This book has asked whether and why Sunni secondary cities in the Middle East have a higher propensity for unrest and ideological-political activism than capital cities. Taking Tripoli in northern Lebanon as a microcosm of the crisis of Sunnism in the broader Middle East, the book tells a story of urban violence in the 20th and early 21st centuries.

Throughout the Tripoli case study, this book identified a feature of secondary cities that I call city corporatism. The root of violence in secondary cities is that these cities often see themselves as united during national turmoil, as a base for one political faction, generally the opposition.

The book identifies four causal mechanisms that jointly explain why urban violence erupts in secondary cities: external meddling; the personal ambitions of local elites; local residents’ willingness to join the fighters; and the existence of competing, or hybrid, Lebanese sovereignties. Each mechanism helps explain why Tripoli has been prone to violence in recent decades.

How did Tripoli, a medium-sized secondary city, become the centre of Lebanon’s anti-imperialist and Arab nationalist protest movement?

Anti-French mobilizations in Tripoli created a unique city corporatism that helped to unite most of the Sunni population politically until the 1970s. When Tripoli was carved out of Syria and attached to the new state of Greater Lebanon in 1920 by the French mandate, the city lost its importance and was demoted to secondary status.

This paved the way for a strong, Arab nationalist city identity in Tripoli, driven by Abdulhamid Karami, a man of religion turned politician. Tripoli’s nationalist identity subsequently morphed into various Islamist trends, involving the bourgeois Islamists, the pro-Palestinian Islamists and the Maoist-turned-Islamist urban poor.

Nationalist and Islamist ideas found a foothold in Tripoli due to the many ties between the city and prominent nationalists and Islamists in Syria. However, Tripoli’s ʿAlawites and Christians contested the Arab nationalist identity of Tripoli as formulated by its Sunni leaders.
