The word samurai originated in the tenth century, although its most widespread use is relatively modern

(Edo period), particularly around the year 1615 when Tokugawa Ieyasu finally debuted in the "winter campaign" Hideyori's revolt and his 10,000 ronins at Osaka Castle.

 

The full meaning of the word samurai can be defined from this point on and considering the historical context in which it will be much like an armed officer at the level of a law enforcement officer.

 

The term and figure of the bushi appear concretely in the eighth century, but it will not be until the twelfth century, 1185, just when they come to power. The most notable differences with samurai, previously named, are mainly in the bushi was a warrior more identified with the battlefield, which obviously was not involved in the official bureaucratic state of work, carrying his armor, his life was intimately bound to war, and fought with courage and tenacity for the glory of her clan and her own, for which they did not hesitate to mourn the least occasion to appear.
