The English hospitaller Order of St. Thomas of Acre was originally founded as a purely religious Order in Acre in 1190, by King Richard the Lionheart, during the Third Crusade. It was devoted to Saint Thomas Becket and retained an English character throughout its history.


In 1228, the Bishop of Winchester reorganized the Order into a Military Monastic Order on the model of the Teutonic Order. The habit was a white mantle bearing a red cross with a scallop shell. The Order did not play a major military role, and after the fall of Acre in 1291 it retired to Cyprus. The Order also acquired lands in Sicily, southern Italy and Greece.


Sometime in the 1370s the Order moved its headquarters to its London house at the site of what is now Mercers hall a house which was the birthplace of Thomas Becket. There it survived as a mainly Hospital Order until it was dissolved along with other orders in 1540.


It was revived in the early 18th century in Jacobite circles, and was one of several organizations active in promoting the Jacobite cause. It seems to have been under the protection of the exiled Stuarts in France. This revived Order existed until the early 1900’s.


The current Order claims no direct links with the original Crusader Order or any revival.


In May 2021, the Rt. Hon. Earl of Loudoun, co-lateral descendant of King Richard the Lionheart, was appointed as Protector of the Order.
