The people of Eritrea, after finding out peaceful resistance against Ethiopia's rule was falling on deaf ears formed the Eritrean Liberation Movement (ELM) which was formed in 1958. The founders of these independence movement were: Mohammad Said Nawud, Saleh Ahmed Iyay, Yasin al-Gade, Mohammad al-Hassen and Said Sabr. ELM members were organised in secret cells of seven. The movement was known as Mahber Shewate in Tigrinya and as Harakat Atahrir al Eritrea in Arabic. On July 10, 1960, a second independence movement, the Eritrean Liberation Front (ELF) was founded in Cairo. Among its founders were: Idris Mohammed Adem, President, Osman Salih Sabbe, Secretary General, and Idris Glawdewos as head of military affairs. These were among those who made up the highest political body known as the Supreme Council. On September 1, 1961, Hamid Idris Awate and his ELF unit attacked an Ethiopian police unit in western Eritrea (near Mt. Adal). This heralded the 30-year Eritrean war for independence. Between March and November 1970, three core groups that later made up the Eritrean People's Liberation Front (EPLF) split from the ELF and established themselves as separate units.
