Mansa Sulayman (; ) was mansa of the Mali Empire during the middle of the 14th century. He was the brother of Mansa Musa and succeeded Musa's son Magha as mansa. As mansa, Sulayman continued the diplomatic relations with the Marinid Sultanate that had been initiated by his brother. In 1352 or 1353, Sulayman accused his principal wife, Qasa, of conspiring to overthrow him. Sulayman died 1359 and was succeeded by his son, also named Qasa, who would reign for only nine months. Soon after Sulayman's death, civil war broke out, and Magha's son Jata, who may have been part of the earlier conspiracy to overthrow Sulayman, seized power. Ibn Battuta, an explorer from the Marinid Sultanate, traveled to Mali in 1352 to visit Sulayman's court. His account of his travels, the Tuhfat an-Nuzzar, provides the most detailed known firsthand account of the Mali Empire at its height. Ibn Battuta compared Sulayman unfavorably to his brother, regarding him as a miser in comparison to Musa's renowned generosity. Sulayman is regarded as the last great ruler of the Mali Empire, and his death and the ensuing civil war are considered to mark the end of Mali's golden age. Biography Sulayman was the grandson of Abu Bakr, brother of the Mali Empire's founder Sunjata. Sulayman's brother Musa ruled as mansa for twenty-five years and was succeeded by his son Magha. Magha reigned for only four years and was succeeded by Sulayman. The historian Nehemia Levtzion has suggested that, as the eldest male member of the ruling dynasty, Sulayman was Musa's rightful successor, but Musa passed him over in favor of Magha. Levtzion further suggests that Sulayman may have deposed Magha, and Magha's son Jata may have fled into exile. Sulayman's principal wife and co-ruler was his cousin Qasa. Soon after his accession to the throne, Sulayman received gifts from Abu al-Hasan, the Marinid sultan, which he had sent in response to a delegation Musa had sent him following the Marinid conquest of Tlemcen in 1337. In 1348 or 1349, after the Marinid conquest of Ifriqiya, Sulayman sent another delegation to Abu al-Hasan to congratulate him. The Black Death, which broke out in Europe and North Africa during Sulayman's reign, may have affected Sulayman's diplomatic policy, but it does not seem to have reached Mali itself until some time after 1352–1353. After Abu al-Hasan's death in 1351, Sulayman's court held a memorial feast
