Final answer:
The Mongols' nomadic hardiness, unique battlefield tactics, and organized cavalry army, under Genghis Khan's rule, made them well-suited for conquest.
Step-by-step explanation:
Several characteristics of the Mongols under the leadership of Genghis Khan made them exceptionally suited to a career of conquest. First, their expertise as nomads on the steppes gave them attributes like hardiness and mobility, essential for successful military campaigns. Secondly, their formidable battlefield tactics, including sneak attacks, feigned retreats, and psychological warfare, enabled them to overcome opponents efficiently. Additionally, their societal structure gave them a distinct advantage in attracting warriors, as conquests meant the opportunity to gain loot and status.
The Mongols' highly disciplined and organized cavalry army, able to execute complex maneuvers and famed for their archery while on horseback, was critical to their success. Their army was not only highly mobile but also adaptable to various environments beyond the steppe, which made their expansion possible. Finally, the promise of wealth and the spoils of war encouraged the participation of Mongol warriors in these conquests, further contributing to their expansive reach and influence.
