As Brazil celebrates 200 years of independence from Portugal, we look at the 17th-century community of people seeking freedom from slavery in the north-east of the country known as Palmares. It lasted longer and was larger than other settlements of this type and it withstood repeated attempts by European colonialists to destroy it.

So how did Palmares keep going for over a century when so many other communities like it in Latin America vanished after a few years?

To help us sift through what we do know about Palmares, Bridget Kendall is joined by archaeologist Professor Pedro Paulo Funari from the University of Campinas in Brazil; Dr. José Lingna Nafafé, Senior Lecturer in Portuguese and Lusophone Studies at Bristol University; and Dr. Maria Fernanda Escallon, Assistant Professor in the Department of Anthropology at the University of Oregon. The reader is Natan Barreto.
