Principality Overview
A Crusader State
The Principality of Achaea, also known as the Principality of Morea, emerged as one of the principal vassal states of the Latin Empire following the Fourth Crusade's conquest of Constantinople in 1204. It represented a significant Frankish dominion established within the territories of the former Byzantine Empire, specifically the Peloponnese peninsula.
Feudal Monarchy
Functioning as a feudal monarchy, Achaea was characterized by a hierarchical structure of lords and vassals. Its political landscape was shaped by the complex interplay between the Prince, the feudal barons, and the overarching suzerainty of various Western European powers, including the Kingdom of Thessalonica, the Latin Emperors, and later, the Angevin rulers of Naples.
Enduring Legacy
Despite its relatively small size, Achaea was a relatively wealthy and influential principality, lasting for over two centuries. Its unique legal system, the Assizes of Romania, and its distinct cultural blend of French and Greek influences left a notable mark on the history of Frankish Greece and the broader medieval Mediterranean.
Foundation and Early Years
Conquest and Establishment
The principality was formally established in 1205 by William of Champlitte and Geoffrey I of Villehardouin. Undertaking the conquest of the Peloponnese on behalf of Boniface I of Montferrat, King of Thessalonica, their relatively small force achieved a decisive victory against local Greek resistance at the Battle of the Olive Grove of Koundouros. This victory secured their dominance over the Morea, with initial resistance confined to a few isolated forts.
Early Administration
Following the initial military successes, William of Champlitte established a commission to divide the conquered lands into fiefs, adhering to Latin feudal practices. This organizational framework was formalized at a parliament held in Andravida, the principality's early capital. The territory was structured into twelve secular baronies, supported by seven ecclesiastical lordships, reflecting a typical feudal hierarchy.
Succession and Consolidation
William of Champlitte departed for France in 1209 and died en route, leading to his succession by Geoffrey I of Villehardouin. Geoffrey's rule, until his death in 1219, saw the consolidation of the principality's territories and the establishment of its administrative and military structures, laying the groundwork for its future prosperity.
Feudal Organization
Territorial Divisions
The Principality of Achaea was organized into twelve primary secular baronies, each centered around a strategically important castle. These baronies, along with ecclesiastical fiefs granted to bishops and military orders, formed the core of the principality's feudal structure. The Prince's own domain included key territories like Elis, Corinthia, and significant portions of Messenia and Laconia.
The High Court
The secular and ecclesiastical lords constituted the High Court (la Haute Court), presided over by the Prince. This body served as the Prince's advisory council and adjudicated matters concerning feudal law. A Lower Court (la Court de la Borgesie) also existed for common law cases. The feudal lords held significant privileges, including the right to decree capital punishment, and women could inherit fiefs, as Salic Law was not strictly applied.
Government and Administration
Princely Authority
The Prince of Achaea held considerable authority, presiding over the High Court and commanding the principality's military forces. However, the power of the Prince was balanced by the influence of the feudal barons, who enjoyed considerable autonomy within their own territories. The military obligations imposed on vassals were substantial, requiring significant annual service.
Legal and Administrative Fusion
Achaea developed a unique legal framework known as the Assizes of Romania, which synthesized elements of Byzantine and French law. This legal code became influential across other Crusader states. Byzantine administrative titles, such as logothetes and protovestarius, were retained but adapted to Western feudal concepts. The Byzantine pronoia system was also modified, imposing new taxes and duties on the peasant population (paroikoi).
Economic Base
The principality derived its wealth from agricultural exports, including wine, raisins, wax, honey, oil, and silk. Its capital was initially located at Andravida, with the port of Glarentza serving as a crucial commercial hub. The principality's economic stability contributed to its military strength and cultural flourishing.
Historical Trajectory
The Zenith under William II
The mid-13th century marked the zenith of the Principality of Achaea under Prince William II Villehardouin (ruled 1245โ1278). A patron of arts and letters, his court at Glarentza fostered a vibrant literary culture. In 1249, he moved the capital to the newly constructed fortress of Mystras. Despite military successes against the Byzantines, his capture at the Battle of Pelagonia led to territorial concessions and an oath of allegiance to the Byzantine Emperor Michael VIII Palaeologus.
Angevin Suzerainty and Disputes
Following William II's death in 1278, the principality's fate became intertwined with Angevin politics. The Treaty of Viterbo (1267) established Charles I of Anjou as the suzerain, with the principality intended to pass to his son upon Isabella of Villehardouin's marriage. This arrangement, however, led to complex succession disputes and periods of direct Angevin rule through bailiffs, significantly impacting the principality's stability.
Decline and Dissolution
The later centuries were marked by internal feudal conflicts and external pressures, particularly from the Byzantine Despotate of the Morea and later the Ottoman Empire. The principality experienced numerous changes in rule due to disputed claims and political maneuvering. In 1404, the rights were sold to Centurione II Zaccaria, whose rule ended with the Byzantine conquest of the Morea's heartland by 1432. A brief revival occurred in 1453 under John Asen Zaccaria, but it was ultimately short-lived.
Lineage of Princes
Ruling Houses
The Principality of Achaea was ruled by several distinct dynasties, each leaving its mark on the region's history. The most prominent were the House of Villehardouin, known for its cultural achievements, and the various branches of the Angevin dynasty, whose claims and interventions significantly shaped the principality's political trajectory.
In Historical Narratives
Literary Depictions
The history of the Principality of Achaea has inspired historical fiction, offering insights into the lives and conflicts of its inhabitants. Alfred Duggan's novel Lord Geoffrey's Fancy vividly portrays the period from 1257 to 1272, drawing heavily from the Chronicle of the Morea. Angelos Terzakis' novel Princess Isabeau also explores the life of Princess Isabella of Villehardouin, highlighting the dramatic succession struggles.
