<P> The Mali Empire (Manding: Nyeni or Niani; also historically referred to as the Manden Kurufaba, sometimes shortened to Manden) was an empire in West Africa from c. 1230 to 1670 . The empire was founded by Sundiata Keita and became renowned for the wealth of its rulers, especially Musa Keita . The Manding languages were spoken in the empire . It was the largest empire in West Africa and profoundly influenced the culture of West Africa through the spread of its language, laws and customs . Much of the recorded information about the Mali Empire comes from 14th century North African Arab historian Ibn Khaldun, 14th century Moroccan traveller Ibn Battuta and 16th century Moroccan traveller Leo Africanus . The other major source of information is Mandinka oral tradition, through storytellers known as griots . </P> <P> The empire began as a small Mandinka kingdom at the upper reaches of the Niger River, centred around the town of Niani (the empire's namesake in Manding). During the 11th and 12th centuries, it began to develop as an empire following the decline of the Ghana Empire to the north . During this period, trade routes shifted southward to the savanna, stimulating the growth of states . The early history of the Mali Empire (before the 13th century) is unclear, as there are conflicting and imprecise accounts by both Arab chroniclers and oral traditionalists . Sundiata Keita (c. 1214--c. 1255) is the first ruler about whom there is accurate written information (from Ibn Khaldun). Sundiata Keita was a warrior - prince of the Keita dynasty who was called upon to free the Mali people from the rule of the king of the Sosso Empire, Soumaoro Kanté . The conquest of Sosso in c. 1235 gave the Mali Empire access to the trans - Saharan trade routes . Following the death of Sundiata Keita in c. 1255, the kings of Mali were referred to by the title mansa . </P> <P> Sundiata's nephew Mansa Musa made a Hajj pilgrimage to Mecca during the reign of the Mamluk Sultan Baibars (r . 1260--1277). Following a series of usurpations of the throne of Mali, in c. 1285 Sakoura, a former royal court slave, became emperor and was one of its most powerful rulers, greatly expanding the territories of Mali . He made a pilgrimage to Mecca during the reign of Mamluk Sultan An - Nasir Muhammad (r . 1298--1308). Dying on his return, the throne reverted to the descendants of Sundiata Keita . After the reigns of three more emperors, Musa Keita became emperor in c. 1312 . Musa made a famous pilgrimage to Mecca from 1324 to 1326 . His generous gifts to Mamluk Egypt and his expenditure of gold caused gold to be greatly devalued, which gave rise to his fame outside of Mali . In 1337, he was succeeded by his son Maghan I, who in 1341 was deposed by his uncle Suleyman . It was during Suleyman's reign that Ibn Battuta visited Mali . </P> <P> Following this period, a period of weak emperors, conflicts and disunity began in Mali . Ibn Khaldun died in 1406, and following his death there was no continuous record of events in the Mali Empire . It is known from the Tarikh al - Sudan that Mali was still a sizeable state in the 15th century . The Venetian explorer Alvise Cadamosto and Portuguese traders confirmed that the peoples of the Gambia were still subject to the mansa of Mali . Upon Leo Africanus's visit at the beginning of the 16th century, his descriptions of the territorial domains of Mali showed that it was still a kingdom of considerable size . However, from 1507 neighbouring states such as Diara, Great Fulo and the Songhay Empire were eroding the extreme territories of Mali . In 1542, the Songhay invaded the capital city of Niani but were unsuccessful in conquering the empire . During the 17th century, the Mali empire faced incursions from the Bamana Empire . After unsuccessful attempts by Mansa Mama Maghan to conquer Bamana, in 1670 Bamana sacked and burned Niani, and the Mali Empire rapidly disintegrated and ceased to exist, being replaced by independent chiefdoms . The Keitas retreated to the town of Kangaba, where they became provincial chiefs . </P>
