William Miller explores the extensive history of medieval Greece from the aftermath of the Fourth Crusade until the Ottoman conquest. The central problem of the narrative is how various foreign powers—Venetians, Franks, and Genoese—established and maintained feudal states across classical lands already inhabited by an ancient Greek population.
The author details the partition of the Byzantine Empire following the capture of Constantinople in twelve hundred and four, tracing the creation of the Duchy of Athens, the Principality of Achaia, and numerous smaller baronies. He analyzes the rigid feudal institutions introduced by Western nobility and shows how these structures interacted with local Greek society, municipal traditions, and the Orthodox Church.
Throughout the work, Miller examines the economic life of these medieval states, highlighting the significance of trade routes, silk production in Thebes, and the persistent threat of piracy in the Aegean Sea. He traces the shifting alliances between the Latin rulers, the restored Byzantine administration at Mistra, and the rising power of the Ottoman Turks.
A major storyline follows the internal divisions among the Greek archontes and the Latin nobility, which left the region vulnerable to external conquest. The narrative details the arrival of new mercenary groups, such as the Catalans and the Navarrese, who carved out their own territories through brute force and political cunning.
The author also covers the complex ecclesiastical dynamics, noting how the friction between the Roman Catholic hierarchy and the local Orthodox population complicated foreign rule. The clergy often acted as a silent force preserving national identity beneath layers of feudal administration.
As the narrative progresses toward the fifteenth century, the unstoppable advance of the Ottoman Empire under Murad the Second and Mohammed the Second forms the dominant focus. The collapse of the defensive Hexamilion wall across the Isthmus of Corinth marks the final phase of Christian resistance in the Peloponnese.
The book concludes with the systematic dismantling of the remaining Frankish principalities and Venetian outposts, culminating in the complete subjugation of the Greek mainland under Turkish rule by fourteen hundred and sixty, while tracing the subsequent fates of the displaced ruling families in Europe.
