The name Armondo is derived from the German name Armund, which itself comes from the Old German words "hari" meaning army and "mund" meaning protection. It originally referred to a person who was a protector of the army or a military leader. The earliest recorded use of the name dates back to the 8th century in the Frankish kingdom of present-day Germany and France.

Armondo was a relatively common name among the Germanic tribes and later spread to other parts of Europe during the Middle Ages. One of the earliest known bearers of the name was Saint Armondo, a Benedictine monk who lived in the 9th century in the Kingdom of Italy. He is venerated as the patron saint of soldiers and protectors.

In the 11th century, an Armondo was recorded as a knight in the service of William the Conqueror, the Norman king who invaded England in 1066. This Armondo is believed to have been part of the Norman army that fought in the Battle of Hastings.

During the Renaissance period, an Italian artist named Armondo Raimondi (1470-1527) gained fame for his engravings and etchings. He worked in the workshop of Raphael and is considered one of the most influential printmakers of the 16th century.

Another notable bearer of the name was Armondo Diaz (1861-1928), an Italian military leader who served as the Chief of Staff of the Italian army during World War I. He is credited with leading the successful Italian offensive against the Austro-Hungarian forces in the Battle of Vittorio Veneto in 1918, which led to the end of the war on the Italian front.
