Governor's Lecture Series - "The House of War: The Struggle Between Christendom and the Caliphate"
Date: Wednesday 28th January 2026
Join Sir Simon Mayall as he guides you from Caliph Umar’s 7th‑century capture of Jerusalem to the fall of the Ottoman Empire after the First World War, highlighting some of the most consequential battles in global history.
Uncover the narrative of a centuries‑long contest for political, military, ideological, economic and religious dominance—pitting Christian popes, emperors and kings against Muslim caliphs and sultans.
