They are maternal cousins of the Quraysh tribal confederation and were rivals to them before the rise of Islam in the 7th century CE.

[1][2] There are four clans of Bakr ibn 'Abd Manat:[1][2] Bakr ibn 'Abd Manat collaborated with the Banu Khuza'ah to expel the Jurhum tribe from Mecca after the Jurhum had started unfairly imposing taxes on the pilgrims at the Kaaba.

They have had a few rivalries in the pre-Islamic period, such the conflict of Dhat Naqif which stemmed from the Bakr holding a grudge against the Quraysh due to the takeover of Mecca by Qusayy ibn Kilab.

After the Conquest of Mecca, majority of the Bakr ibn 'Abd Manat converted to Islam.

[2] Descendants of Bakr ibn 'Abd Manat are still alive to this day, and they live not only in the Hijaz region of Arabia, but also in Jordan and Egypt.
