When do militaries undermine democratization?
The recent coup in Niger is but the latest reminder of the importance of militaries in processes of democratization. Historically, soldiers have been the leading cause of democratic collapse. Over 61% of the democracies that died between 1789 and 2008 did so due to a military coup. Today, coups remain a potent threat, ending democratic transitions in Egypt, Thailand, Mali, Myanmar, Guinea, Sudan, Burkina Faso, and Niger, among others.

"American Coup: Wilmington 1898": PBS Film Examines Massacre When Racists Overthrew Multiracial Gov't
American Coup: Wilmington 1898 premieres tonight on PBS and investigates the only successful insurrection conducted against a U.S. government, when self-described white supremacist residents stoked fears of “Negro Rule” and carried out a deadly massacre in Wilmington, North Carolina. Their aim was to destroy Black political and economic power and overthrow the city’s democratically elected, Reconstruction-era multiracial government, paving the way for the implementation of Jim Crow law just two years later. We feature excerpts from the documentary and speak to co-director Yoruba Richen, who explains how the insurrection was planned and carried out, and how the filmmakers worked to track down the descendants of both perpetrators and victims, whose voices are featured in the film.
