Mauritania's first government was invested in May 1957 and symbolically chose as its new capital Nouakchott, which by design was situated almost exactly between the Senegal River Valley, populated primarily by black farmers, and the Maure stronghold in Adrar. The choice represented a compromise between these two competing areas. It also set the tone for Daddah's approach to Mauritania's political conflicts: compromise and conciliation for the sake of national unity.[8]
