Liberation movement
After the Portuguese Carnation Revolution in 1974, Simango returned to Mozambique and established a new political party, the National Coalition Party (PCN), in the hope of contesting elections with FRELIMO. He was joined in the PCN by other prominent figures of the Liberation movement and the FRELIMO dissidents: Paulo Gumane and Adelino Gwambe (also a founder member of FRELIMO), Father Mateus Gwengere and Joana Simeao.
