The Oath of the
Medieval Teutonic Knights
The oath of the Medieval Teutonic Knights was as follows:
"I... do profess
and promise chastity, giving up all property, and obedience
to God and the Blessed Virgin Mary and to you, Brother ...
Master of the Teutonic Order, and to your successors,
according to the Rules and Regulations of the Order. And I
will be obedient to you, and to your successors, even unto
Teutonic Knights side with Hospitallers and barons in Acre against the
Templars in 1209 which becomes the origin of long-standing opposition
between the Templars and Teutonic Knights. In 1217 Frederick II granted
the Teutonic Knights the same status as the Templars and Hospitallers in
the Kingdom of Sicily. In 1220 Pope Honorius III gave privileges to the
Teutonic Knights; as an order, they now were on the same level as the
Templars and the Hospitallers. In 1226 the "Golden Bull of Rimini" from
Frederick II for the Teutonic Knights giving them wide-ranging authority
in the name of the empire in Prussia. In 1319 the Teutonic Knights'
headquarters moved from Venice to Prussia. In 1410 Lithuanian-Polish
forces defeated the Teutonic Knights at the Battle of Tannenberg,
Prussia, halting the Teutonic Knights’ eastward expansion along the
Baltic and hastening their decline.
