1540 CE to 1683 CE
Mauritania has experienced a slow but constant infiltration of Arabs and Arab influence from the north, beginning with the Arab conquest of the western Maghreb in the eighth century.
The growing Arab presence presses the Berbers, who choose not to mix with other groups, to move farther south into Mauritania, forcing out the black inhabitants.
Most blacks had been pushed to the Senegal River by the sixteenth century.
Those remaining in the north had become slaves cultivating the oases.
After the decline of the Almoravid Empire, a long process of arabization had begun in Mauritania, one that until now has been resisted successfully by the Berbers.
Several groups of Yemeni Arabs who had been devastating the north of Africa turned south to Mauritania.
Settling in northern Mauritania, they had disrupted the caravan trade, causing routes to shift east, which in turn led to the gradual decline of Mauritania's trading towns.
One particular Yemeni group, the Beni Hassan, continue to migrate southward until, by the end of the seventeenth century, they dominate the entire country.
