Bimbashi Arabic

Bimbashi Arabic ("soldier Arabic", or Mongallese) was a pidgin of Arabic which developed among military troops in Anglo-Egyptian Sudan, and was popular from 1870 to 1920. Bimbashi later branched and developed into three languages: Turku (and its modern descendant Bongor Arabic) in Chad, Ki-Nubi in Kenya and Uganda, and Juba Arabic in South Sudan.
