[1] In some sources relating the Arab conquest of Syria, it is mentioned that the last army the Byzantine Empire set up in the region took up position near Jalin before the crucial Battle of the Yarmuk in 635.

The battle took place west of Jalin and led to the catastrophic defeat of the Byzantine army.

At Jalin, the inhabitants cultivated grapes and vegetables in nearby vineyards and gardens.

Jalin's population increased significantly in the mid-20th century with families moving there from the Beisan Valley, the Syrian steppe and the Butayha area of the Golan Heights.
