The Latin Empire of Romania (French: Empire latin de Roumanie; Greek: Λατινική Αυτοκρατορία της Ρωμανία) is a Frankish empire in Southeastern Europe. Ruled by Emperor William de la Roche, the Latin Empire was re-established as a landed nation in the Treaty of Venice, largely through the efforts of the Principality of Achaea.

The Empire, which is based in southern Greece, is comprised of the following entities:

  • Principality of Achaea;
  • Duchy of Athens;
  • Despotate of Epirus;
  • Kingdom of Albania;
  • Kingdom of Thessalonica;
  • County of Caria;
  • Duchy of the Archipelago; and
  • County Palatine of Cephalonia and Zakynthos.

The official religion of the Latin Empire of Romania is Roman Catholicism. With the Fourth Crusade, a number of ecclesiastic positions were created in newly-conquered lands - the most influential of which was the Latin Patriarch of Constantinople, displacing the Eastern Orthodox Patriarch.

With the restoration of Constantinople to the Byzantines, the Latin Patriarch became a titular see based out of Rome. However, with the restoration of the Latin Empire under Emperor Florent, the Latin Patriarch - then Nicholas of Thebes - was invited to return to Romania.

Foreign Relations

The Latin Empire is a leading member of both the Latin League (dating back to 1343) and the Holy League (dating back to 1353). In addition, it maintains good relations with the vast majority of the Catholic world - it can ill-afford to sour relations with potential benefactors. Relations with Orthodox and Muslim neighbors, however, have traditionally been strained.

  • Positive () Relations
    • Hungary - Allies and royal marriage; aid against Serbia.
    • Venice - Pursuant to the Treaty of Venice (1308), the Latin Empire and Venice are officially allied. This alliance was initially aimed at Genoa (which has since been conquered) and the Byzantine Empire. In addition to the alliance, there are deep trade relations between Venice and the Latin Empire.
    • Aragon - During the War of the Sicilian Vespers and subsequent Aragonese-Neopolitan War, Achaea (the predecessor of the Latin Empire) was a tributary of Aragon, after having abandoned Naples. Aragon's aid was necessary in procuring lands across the region for the Latin Empire, and therefore the Empire looks upon Aragon with favor.
  • Neutral () Relations
    • Neopatria - These formerly-Byzantine lands were conquered by the Catalan Company. The Duchy of Neopatria is a member of the Latin League with the Empire, but other than this mutual-defensive pact, it remains to be seen how the future relations will play out.
    • Byzantine Empire - Following an extended period of war dating back to the Fourth Crusade, a rare rapproachment was brokered in the lead up to the Crusade of the Holy League. Latin prince Richard and Byzantine princess Irene were betrothed on terms favorable to the Latin Empire. It remains to be seen whether the two nations grow closer or further apart.
  • Negative () Relations
    • Anatolian Muslim Beyliks - Following the conquest of Caria (formerly Mentese) by Achaea, and exacerbated more recently by the Crusade of the Holy League against the Ottomans, relations with the Beyliks has been hostile. While the beyliks were originally seen as a counterbalance against the Byzantines, this has decidedly changed once Turks first set foot in Europe.
    • Serbia - Following the aggressive and expansionist attack on Latin Romania by Tsar Stephan of Serbia, in which the Empire defended itself, relations have been quite hostile. In the meanwhile, the Latin Empire has fortified and defended its border with Serbia.
