Adian is of Latin origin, derived from the Roman family name Aemilius, which was often shortened to Adeus. It means 'rival' or 'equal'. Adian was brought into prominence during the Middle Ages in Europe, though it remains relatively uncommon today. In some cases, it may also be a variant spelling of Adrian, which is more widely recognized and shares similar roots.
"The name Adian experienced a significant surge in popularity between the years 2000 and 2006, with a notable peak of 89 births in 2006. However, since then, the number of annual births has steadily declined, reaching an all-time low of 14 births in 2023."
