File:Greece in 1278.svg

SVG base from File:Greece in 1210V1.svg; based on the original political map by William Miller (1908), with changes and corrections to account for newer scholarship:

• The Ghisi brothers are shown as independent of the Duchy of Naxos (cf. Setton, Kenneth M. (1976). The Papacy and the Levant (1204–1571), Volume I: The Thirteenth and Fourteenth Centuries, p. 19 note 78)
• Epirus and Thessaly are distinguished from the Byzantine Empire
• Byzantine territories in the Morea are based on Bon, Antoine (1969). La Morée franque. Recherches historiques, topographiques et archéologiques sur la principauté d’Achaïe, although the exact boundaries are uncertain
• Gardiki, Gravia, Sideokastron, and Zetouni are shown under Athens, since they were ceded in 1275 by John I Doukas of Thessaly (cf. Fine, John Van Antwerp (1994). The Late Medieval Balkans: A Critical Survey from the Late Twelfth Century to the Ottoman Conquest, p. 188)
• Area around the Pagasetic Gulf shown in Byzantine hands per Nicol, D. M. (1962). "The Greeks and the Union of the Churches the Report of Ogerius, Protonotarius of Michael VIII Palaiologos, in 1280". Proceedings of the Royal Irish Academy. Section C: Archaeology, Celtic Studies, History, Linguistics, Literature. 63: 1–16, and the existence of a Byzantine governor in the area in 1276.
