Plague of Justinian

In 541, grain ships arrived at the port of Pelusium near Suez in Egypt. These vessels carried infected rats and fleas that would soon carry Yersinia pestis into the heart of the Byzantine Empire. The plague spread from this Egyptian entry point to Constantinople by 542. Procopius recorded the outbreak starting in 541 from that specific port. By 543, the disease had reached every corner of Justinian's empire. It persisted in Northern Europe and the Arabian Peninsula until 549. The contagion moved around the Mediterranean Sea until 544. Roman Egypt served as a significant source for these rodents. Fleas potentially affected by y. pestis were already a known pest control issue there. The Romans imported large amounts of grain from Egypt during this period.

Procopius wrote that the plague killed 10,000 people daily at its peak in Constantinople. He described bodies stacked in the open because there was no room to bury them. Funeral rites went unattended while the entire city smelled like death. John of Ephesus provided another first-hand account of the ravages. Evagrius Scholasticus survived the buboes but lost his wife, daughter, and most servants. He later became a church historian after losing many family members. Procopius noted sufferers experienced delusions, nightmares, fevers, and swellings behind the ears. Some victims fell into coma or died despite treatments. People tried cold baths, powders blessed by saints, and magic amulets when drugs failed. Hospitals received those who could not quarantine themselves effectively.
