Adrian has Roman roots that stretch back to the ancient town of Hadria, located in what is now northern Italy. The name developed from the Roman family name Hadrianus and became a given name that spread across the Roman Empire. The most famous bearer was the Emperor Hadrian, who ruled from 117 to 138 AD and is best known for building Hadrian's Wall across northern Britain. The name remained in use through the Middle Ages and was adopted by several popes, including Pope Adrian IV, the only English pope. In modern times, Adrian has been a familiar and well-used name in Europe and the Americas. It has a refined, slightly sophisticated sound that works well in many languages. In the United States, Adrian has been a consistently popular choice for boys, and it has also gained popularity for girls in some countries, though it remains predominantly male.
