The historic oasis area shows its first archeological evidence of settlement beginning about 3500 BC. It was known by other names, such as Al-Khatt, immortalized in the poetry of `Antara ibn Shaddad, Tarafa ibn Al-`Abd, Bashar ibn Burd (in his famous Ba'yya), and others. The word "Khatty" became the preferred "kenning" for "spear" in traditional poetic writing until the dawn of the modern era, supposedly because the region was famous for spear making, just as "muhannad" ("of India") was the preferred kenning for "sword".

The Buyids of western Persia raided Qatif in 988. From 1071 until 1253 the Uyunids ruled the region first from the city of "al-Hasa" (predecessor to modern Hofuf) and later from Qatif. In 1253 the Usfurids rose from Al-Hasa and ruled during the struggle of Qays with the Hormuz for control of the coast. Probably at about this time, Qatif became the main port for the mainland surpassing 'Uqair in importance for the trade and thus became the capital of the Usfurids. Ibn Battuta, visited Qatif in 1331 and found it a large and
