Once the Portuguese revolution struck in May 1974, it was possible for Namibian youth to leave the country via Angola. Thousands of youth left Namibia between May and December 1974 to join SWAPO abroad, majority ended up serving in the People's Liberation Army of Namibia (PLAN). Youth activist Keshii Pelao Nathanael, was the leader of the internal radical youth inside the country. He and his youth group members orchestrated most of these strikes. He was elected as the founding president of the SWAPO Youth League at the Oniipa Congress in 1974 before going into exile.
