It came to an end when all political power was unified under the Tokugawa shogunate.  - The Warring States period was an era in ancient Chinese history following the Spring and Autumn period and concluding with the Qin wars of conquest that saw the annexation of all other contender states, which ultimately led to the Qin state's victory in 221 BC as the first unified Chinese empire known as the Qin dynasty. Although different scholars point toward different dates ranging from 481 BC to 403 BC as the true beginning of the Warring States, Sima Qian's choice of 475 BC is generally the most often cited and popularly accepted one. The Warring States era also overlaps with the second half of the Eastern Zhou dynasty, though the Chinese sovereign, known as the king of Zhou, ruled merely as a figurehead and served as a backdrop against the machinations of the warring states.  - Shinmen Sokan ( active 16th century ) was a Japanese lord , daimyo of the Shinmen clan (  Shinmen - shi ) during the middle of the Sengoku period .

One such swordsman of note that served under Sokan was the famous Shinmen Munisai , the father of the legendary swordsman Miyamoto Musashi . In 1589 , Sokan ordered Munisai to kill Honiden Gekinosuke ( a minor student under Munisai ) for unknown reasons . Due to this fact however , Munisai was forced to leave his village of Miyamoto .  - , also known as Shinmen Takez, Miyamoto Bennosuke or, by his Buddhist name, Niten Draku, was an expert Japanese swordsman and rnin. Musashi, as he was often simply known, became renowned through stories of his excellent and unique double-bladed swordsmanship and undefeated record in his 60 duels (next to 33 of It Ittsai). He was the founder of the Hyh Niten Ichi-ry or Niten-ry style of swordsmanship and in his final years authored , a book on strategy, tactics, and philosophy that is still studied today.  - , which can be loosely translated as "the school of the strategy of two heavens as one", is a kory (ancient school), transmitting a style of classical Japanese swordsmanship conceived by the warrior Miyamoto Musashi. Hyh Niten Ichi-ry is mainly known for the two-swordkatana and wakizashikenjutsu techniques Musashi called "Niten Ichi" (, "two heavens as one") or "Nit Ichi" (, "two swords as one").  - Originally named It Yagor, he at the age of fourteen found himself in a little seaside village called Izu. Legend tells that he floated across the Sagami Bay on a piece of driftwood from shima Island, part of the Izu Islands. The trust of the local villagers was earned when Yagor chased away a group of bandits that went around raiding and pillaging. As he desired to be a great swordsman, the villagers paid for Yagor's travels in seeking out a master. On his journey, Yagor reached Tsurugaoka Hachimang Shinto shrine in Kamakura where he paid homage to the gods and practiced his swordsmanship. One particular day, an unknown assailant tried to attack Yagor but he somehow unconsciously and without thinking drew his sword and cut him down in one swift stroke. Not understanding this technique, Yagor would later describe it as "Musken" (), a fundamental aspect of his swordsmanship's philosophy. Musken is either an offensive or defensive technique that is delivered spontaneously and without thinking, fully anticipating an opponent's movement; a type of extra-sensory perception similar to mushin.  - A was a samurai with no lord or master during the feudal period (11851868) of Japan.
