The Anemas (pl. Anemai; Greek: Ανεμάς, -αι), also known as the Anemid dynasty, were an imperial and royal house of Greek origin and of great importance in both the muggle and the wizarding worlds. It was a cadet branch of the Palaiologos dynasty, its founder, Stephanos I Anemas, being a bastard son of Andronikos III Palaiologos. Stephanos was granted the Theme of Nicaea with hereditary privilege, and despite the honours granted onto them by the Palaiologoi emperors, the House of Anemas would ally with the expanding Ottomans, knowing that the Empire would not survive against the Turkish menace.
As such, after the fall of Constantinople, the House of Anemas would maintain control over the area of Nicaea, and in return they gave their full loyalty to the Ottoman Sultan. Shortly after the fall of Constantinople, the head of the Anemas dynasty would marry Eudokia Palaiologina, granddaughter of Constantine XI Palaiologos, uniting the two houses once more, and inheriting the Palaiologoi claims to the Roman throne.
The House of Anemas would eventually betray their Turkish masters, giving way to the Nicaean Revolution, which led to the creation of the independent Kingdom of Nicaea, and the semi-independent Imperial State of Constantinople. The effects of this rebellion would be felt in mainland Greece as well, as the Greeks would also revolt against the Ottoman Empire, eventually allowing the creation of the Kingdom of Greece, which was then given to the King of Nicaea, allowing for the restoration of the Roman Empire in the east.
The House of Anemas originated with Stephanos I, an illegitimate son of Eastern Roman Emperor Andronikos III Palaiologos and Maria Mouzalon. Though Stephanos was illegitimate, his father valued and cared for him, demonstrated by granting him the Theme of Nicaea with hereditary privilege, and protection against political rivals that would seek to raise Stephanos to the throne, which would either end with his successor's political mutilation or that of Stephanos's.
Anemids and the Ottoman Empire
However, the House of Anemas would turn from Constantinople to the Ottoman Sultan, who was quickly advancing into Asia Minor and mainland Greece. Wanting to remain in power, the House of Anemas betrayed the Emperor and swore fealty to the Ottoman Empire, abolishing the Theme of Nicaea, turning it into the Beylik of Anatolia. The Anemids would remain as vassals to the House of Osman for many centuries, relations between the two reaching great heights with both Symeon II Anemas and Sultan Murad IV, who were known to history as great friends.
But the Anemids would also betray their Ottoman masters a few generations later, shortly after Romanos I Anemas became the Bey of Anatolia. Romanos would become the leader of the Nicaean Revolution, which drove the Ottomans from the region of Anatolia and Thrace, paving the way for the foundation of both the Kingdom of Nicaea and the Imperial State of Constantinople, under Romanos I, now King of Nicaea and Co-Regent of Constantinople.
The effects of the Nicaean Revolution would also be felt in mainland Greece, as Ottoman presence there became diminished, which gave way for the Greek War of Independence. Nicaea invaded Ottoman territory in Europe once more, driving the Ottoman Empire from Europe, and establishing the Kingdom of Greece, with Alexios Anemas as the head of state. This recovery of territory led to the formal restoration of the Roman Empire, with Alexios being crowned as Alexios VI in Constantinople.
The House of Anemas remained as the ruling house of the Empire, surviving the Liberal Revolutions and the rise of Communism that plagued western Europe and some countries of Eastern Europe. It briefly became the ruling house of Portugal due to the marriage of Emperor Alexander IV to the Portuguese queen. This however, this lasted only for a year, due to Alexander's death one year after both his and his wife's acclamation as monarchs of Portugal.
In the last decade of the 20th century, the head of house was Henry Anemas, grandson of Alexander IV and his wife.
