19. The Byzantine Empire’s Disastrous Battle

In 634, Arab tribal armies fired up by Islamic zeal erupted from the sparsely populated Arabian Peninsula to simultaneously attack the day’s two superpowers, the Sassanid Persian Empire to the east, and the Byzantine Empire to the west and north. Within two years, the outnumbered Arabs had won a series of brilliant victories that permanently reshaped the Middle East.
The Sassanid Empire fell, while the Byzantine Empire lost its possessions in Syria, Egypt, and North Africa, and got pushed back to today’s Turkey. Of the Arab victories over the Byzantine forces between 634 – 636, the most decisive occurred in August, 636. It was fought along the Yarmouk River, southeast of the Golan Heights, near the intersection of the borders of today’s Syria, Jordan, and Israel.
