Great work,but I think you have to do some modifications.Real Greece has all Aegaen Sea, because Rhodos and other islands of south east Aegean-which in this map belongs to Kindom of Italy-were given to Greece (Real) in 1947.Now the AU Hellenian Kingdom,which is Greece as it could be (but it is not,due to mainly political reasons,I do not want any comments about Real Greece) is bigger,because it also has 4 autonomous territories at north which are North Ipiros,North Makedonia,North Thrace and West Thrace (without Istabul),plus all Aegaen Sea.These areas were given after the WWI,in 1920.The fifth territory,Ionia, claimed its indepedence from Hellenian Kingdom in 2 September 1930,but lived until 1955,when all remaining Hellenians forced to leave Ionia.More when I wrote the History of the Hellenian Kingdom. Now for its main enemy(In my AU scemario,with little AU history): From ancient years,much before the Troy War,in Anatolia Penninsular is the Hittite Empire.Hellenians eventually managed to built their Empire,with Alexander the Great,but Persians return and Arabs occupied the South.The Hellenian Empire,(also known as the Byzantine Empire) once reached to Danube River at North and north Egypt at South,shrinked to Europe and Anatolia.Slowly, Hittites returned and with help from Turkic population managed to occupy again Anatolia,while in Europe Serbs and Bulgarians claimed areas.With the Serbs the Empire had always good relationship,but with Bulgarians several wars took place.The southern Empire occupied by Latins and later Hittites until the Revolution of 25 March 1821.With the Balkan Wars and the WWI,The Hellenian Kindom managed to took again some area.
After all in AU everything is possible.
Look odysseus1980, you just take the portion of the map that you need and give me the chart so I can make the necessary changes.
