Al-Zubayr Rahma Mansur Pasha (Arabic: الزبير رحمة منصور‎; 1830 – January 1913), also known as Sebehr Rahma or Rahama Zobeir, was a slave trader in the late 19th century. He later became a pasha and Sudanese governor. His reputation as a nemesis of General Charles Gordon meant he was bestowed a near-mythic status in the United Kingdom, where he was referred to as "the richest and worst", a "Slaver King" "who [had] chained lions as part of his escort".
