What is "zir'in"

Zir'in (, also spelled Zerein) was a Palestinian Arab village of over 1,400 in the Jezreel Valley, located north of Jenin. Identified as the ancient town of Yizre'el (Jezreel), it was known as Zir'in during Islamic rule, and was near the site of the Battle of Ain Jalut, in which the Mamluks halted Mongol expansion southward. Under the Ottomans, it was a small village, expanding during the British Mandate in the early 20th century. After its capture by Israel in 1948, Zir'in was destroyed.
