===The Eastern Roman Empire===

Theodosius II became the eastern emperor in 402. Although personally weak, his mother passed the Theodosian Codes, a collection of Roman laws that had existed since the time of Constantine. Plus, the walls of Constantinople were rebuilt in 413 and defended it successfully for 1,040 years (in 1453 the Turks destroyed the empire and took the city). Christian orthodoxy was enforced, though for around a hundred years weak emperors ruled.

After the buildings built by Constantine were destroyed in riots, he built the Hagia Sophia and fine palaces. Plus, in 529 he passed the Code of Justinian, a collection of Roman laws that made orthodox Christianity the only legal religion, improved justice, and influenced medieval and English laws (English law influenced American law). His general Belisarius conquered North Africa, Sicily, and southern Italy, while Narses took Rome, northern Italy, and southern Spain. But in 568 the Lombards took northern Italy and soon Muhammad's legions took Persia, Israel, Egypt, Syria, and North Africa.
