Phillipe de Plessis
- This article deals with the 12<sup>th</sup> century Knight Templar. For the 16<sup>th</sup> century Huguenot, see Philippe de Mornay.
(1165–1209) was the 13th Grand Master of the Knights Templar
. He was born in the fortress of Plessis-Macé, Anjou
. In 1189 he joined the Third Crusade
as a simple knight, and discovered the Order of the Temple
. After the death of Gilbert Horal
he became Grand Master. He helped uphold the treaty between Saladin
and Richard I
. In the renewal of this treaty in 1208 he suggested that the Teutonic Order
should make a new peace treaty offer with Malek-Adel
. The accord was criticised by Pope Innocent III
There were few military actions during his rule; the Fourth Crusade
never arrived in the Holy Land. The German King was in opposition to the Knights regarding the Gastein
stronghold. The Templars were initially expelled from Germany, but the pope intervened in the dispute.
Relations with the Hospitaliers were tense. During his rule the Order of the Temple reached its greatest height in Europe
His name is last documented in 1209. The Obituary of Reims
gives the date of his death as November 12, 1209.
