for him in 1352, which was attended by the Moroccan explorer Ibn Battuta, who had recently arrived in Mali. Two months later, during Ramadan, Ibn Battuta complained to Sulayman about the meagreness of the reception gift he had initially received from him, and Sulayman arranged for Ibn Battuta to receive lodgings and a gift of gold. While Ibn Battuta was in Mali, Sulayman imprisoned his principal wife Qasa and replaced her with one of his other wives, Banju. Unlike Qasa, Banju was not of royal blood. Facing criticism from his court, Sulayman accused Qasa of conspiring to overthrow him with an exiled member of the royal family named Jatil, who may have been Magha's son. Sulayman obtained a confession from one of Qasa's slaves, and his court pronounced a death sentence on Qasa, who sought sanctuary with the khatib. Qasa's fate is not recorded. Sulayman continued to pursue diplomacy with the Marinid Sultanate, and was preparing another delegation bearing gifts for the sultan when he died. He was succeeded by his son Qasa. Qasa reigned only nine months. Soon after Sulayman's death, civil war broke out, and Sulayman's great-nephew Jata, son of Magha—possibly the same as the Jatil who had conspired to overthrow Sulayman in 1352–1353—seized power. Dates The dates of the beginning and end of Sulayman's reign are not precisely known, and the evidence provided by the available primary sources is contradictory. According to Ibn Khaldun, a caravan bearing gifts sent by Mansa Jata soon after he took power arrived in Fez in December 1360 or January 1361. As at least nine months must have passed between Sulayman's death and Jata sending the caravan, in order to fit Qasa's reign, Sulayman's death must have occurred no later than early 1360. Maurice Delafosse regarded Sulayman's reign as having ended in 1359. Djibril Tamsir Niane regarded Sulayman's reign as having ended in 1358 or 1359. In a 1963 paper, Nehemia Levtzion regarded Sulayman as having died at the beginning of 1360, but elsewhere, he and John F. P. Hopkins regarded Sulayman as having died in about 1358–1359. John Hunwick and David Conrad both used the 1360 date. According to Ibn Khaldun, Sulayman reigned for 24 years. If Sulayman died in 1360, this would indicate he became mansa in approximately 1336, which is the year Delafosse and Niane regarded Sulayman's reign as beginning. However, this is contradicted by Ibn Khaldun's indication that
