In the 13th century, the name Amadeo can be found in historical records from the city of Florence. One notable example is Amadeo Cavalcanti, a Florentine philosopher and poet born around 1255 who was a friend and contemporary of Dante Alighieri.

The Amadeo family was also prominent in the Republic of Genoa during the Middle Ages. In the 14th century, Amadeo Doria was a Genoese admiral and statesman who played a significant role in the wars between Genoa and Venice.

As the name spread throughout Italy, variations in spelling emerged, such as Amadei, Amadio, and Amaducci. In the 16th century, the painter Giovanni Amadeo, born around 1447 in Pavía, was known for his work in Milan and other cities in northern Italy.

The surname Amadeo also has a connection to the Savoy dynasty, which ruled over parts of modern-day Italy, France, and Switzerland.
