How did nomadic people from asian steppes manage to do such devastation to Europe?
The nomadic people of the Asian steppes have a long history of raiding and devastating areas in Europe, particularly the Mongols, Scythians, and the Magyars. All of these peoples manage to cause such widespread devastation for a number of reasons.
Firstly, their largely cavalry based armies were able to easily defeat medieval armies of the time which had no method of defending against their tactics. They were also able to travel extremely long distances in a short amount of time. Some records claim that some Mongol armies were able to travel up to 100 miles in a day, a distance that was impossible for other armies of the time.
The large numbers of people within these nomadic tribes also made it possible for them to overwhelm villages, towns, and cities that were not prepared to face these peoples and their tactics. As a whole, these nomadic tribes took advantage of their speed and battle tactics to quickly outpace and outmaneuver enemy armies and to easily overwhelm large regions of Europe.
