Thracian warfare In the 4th century BC, both infantry and cavalry troops started wearing helmets (some of leather) and some peltasts are seen with greaves. Principal weapons in the 4th century BC (as well as earlier) were the spear and short knife. Armor, when it was available (for the nobility), was at first leather or bronze but iron armour started appearing in the 4th century BC. Thracian cavalry would wear leather armor or no armor and would be armed with javelins, a bow, or a spear. Only royal cavalry would wear armor. Oval shields and peltes (even by heavy cavalry) were later
Thracian warfare (plus the onset of winter) meant that this army only held together for about six weeks and any Thracian conquests were ephemeral. The Sapaeans ruled Thrace after the Odrysians until its incorporation to the Roman Empire as a province. Thrace became a Client state of Rome at 11 BC and was annexed at 46 AD. Thrace had the potential to muster a huge number of troops though this rarely occurred. By tradition, Thracians honored warriors and, according to Herodotus, despised all other occupations. The Thracians fought as peltasts using javelins and crescent or round wicker shields called "peltes". Missile weapons
