Battle of Dhu Qar
The Battle of Dhu Qar (Arabic: يوم ذي قار), also known as the War of the Camel's Udder, was a pre-Islamic battle fought between Arab tribes and the Persian Sasanian Empire in Southern Iraq between 604 and 611 AD. The battle is remembered as a turning point in Arab-Persian relations, and a blow to Persian control over Eastern Arabia, though the battle may have been no more than a skirmish. The battle is sometimes understood as part of a more prolonged Arab rebellion against the Persians, which culminated in the early Muslim conquests a few decades later.
