New Investigation Argues the Crusades Did Not End at Acre, But in a French Courtroom Twenty-Three Years Later
The Crusades did not end at Acre in 1291. They ended in 1314, when Philip IV of France, unable to repay his debt to the Knights Templar, had the Order tried on fabricated charges and its last Grand Master burned. This fully sourced investigation traces the trial, the torture, and the collapse of medieval Europe's most powerful financial network.
- (1888PressRelease) July 19, 2026 - Histories and Castles publishes The Last Crusade: The Trial and Fall of the Knights Templar, a fully sourced digital investigation into the destruction of medieval Europe's most powerful financial institution.
Histories and Castles, the independent medieval history publisher covering England and Wales, has released a new investigative guide: The Last Crusade: The Trial and Fall of the Knights Templar. The guide is available now as an instant PDF download at historiesandcastles.com, priced at £4.99.
Most accounts of the Crusades close with the fall of Acre in 1291, when the Mamluk army ended two centuries of Latin Christian rule in the Holy Land. This guide argues that date marks the wrong ending. What collapsed at Acre was territory. What sustained the crusading project, its banking network, its papal authority, its legal machinery, survived for another twenty-three years, until Philip IV of France, a king who owed the Knights Templar a debt he could not repay, found a legal mechanism to erase it.
The guide traces that argument across five acts, from the fall of Acre through the dawn arrest of every Templar in France on Friday 13 October 1307, the fabricated heresy charges that followed, the Council of Vienne, and the burning of Jacques de Molay, the last Grand Master, in Paris in March 1314. It examines why 105 of 138 Templars questioned in Paris confessed under torture while those questioned outside French jurisdiction, in England, Portugal, and Cyprus, largely did not, and what the destruction of the Order actually dismantled: a banking network that had financed sovereign lending across Europe, and a precedent for how a debtor with the power of the state can destroy a creditor.
The guide is built from primary sources, including trial transcripts and surviving papal bulls such as Vox in excelso and Ad providam, alongside standard modern scholarship including Malcolm Barber's The Trial of the Templars and Joseph Strayer's The Reign of Philip the Fair. A full bibliography is included so that every claim can be checked rather than taken on trust.
The Last Crusade is written by Simon A. Williams, published historian and Editor-in-Chief of Histories and Castles. His previous published titles include The Truth Behind Welsh Myths and Legends, The Pendle Witch Conspiracy, and No Law for the Poor: Justice and Power in Medieval England and Wales. His work examines the hidden forces behind medieval Britain, its law, myth, fear, and power, told through the lives of ordinary people rather than royal narrative.
The guide runs to 24 pages, with an estimated reading time of 60 to 90 minutes, and is formatted for reading on any device or for printing. It is aimed at A-level and undergraduate students seeking an argued account alongside primary source material, as well as general readers who want the evidence behind the claim rather than the claim on its own.
The Last Crusade is the third guide in the Histories and Castles investigative series on the Crusades, following The Holy Land Industry and The Crusade Machine. Two further guides in the series, The Broken Kingdom and The Enemy They Made, are in production.
