This review essay critically examines the evolution of scholarly literature on Brazil's Partido dos Trabalhadores since the PT's founding in 1980. We periodise the relevant literature into four phases, examining the foundation of the PT, the party's early experience in subnational government, its transformation and moderation in the late 1990s, and finally its experiences in national government since capturing the presidency in 2002. After detailing strengths and weaknesses of this research, we also examine the trajectory of the PT in light of recent comparative work on the so-called ‘left turn’ in Latin America. We conclude by offering an agenda for future research on the PT.
