A dervish, darvesh, or darwīsh in Islam is a member of a Sufi fraternity (tariqah), or more narrowly a religious mendicant, who chose or accepted material poverty. The latter usage is found particularly in Persian and Turkish (derviş) as well as in Tamazight (Aderwic), corresponding to the Arabic term faqīr. Their focus is on the universal values of love and service, deserting the illusions of ego (nafs) to reach God. In most Sufi orders, a dervish is known to practice dhikr through physical exertions or religious practices to attain the ecstatic trance to reach God. Their most popular practice is Sama, which is associated with the 13th-century mystic Rumi. In folklore and with adherents of Sufism, dervishes are often credited with the ability to perform miracles and ascribed supernatural powers. Historically, the term Dervish has also been used more loosely, as the designation of various Islamic political movements or military entities.

The Battle of Abu Klea, also known as the Battle of Abu Tulayh, took place between 16 and 18 January 1885, at Abu Klea, Sudan, between the British Desert Column and Mahdist forces encamped near Abu Klea. The Desert Column, a force of approximately 1,400 soldiers, started from Korti, Sudan on 30 December 1884; the Desert Column's mission, in a joint effort titled the "Gordon Relief Expedition", was to march across the Bayuda Desert to the aid of General Charles George Gordon at Khartoum, Sudan, who was besieged there by Mahdist forces.
