Who were Ninjas?

Answer 1

A ninja or shinobi (忍者 or 忍び) was a Covert_agentor Mercenaryof Feudal_Japanspecializing in unorthodox arts of war. The functions of the ninja included Espionage, Sabotage, Infiltration_tactics, and Assassination, as well as open combat in certain situations. The ninja, using covert methods of waging war, were contrasted with the Samurai, who had strict rules about honor and combat.The origin of the ninja is obscure and difficult to determine, but can be surmised to be around the 14th century. However, the antecedents to the Ninja may have existed as early as the Heian_Periodand early Kamakura_perioderas. Few written records exist to detail the activities of the ninja. The word shinobi did not exist to describe a ninja-like agent until the 15th century, and it is unlikely that spies and mercenaries prior to this time were seen as a specialized group.
