One hundred years on from their first appearance in Leon Trotsky"s Results and Prospects, this is a critical re-evaluation of two key Marxist theories: uneven and combined development, and permanent revolution. It brings together a formidable array of Marxist intellectuals from across the world including Daniel Bensaid, Michael Löwy, Hillel Ticktin and Patrick Bond.Marx saw societies progressing through distinct historical stages – feudal, bourgeois and communist. Trotsky advanced this model by considering how countries at different stages of development influence each other. Developed countries colonise less developed countries and exploit their people and resources. Elsewhere, even as many were kept in poverty, the influence of foreign capital and state-led industrialisation produced novel economic forms and prospects for political alliances and change. The contributors show how, 100 years on from its original publication, Trotsky"s theories are hugely useful for understanding today"s globalised economy, dominated by US imperialism. The book makes an ideal introduction to Trosky"s thinking, and is ideal for students of political theory and development economics.
