On a February afternoon in 1908, King Carlos I of Portugal and Crown Prince Luís Filipe crossed Lisbon's great ceremonial square in an open carriage before a watching crowd. Within moments, rifle shots shattered the procession. The king was dead, the heir mortally wounded, and Europe's oldest monarchy suddenly exposed as fragile, vulnerable, and politically doomed.

In The Royal Bloodbath, Jasper Wilson reconstructs the Lisbon regicide with cinematic detail and deep historical investigation. Far beyond the story of an assassination, this book reveals a monarchy already weakened by corruption, political paralysis, authoritarian rule, conspiracy networks, and collapsing public trust. Through secret societies, failed security, urban unrest, and the tense atmosphere of pre-revolutionary Lisbon, the book shows how the killings became the violent climax of a system already breaking apart.

Blending narrative history with political analysis, Wilson follows the road from royal crisis to revolution, exploring not only the assassins and the bloodshed in the square, but also the unfinished investigations, missing files, rumors of foreknowledge, and the rapid decline of the Braganza dynasty afterward. The result is both a gripping historical thriller and a powerful study of how regimes lose legitimacy before they finally collapse.

Atmospheric, dramatic, and rigorously grounded in historical research, The Royal Bloodbath is essential reading for anyone fascinated by royal assassinations, European political history, revolutionary movements, and the violent end of monarchies.
