How did the Templars' relations with nobles change their Holy Land property?
Research question: What do the surviving sources say about how the changing relationship between the Templars and the Frankish nobility in the Holy Land affected the Order's landholdings?
The records show that in the 13th century the Templars held four fortresses in the Kingdom of Jerusalem, including Sidon and Beaufort, which were ceded by Julien, lord of Sidon 1. Around 1235, the Templars reportedly received a large monetary payment and recognition of their sovereignty over all their possessions in the Amanus Mountains 3. Their conduct in the 1230s strained relations with the Antiochene prince, and Armand of Périgord agreed to attack the Armenian kingdom with Bohemond V to avenge Templars executed by Hethoum 4. The provided facts do not directly explain how these shifting ties with the Frankish nobility shaped the Order's landholdings over time, and the only later fact concerns the Hospitallers obtaining much Templar property after the suppression 2. The newest dated fact runs from 1312 onward, roughly 714 years before October 2026 2.
