Civilization V Customisation Wiki

Byzantium led by John II is a custom civilization mod by DuskJockey, with contributions from DJSHenninger and danrell.

This mod requires Gods and Kings and Brave New World.



Existing for more than 1,000 years, the Byzantine Empire, centered in the legendary city of Constantinople, was initially formed as the eastern seat of power for the mighty Roman Empire which was split into Eastern and Western. Located on the crossroads of Europe, Asia and Africa, Constantinople easily became the world's trading center and the primary trade hub in the region. Due to its strategic location, and as the center of Orthodox Christianity, Constantinople flourish despite the internal conflicts that led to the decline of Rome in the west. Inspired by number of memorable rulers, the Byzantine Empire was also a source of great cultural growth along the eastern Mediterranean, its affluence allowing for grand displays of art, architecture, science, religion, and music. The Byzantine Empire's official language was first the Latin and later changed to Greek, which was the lingua franca in Eastern Mediterranean.

John II[]

John II Komnenos "the Handsome" was emperor of the Byzantine Empire from 1118 to 1143 AD. John, almost constantly on campaign throughout his reign, would continue the military successes of his father Alexios I with significant victories in the Balkans, Armenia, and Asia Minor. The Byzantine Empire, thus, regained something of its former sparkle and the respect of its rivals across the Mediterranean.

Dawn of Man[]

"The Roman people wait with bated breath for your command, John II Komnenos, emperor of Byzantium! Chosen as the successor of the highly energetic Alexios I, you would ascend the throne amid the schemes of the imperial court, spearheaded by your ambitious sister Anna. By pardoning these conspirators you would demonstrate the clemency and piety that would mark your just reign. Your virtuous rulership would not go unrewarded, as God would grant you boundless strength to continue your father's quest to reunite the tattered remnants of the Byzantine empire. Your military campaigns would blot out the perfidious Pechenegs and win back for the empire her heartlands. Through your greatness in arms and in character, the empire of the Romans regained its former luster, and Constantinople its title as 'queen of cities'.
