Just prior to independence in 1960, the Trust Territory of Somalia established a national army to defend the nascent Somali Republic's borders. A law to that effect was passed on 6 April 1960. Thus the Somali Police Force's Mobile Group (Darawishta Poliska or Darawishta) was formed. 12 April 1960 has since been marked as "Armed Forces Day". British Somaliland became independent on 26 June 1960 as the State of Somaliland, and the Trust Territory of Somalia (the former Italian Somaliland) followed suit five days later. On 1 July 1960, the two territories united to form the Somali Republic.
