In its heyday the dynasty controlled parts of the Niger River, the Sahara Desert, and the Mediterranean Sea, all major conduits of trade. Almoravid mints struck dinars in many corners of the dynasty’s territory and produced more gold currency than any other empire in the western Islamic lands. Their coinage was highly valued because it was made from West African gold, which was purer than gold from any other known source.
