Today we commemorate Emperor Justinian, Christian Ruler and Confessor of Christ. Emperor of the Eastern Roman Empire from AD 527 to AD 565, Justinian oversaw a renaissance during which an empire long in decline briefly resurged. Under his leadership, the Roman Empire retook North Africa, Italy, and Spain. However, Justinian is primarily remembered for his codification of Roman law (a basis of many systems to this day) and his staunch defense of and support for the Christian faith.
