The Byzantine Kingdom is a transcontinental Eurasian country. Asian Byzantium, which includes 60% of the country, is separated from European Byzantium by the Bosphorus, the Propontis, and the Dardanelles (which together form a water link between the Black Sea and the Mediterranean). European Byzantium (eastern Thrace or Rumelia in the Balkan peninsula) comprises 40% of the country. The European section, is comprised of Plodivos limiting with Bulgaria and Thracios and Macedonia bordering with Greece and Bulgaria.

The Asian part of the country, is made up of the Anathoray, Opsikion, Mávros, Pontoi and Aigos themes. Anathoray consists of a high central plateau with narrow coastal plains, bordering with Turkey. Pontoi and Aigos limits with the Propontis and the Aegean sea respectively, being Mediterranean climate coastal spaces. Anathoray region is neighbor with the Mávros theme (coastal region limiting between Turkey and the Black Sea) and the Opsikion theme (limiting between Anathoray, Mávros, Pontoi and Constantinople).

The Purple Mantle

The Executive branch is represented by the King (Basileus) who symbolically rules assisted by his Prime Minister (Prothypourgós) who acts as the real Head of Government. The Legislative branch is represented by the βουλή/Voulí Chamber (Parliament) from whom the Executive branch power derives. The Basileus retained the Purple Mantle as a symbol of his royal dignities. The Voulí is divided into two chambers: the High Senate (Noble Aristocracy) and the Low Senate (Bourgeoisie and Commons) and several charges within this senate are attainable through democratic elections in which several Political Parties are involved, being the μπλε or Blue Party (supporting the Upper Classes and the Conservatives) and the πράσινος or Green Party (supporting Lower Classes and the progressive) the most influential of them all. There are also the κόκκινος (Red) and λευκά (White) Parties, all of them descendant originally from the Chariot Racing Teams from the VI Century. The most important elements behind the Prime Minister are the παρακοιμώμενος/Parakoimōmenos (Chief of the ministers) and the σακελλάριος/Sakellarios (Financial Minister).

Byzantine economy is mostly based in trading resources from the surrounding seas (Black Sea and Mediterranean) as well as controlling key elements in the Gulf of Suez Antallagi Port in the XVI Century) to trade resources from the Indians to European Ports.

Since the Industrial Revolution of the XVIII Century, the Kingdom has been focused not only on trading but also in manufacturing consuming goods for internal and mostly external use, as well as ships and some heavy industries.

With the capture of the of the Dalian Region in 1905, Asian trading commerce has become an important element of the Byzantine trading economy.

Armed Forces

The Byzantine Armed Forces are commanded by the "General Staff of the Byzantine Kingdom", currently led by Archistrategos (Chief General) Eupatarius Antonopoulos, who in turn is under the Basileus and Prime Minister command. It's composed of six branches: Army, "Cataphractos", Navy, Air Force, Coast Guard and Gendarmerie (these last two fall under the control of the Ministry of the Interior during peacetime). The Cataphractos (an historical byzantine elite force) are a Heavy Infantry/Cavalry specialized force, ready to be deployed by any means on any terrain/weather, to secure the hostile terrain. It's official motto is "Nobiscum Deus" (God With Us).

Flora and Fauna

For a visitor from Central Europe climatic diversity within Byzantium is quite astonishing. On a somewhat smaller scale all climatic zones of Europe can be found. The Black Sea coast is humid all the year round, with the highest rainfall. South of the Pontic Range rainfall drops abruptly and in Anathoray dry and winter-cold conditions prevail. Approaching the western coast, the climate turns more and more Mediterranean, with mild but very rainy winters and dry, hot summers. Also in regard to edaphic conditions Anatolia’s diversity is astonishingly high. Saline soils are rather common in the driest parts of central Anathoray. In the regions south of Sivas and around Gürün large areas of Gypsum hills are to be found with a very special flora. A further lot of endemics have been described from the extensive serpentine areas in the Western coast (Aigos). Nearly one third or Byzantine plant species (30,6%) is endemic to Byzantium and the nearby Aegean Islands.

Most of the Byzantine demographics is concentrated in urban environments, being Constantinople the most important of them all. The population is increasing by 1.35% each year; with an average population density of 97 people per km². People within the 15–64 age group constitute 67.4% of the total population; the 0–14 age group corresponds to 25.3%; while senior citizens aged 65 years or older make up 7.3%. Life expectancy stands at 71.1 years for men and 75.3 years for women, with an overall average of 73.2 years for the populace as a whole. The main ethnic group recognizes itself as "Hellenic" descendant from the Imperial times, while the rest is divided among Turkish in the south, Slavic/Asian in the east, Caucasian/Hellenic in the west and Caucasian/Panonian in the North.

Byzantine Orthodox Catholic's representation of Christ

Officially, the Byzantine Orthodox Church is the only State-supported religion as well as the most predominant, but other religions are accepted, being the Islamic faith the second more professed. The Byzantine Church has a strongly hierarchical organization similar to the Roman Apostolic Church, being the High Patriarch (Byzantine Pope) its main authority. The Russian Orthodox Church has strong ties with this religious institution.

The Byzantine National Church is also known as the Ecumenical Patriarchate of Constantinople, being known as well as the main subdivision of the Eastern Catholicism, and is subdivided in eight "Eparchies". The liturgical language used is the Medieval Greek.


The main language currently used is by the State is the Greek Koiné. Byzantium is today heterogeneous in linguistic terms, with a large majority of the native population using Byzantine (Updated Medieval Greek) as their first or only language; while Turkish and Bulgarian are also highly present in the Asian and European territories respectively. The Orthodox Church maintains the use of the Medieval Greek.
