Sarim al-Din Ibrahim I was Beg of Ramadan from 1354 to 1383.

Ibrahim's father was Ramadan Beg. Ramadan Beg a Turkmen chieftain of the Yüregir tribe and the leader of the Üçok tribal confederation in southern Anatolia.^[1] He was referred to as Ramadan al-Turkmani al-Ujoghi (رمضان التركمانى الاوجعى) by contemporary Arab historians.^[2] Ramadan would eventually be granted the position Emir of the Turkomans by the Mamluk Sultanate following the Dulkadirid leader Zayn al-Din Qaraja's dismissal in 1352 due to a rebellion he joined. Ramadan is thought to have died before June 1354, when Ibrahim arrived in the Mamluk sultan's court in Damascus with a gift of a thousand horses, securing the position his father had received.^[3] According to the Ottoman historian Aşıkpaşazade, Ramadan issued protection for his Armenian subjects upon gaining control of Adana, Tarsus, and Missis.^[4] Further details about his life and reign are unknown as the Ramadanids came into the spotlight with his son Ibrahim's rule.^[5]

Ibrahim later got into an alliance with Qaraja's successor Ghars al-Din Khalil in a campaign to capture Sis from the Mamluks. The Mamluk governor of Çukurova, Timurbay, received a large army in his command from Cairo. Although many of the local Turkoman lords went to Ayas to plead allegiance to him, Timurbay's attempt to raid the region elicited a major backlash that resulted in his defeat and capture in Belen. In 1381, Ibrahim was recognized by the Mamluks, and in 1383, he was given the title na'ib of Adana.^[3]
