Jaden left this lucrative job to join the
Southern Sudan People`s Liberation Movement--SPLM in 1963 in the company of Fr.
Saturnino Ohure,
Joseph Oduho and
William Deng Nhial. He was elected President of the movement
Sudan African National Union (SANU) after Joseph Oduho in 1964. He led the movement delegation to the Khartoum round table conference in 1965 and then returned to continue with the struggle. In April 1967, Jaden was elected the president of the Southern Sudan Provisional Government. He moved to
Nairobi, Kenya in 1969 out of fear for his safety.
Gordon Muortat Mayen was his successor as the leader of the
Anyanya. Following the signing of the
Addis Ababa agreement in 1972, Jaden was the first to denounce it as a sell out because his objectives for the struggle were by far much higher. The agreement did not handle the issue of self – determination as at the Khartoum round table conference of 1965, and the agreement was not witnessed by any international observers. Jaden decided to dishonor it and remained in exile. Many southerners tried to convince him to return home and join the Southern Regional Government. He eventually returned to Sudan in 1978 long after
Addis Ababa agreement was signed. He returned an angry man and despite a lot of persuading, he refused to dirty his untarnished political career by participating in the government. In 1983, his rejection of the
Addis Ababa agreement was vindicated when
Gaafar Nimeiry tore the agreement forcing southerners, once again, to take to the bush for the second struggle for the liberation of the Sudan under the late Dr.
John Garang. == Death ==
