The city of 'Ar'ar was founded in 1951 (1375 AH), after the construction of the Aramco oil pipeline (Tapline) was completed. It was initially an oil pumping station with a health center and worker housing. Workers at 'Ar'ar were primarily from the regions of Al-Ahsa, Ha'il, Yanbu and Al Wajh.^{[citation needed]} 'Ar'ar got its name from the original oil field that existed before the town, "Field RR", one of many in the country, where it was known by the locals as "R.R." which later became 'Ar'ar.^{[citation needed]} The name 'Ar'ar means juniper in Arabic.

Mustafa Wahbi Al-Tal, better known as Arar (born May 25, 1897 - died 1949), was a Jordanian nationalist, poet, reformist, lawyer, teacher, judge, political agitator, philosopher and a major influencer in the Jordanian national and anti colonial movements. Arar was a pioneer of Jordanian patriotism and a spokesman for the nation's ideals and aspirations. He was known for his nationalist and revolutionary oeuvre and his activism in accordance to it. Rebellious patriotism in Arar's poetry is inextricably tied to his never-ending Don Juanism. As a lover, obsessed by the nostalgia for places that had once quenched his thirst for love, Arar created a quite new type of metaphors and terms of reference to the beloved and to her place in the poet's dream-world. Place-related identity terms referring to the poet's beloved or her close surroundings. And that helped establish a unique Jordanian literary tradition in the Arabic language. His use of dialect, idiom, proverb and other oral formulae helped delineate Jordanian Arabic as a vehicle for literary expression.
