In early Arabian history, su'luk (Arabic: صعلوك, romanized: ṣuʿlūk, plural صعاليك, ṣaʿālīk) was a term that can be translated as brigand, brigand-poet, or vagabond. The sa'alik were mostly individuals who had been forced out of their tribes and who lived on the fringes of society, although some of them maintained ties with their tribes. Some of the sa'alik became renowned poets, writing poetry about the hardships of desert life and their feelings of isolation. Famous sa'alik include Al-Shanfara, Ta'abbata Sharran, and Urwa ibn al-Ward. The sa'alik were most prominent in pre-Islamic Arabia, but persisted during the Umayyad and Abbasid caliphates.
