Justinian

On 7 April 529, Justinian I published the first instalment of the Corpus Juris Civilis - a codification of Roman law that outlasted the empire, shaped the medieval church, and provided the blueprint for the Napoleonic Code. It is still in use.

On 13th January 532, chariot fans burned half of Constantinople and nearly toppled the Byzantine emperor Justinian. He survived because his wife refused to run. The Hagia Sophia we visit today was built on those ashes.
