Ghana and its capital of Koumbi Saleh were in decline between 1100 and 1200. The old empire split into several small kingdoms that feuded among themselves. One people, the Mandinka, from the kingdom of Kangaba on the upper Niger River, gradually asserted their dominance over these kingdoms. The Mandinka had long been part of the Ghanaian empire, and the Mandinka and Soninke belonged to the same language group. Kangaba formed the core of the new empire of Mali. Building on Ghanaian foundations, Mali developed into a better-organized and more powerful state than Ghana.

Mali owed its greatness to two fundamental assets. First, its strong agricultural and commercial base supported a large population and provided enormous wealth. Second, Mali had two rulers, Sundiata (soon-JAH-tuh) and Mansa Musa, who combined military success with exceptionally creative personalities.

The earliest surviving evidence about the Mandinka, dating from the early eleventh century, indicates that they were extremely successful at agriculture. Consistently large harvests throughout the twelfth and thirteenth centuries meant a plentiful food supply, which encouraged steady population growth. Kangaba’s geographical location also ideally positioned the Mandinka in the heart of the West African trade networks. Earlier, during the period of Ghanaian hegemony, the Mandinka had acted as middlemen in the gold and salt traffic flowing north and south. In the thirteenth century Mandinka traders formed companies, traveled widely, and gradually became a major force in the entire West African trade.

Mali’s founder, Sundiata (r. ca. 1230–1255) set up his capital at Niani, transforming the city into an important financial and trading center. He then embarked on a policy of imperial expansion. Through a series of military victories, Sundiata and his successors absorbed into Mali other territories of the former kingdom of Ghana and established hegemony over the trading cities of Gao, Jenne, and Walata.

These expansionist policies were continued in the fourteenth century by Sundiata’s descendant Mansa Musa (r. ca. 1312–1337), early Africa’s most famous ruler. Ultimately Mansa Musa’s influence extended northward to several Berber cities in the Sahara, eastward to the trading cities of Timbuktu and Gao, and westward to the Atlantic Ocean. Throughout his territories, he maintained strict royal control over the flourishing trans-Saharan trade. Thus this empire, roughly twice the size of the Ghanaian kingdom and containing perhaps 8 million people, brought Mansa Musa fabulous wealth.

Mansa Musa built on the foundations of his predecessors. Malian society’s stratified aristocratic structure perpetuated the pattern set in Ghana, as did the system of provincial administration and annual tribute. The emperor took responsibility for the territories that formed the heart of the empire and appointed governors to rule the outlying provinces and dependent kingdoms. But Mansa Musa made a significant innovation: in a practice strikingly similar to a system used in both China and France at the time, he appointed royal family members as provincial governors.

In another aspect of administration, Mansa Musa also differed from his predecessors. He became a devout Muslim. Although most of the Mandinka remained animists, Islamic practices and influences in Mali multiplied.

The most celebrated event of Mansa Musa’s reign was his pilgrimage to Mecca in 1324–1325, during which he paid a state visit to the Egyptian sultan. Mansa Musa’s entrance into Cairo was magnificent. Preceded by five hundred slaves, each carrying a six-pound staff of gold, he followed with a huge host of retainers, including one hundred elephants each bearing one hundred pounds of gold. The emperor lavished his wealth on the citizens of the Egyptian capital.

As a result of this pilgrimage, for the first time, the Mediterranean world learned firsthand of Mali’s wealth and power, and the kingdom began to be known as one of the world’s great empires. Mali retained this international reputation into the fifteenth century. Musa’s pilgrimage also had significant consequences within Mali. He gained some understanding of the Mediterranean countries and opened diplomatic relations with the Muslim rulers of Morocco and Egypt. His zeal for the Muslim faith and Islamic culture increased. Musa brought back from Arabia the distinguished architect al-Saheli, whom he commissioned to build new mosques in Timbuktu and other cities. These mosques served as centers for African conversion to Islam.

Timbuktu began as a campsite for desert nomads, but under Mansa Musa it grew into a thriving entrepôt (trading center), attracting merchants and traders from North Africa and all parts of the Mediterranean world. In the fifteenth century Timbuktu developed into a great center for scholarship and learning. Architects, astronomers, poets, lawyers, mathematicians, and theologians flocked there. One hundred fifty schools, for men only, were devoted to Qur’anic studies. The school of Islamic law enjoyed a distinction comparable to the prestige of the Cairo school (see “Education and Intellectual Life” in Chapter 9). The vigorous traffic in books that flourished in Timbuktu made them the most common items of trade. Timbuktu’s tradition and reputation for African scholarship lasted until the eighteenth century.

Moreover, in the fourteenth and fifteenth centuries many Arab and North African Muslim intellectuals and traders married native African women. The necessity of living together harmoniously, the traditional awareness of diverse cultures, and Timbuktu’s cosmopolitan atmosphere contributed to a rare degree of racial tolerance and understanding.

The third great West African empire, Songhai, succeeded Mali in the fourteenth century. It encompassed the old empires of Ghana and Mali and extended its territory farther north and east to become one of the largest African empires in history (see Map 10.2).
