Next city will be Oualata or Walata (also Biru in 17th century chronicles) is a small oasis town in south east Mauritania that was
important in the thirteenth and fourteenth centuries as the southern terminus of a trans-Saharan trade route.
History
Oualata is believed to have been
first settled by an agro-pastoral people akin to the Soninke who lived along the rocky promontories of the Tichitt-Oualata and Tagant cliffs of Mauritania.
There, they built what are among the oldest stone settlements on the African continent.
The collapse of the empire of Ghana in 1224 led refugees from Awdaghast to found a new city in the small village of Birou. The new city was called Oualata and contained
immigrants from several ethnic groups including Berbers, Islamized Soninke and Massufa nomads. The Berbers were the religious monks as well as merchants whilst the Soninke provided craftsmen and the Massufa nomads acted as caravan guides. T
he rise of the empire of Mali and the subsequent shift of political power to the south strengthened the position of Oualata as a regional centre and as a terminus for trans-Saharan caravans. The main partner for this desert trade was the city of Sijilmassa in southern Morocco from which goods would be traded further north to Fez and Tlemcen in Algeria.
