The name Kurtis has its origins in the Germanic languages, derived from the word "kurti" which means "courteous" or "polite." It gained popularity during the Middle Ages in various regions of Europe, particularly in Germany, France, and the Low Countries.

One of the earliest recorded instances of the name Kurtis can be found in the Carolingian dynasty of the 8th century, where it was used as a first name by several members of the ruling family. Kurtis the Bold, a nobleman who lived around 820 AD, is one of the notable figures from this period to bear the name.

During the High Middle Ages, the name Kurtis was widely used among the nobility and aristocracy across Europe. It was particularly popular in the Holy Roman Empire, where it was associated with chivalry and courtly manners. Kurtis von Leiningen, a 12th-century German nobleman and crusader, is a well-known historical figure who carried this name.

As the name spread across Europe, it took on various spellings and forms, such as Curtis, Curtius, and Curteys. In England, the name Curtis gained popularity during the Norman Conquest, and it is believed to have been introduced by Norman nobles who accompanied William the Conqueror in 1066.

One of the most famous bearers of the name Kurtis in history was Curtius Rufus, a Roman historian who lived in the 1st century AD. His work, "Historiae Alexandri Magni," chronicled the life and campaigns of Alexander the Great and is considered a valuable primary source for studying that period.

Another notable figure was Kurtis of Saxony, a 10th-century German nobleman and military leader who played a significant role in the expansion of the Holy Roman Empire. He was also known for his efforts in promoting Christianity in the region.

In the field of literature, Kurtis Siodmak, a German-American novelist and screenwriter (1902-2000), is remembered for his contributions to the film noir genre, having written screenplays for classics such as "The Killers" and "Criss Cross."

Kurtis Masterson, an American actor and singer (1927-1999), is also a noteworthy bearer of the name. He had a successful career in Hollywood, appearing in numerous films and television shows, and was known for his distinctive baritone voice.
