The Second Congress in 1987 brought together the EPLF and the Eritrean Liberation Front/Central Leadership (also sometimes referred to as Central Command, CC) in what was called the "Unity Congress". This was the culmination of negotiations over three years which had brought together the two fighting forces in October 1986 under a unified command. On this congress, Isaias Afewerki replaced secretary-general Ramadan Nur. Subsequently, the movement abandoned most of its formerly Marxist–Leninist ideology, in favour of an own revolutionary left-wing concept and a more comprehensive and pragmatic approach to unite all Eritrean nationalists.
