The Second Battle of Dongola or Siege of Dongola was a military engagement between early Arab forces of the Rashidun Caliphate and the Nubian-Christian forces of the kingdom of Makuria in 652. The battle ended Muslim expansion into Nubia, establishing trade and a historic peace between the Muslim world and a Christian nation. As a result, Makuria was able to grow into a regional power that would dominate Nubia for over the next 500 years.
