The UN was invited by the then President Kasavubu and Prime Minister and Patrice Lumumba respectively on the 12th of July of the same year, against the secession group backed by the Belgian government. It was in this atmosphere that the first UN peace keeping mission (ONUC) was established and lasted until 1964. Their primary objective was to remove Belgian military presence from the country and ensure internal military stability. However this was did not involve the control of insurrection groups which finally led to Lumumba seeking military aid from the Soviet Union.
