Eurasian nomads
Trousers enter recorded history in the 6th century BC, on the rock carvings and artworks of Persepolis, and with the appearance of horse-riding Eurasian nomads in Greek ethnography. At this time, Iranian peoples such as Scythians, Sarmatians, Sogdians and Bactrians among others, along with Armenians and Eastern and Central Asian peoples such as the Xiongnu/Hunnu, are known to have worn trousers. Trousers are believed to have been worn by both sexes among these early users.
