Kaiserreich Greece
http://kaiserreich.wikia.com/wiki/Greece

Greece's independence from Ottoman rule was officially declared in 1829/30, with the Peace of Adrianople, ending the 6th Russian-Turkish War, and the London Protocol.

However, the country was not stabilized until the Danish Prince Wilhelm climbed the Greek throne as Georg I in 1863. Under his rule the country became a parliamentary monarchy with limited powers for the monarch. In 1863 the Ionian Islands were returned by Britain upon the arrival of the new king and in 1881 the Ottoman Empire ceded Thessaly and parts of Epirus to Greece, following the Treaty of Berlin signed three years before.

Despite a defeat against the Ottomans in 1897 when Greece supported the Cretan uprising, the island could - by pressure of the major powers - join the state territory. Macedonia was conquered in the Second Balkans War (1912/13) from Bulgaria, leading to continuously bad relations between the two countries.

During the Weltkrieg King Konstantin I saw to it that his country remained neutral at first, but pressure from the Entente and Prime Minister Eleutherios Venizelos forced him to abdicate in 1917, and Greece joined the war against the Central Powers.

Unfortunately the defeat of Italy allowed Austrian and Bulgarian troops to overrun Greece in 1919, driving out the British forces at Salonica. King Konstantin was returned to the throne of a defeated Greece by the Austrians and Greece was forced to return the territory taken from Bulgaria in 1913, as well as giving Corfu and Kefalonia to Austria itself and Crete to Germany.

Konstantinos was succeeded in 1923 by his son, Georgios II, who had been more pro-British during the war. With the defeat of France and Britain and their later revolutions Greece was left without allies in the west. In the Balkans however it has found friends in the two other defeated nations - Serbia and Romania.

All three share a goal - to reverse their losses from the Great War. However as long as Bulgaria is backed by the victorious Central Powers it seems doubtful that Greece or the other nations can achieve their goal.

Belgrade Pact
http://kaiserreich.wikia.com/wiki/Belgrade_Pact

With what Greece has gone through during WW1, I don't see it having a Social Conservative government. I feel National Populist is a better fit. The hard times the greeks faced after caused a shift in politics to more extreme ideologies.

With the allies losing WW1 the circumstances in my mod do not occur. There is no Ottoman collapse to take advantage of and no proto-Turkey to fight. However, the perceived failure of the "west" is still there. The betrayal. The opportunity to turn "greek" back into a negative word with anti-christian associations is still there.

So a nationalist movement calling for a return to the "glory" days of the roman empire might gain a lot of traction. An ultra-right government determined to take back "roman" lands. First from the Bulgarians and then from the Ottomans.

The greeks have been mobilizing for years and are almost ready to launch their new campaign. If only they can find an ally.
