What does it take to create peace? What ideas and values can knit a society back together – or at least make it possible for enemies to lay down their arms and live side by side? Past peace deals offer badly-needed models for our own time, but the process of making peace is often imperfect. And at worst, peace agreements can cement injustice and make future conflict all but inevitable.

This series, moderated by Ideas host Nahlah Ayed, explores four pivotal attempts to make peace over the last three decades, and asks what we can learn from the best - and worst - thinking of the past. The series culminates in an exploration of what it takes to make peace in the fraught context of the 21st century.
