cement his status as a master lawgiver, leaving the dynasty at its absolute historical peak.

In Its Own Voice

Describing the unique nature of the Ottoman standing army and its monastic discipline, the author emphasizes how stripped these soldiers were of domestic distractions.

They had no homes in which they could be pampered with Oriental luxury.

Detailing the absolute power and centralization of the realm, the text highlights the unique role played by men elevated from servitude.

“a servile class, an artificial people, were raised by the discipline of education to obey, to conquer, and to command.”

Reflecting on the overarching philosophy of governance, the author notes how the empire's expansion mirrored ancient imperial might.

In its slow and cautious advance, in the gradual organization of conquered provinces, in the unswerving patience which waited always for the fittest opportunity, it bore no faint resemblance to the stately march of Roman sovereignty.

What It's Really About

The book investigates the mechanics of imperial rise and structural longevity, asking why certain dynasties collapse into ephemeral sparks while others endure. Phillpotts argues that raw military aggression is insufficient without deliberate institutional design. The central theme explores the interplay between absolute despotism and enlightened administration—demonstrating how a state can compensate for the inherent risks of single-ruler governance through rigorous educational systems, centralized feudalism, and meritocratic integration of outsiders. It questions how a society built by nomadic warriors successfully absorbed diverse populations through a combination of pragmatic religious toleration and absolute military subordination. Underneath the historical recounting lies a sharp examination of how institutional decay inevitably mirrors institutional birth.

Why Read It Today

History enthusiasts and readers fascinated by the mechanics of statecraft will find much to admire in this compact, analytical study. Reading it feels akin to sitting down with an erudite nineteenth-century scholar who values logical clarity over dramatic embellishment, moving briskly through centuries of geopolitical shifts without unnecessary padding. What stays with you is the sharp realization of how institutional engineering—such as the calculated integration of renegades and the meticulous structure of the Janissaries—can sustain a civilization far beyond the limits of ordinary fortune. Modern readers should note, however, that the text reflects nineteenth-century historiographical conventions, occasionally adopting period assumptions about civilization and barbarism, and dense academic footnotes referencing Gibbon or Ranke can interrupt the narrative flow. Despite these formal period constraints, those seeking a rigorous, unvarnished look at the structural foundations of the Ottoman state will find a rewarding and intellectually stimulating experience.
