This article examines the trajectory of the Frente de Libertação de Moçambique (Frelimo), currently the ruling party in Mozambique, focusing on the complex interplay between various factors which contributed to the metamorphoses it has undergone since its founding in 1962. Recent work in the field of international relations and historical sociology has thrown light on the rôle of the state as an administrative-coercive entity constantly cross-pressured by domestic and foreign forces, and acting simultaneously on both fronts in pursuit of advantage. While this scholarship has not focused on ruling parties per se, it is arguable that the standard government versus state dichotomy is of limited analytical value in cases such as Mozambique, where the distinction between party and state remained in practice, until recently, a constitutional nicety. When the ruling party has been institutionalised to the extent of Frelimo, and where the state has become almost an extension of the party, it is the latter that is the key variable in any explanation of political and economic change within society.
