The given name Amauri has its origins in the Old Germanic languages, deriving from the words "amal" meaning "work" and "ric" meaning "power" or "rule." It essentially translates to "industrious ruler" or "hardworking leader." The name first emerged during the Migration Period in Europe, between the 4th and 8th centuries AD, when various Germanic tribes were on the move across the continent.

One of the earliest recorded uses of the name Amauri can be found in the Frankish Kingdom, where it was borne by Amauri I, Count of Montfort-l'Amaury, who lived from around 1050 to 1089 AD. He was a prominent figure in the Île-de-France region and played a role in the Norman conquest of England in 1066.

In the 12th century, Amauri de Montfort, also known as Amalric of Montfort, was a French crusader and military leader who participated in the Albigensian Crusade against the Cathars in southern France. He lived from around 1195 to 1241 AD and was known for his brutality in suppressing the Cathar heresy.

Another notable figure with the name Amauri was Amauri de Bène, a French theologian and philosopher who lived from around 1195 to 1206 AD. He taught at the University of Paris and was condemned for his teachings on the eternity of the world and the unity of all intellects.

In the 13th century, Amauri I, Count of Jaffa and Ascalon, was a French nobleman and one of the leaders of the Sixth Crusade. He lived from around 1195 to 1258 AD and played a significant role in the crusader states in the Holy Land.

Another notable figure was Amauri II de Montfort, who lived from around 1240 to 1305 AD. He was a French nobleman and the Count of Narbonne, known for his role in the Aragonese Crusade against the Crown of Aragon in the late 13th century.

While the name Amauri has its roots in the Germanic languages, it has also been adopted and used in various other cultures and regions, particularly in France and other parts of Europe, throughout history.
