Seimeni (plural of Seimen) designates the group of flintlock-armed infantry mercenaries charged with guarding the hospodar (ruler) and his court in 17th and 18th century Wallachia and Moldavia. They were mostly of Serb and other Balkan origin. The term is of Turkish origin: seğmen means "young armed man". In modern transcriptions of Slavonic, it may also appear as simén (plural: siméni) or siimén (siiméni).
