Byzantine Empire Map: Greatest Extent Under Justinian I (565 AD)

The Zenith of Byzantium

This historical map illustrates the **Byzantine Empire** (Eastern Roman Empire) at its absolute territorial peak in **565 AD**, corresponding with the end of Emperor **Justinian I's** reign. Rendered in imperial purple and gold, it visualizes the results of Justinian's ambitious *Renovatio Imperii*—the restoration of the Empire. The map highlights vast stretches of land surrounding the entire Mediterranean basin under centralized Roman rule for the last time in history.

Key features include the reconquered former Western territories: the Vandal Kingdom in **North Africa** (centered on Carthage), the Ostrogothic regions of **Italy** (governed from Ravenna), and the coastal areas of southern Spain. Major strategic and cultural cities are marked, including **Constantinople**, Antioch, Jerusalem, and Alexandria. A specific indicator points to the location of Justinian's massive new cathedral, the **Hagia Sophia**, in the capital.

Geopolitical Context

Beyond the imperial borders, neighboring powers like the Sassanid Persian Empire, the Franks, and the Visigoths are shown to provide geopolitical context. This map captures a fleeting moment of maximum expansion before subsequent centuries saw significant territorial losses.
