Emilien is of Latin origin, meaning 'rival' or 'emulous'. It is a variant form of the Latin name Aemilius, which was originally a Roman family name thought to derive from the Latin word 'aemulus', meaning 'rival' or 'emulous'. The name Emilien was quite common in France during the Middle Ages, often used as a given name and also appearing frequently among nobles and saints. Over time, it has been adopted by other languages and cultures, though its usage remains more prevalent in French-speaking countries.
