Civil society and grassroots campaigns are increasingly affecting foreign policy. Some of these campaigns are driven by solidarity groups in the North, who are in solidarity with a struggle in the South. This paper looks at the role of the martyr as a motivating factor to participation in solidarity groups. It looks at the pitfalls of relying on a martyr image, including the fall-out from a controversy between two books: I, Rigoberta Menchú and Rigoberta Menchú and the Story of All Poor Guatemalans.
