SōheiSōhei were Buddhist warrior monks of both classical and feudal Japan. At certain points in history, they held considerable power, obliging the imperial and military governments to collaborate. The prominence of the sōhei rose in parallel with the ascendancy of the Tendai school's influence between the 10th and 17th centuries. The warriors protected land and intimidated rival schools of Buddhism, becoming a significant factor in the spread of Buddhism and the development of different schools during the Kamakura period.
Ikkō-shūor "single-minded school" is usually viewed as a small, militant offshoot from Jōdo Shinshū Buddhism though the name has a complex history. Originally Ikkō-shū was an "obscure band of Pure Land proponents" founded by Ikkō Shunjō in the fifteenth century. He was a disciple of Ryōchū of the Chinzei branch of Jōdo-shū Buddhism) and similar to Ippen's Ji-shū. However, when the religious and military-political establishment began to crack down on the Nembutsu, little distinction was made between the various factions.
Sengoku periodThe Sengoku period is the period in Japanese history in which civil wars and social upheavals took place almost continuously in the 15th and 16th centuries. Though the Ōnin War (1467) is generally chosen as the Sengoku period's start date, there are many competing historiographies for its end date, ranging from 1568, the date of Oda Nobunaga's march on Kyoto, to the suppression of the Shimabara Rebellion in 1638, deep into what is traditionally considered the Edo period.
Oda NobunagaOda Nobunaga was a Japanese daimyō and one of the leading figures of the Sengoku period. He is regarded as the first Tenka-bito of Japan. Nobunaga was an influential figure in Japanese history and is regarded as one of the three great unifiers of Japan, along with his retainers Toyotomi Hideyoshi and Tokugawa Ieyasu. Hideyoshi later united Japan in 1591 and invaded Korea a year later. However, he died in 1598, and Ieyasu took power after the Battle of Sekigahara in 1600, becoming shogun in 1603, and ending the Sengoku period.
Toyotomi HideyoshiToyotomi Hideyoshi, otherwise known as Kinoshita Tōkichirō and Hashiba Hideyoshi, was a Japanese samurai and daimyō (feudal lord) of the late Sengoku period regarded as the second "Great Unifier" of Japan. Hideyoshi rose from a peasant background as a retainer of the prominent lord Oda Nobunaga to become one of the most powerful men in Japan. Hideyoshi succeeded Nobunaga after the Honnō-ji Incident in 1582 and continued Nobunaga's campaign to unite Japan that led to the closing of the Sengoku period.
Buddhism in JapanBuddhism has been practiced in Japan since about the 6th century CE. Japanese Buddhism (Nihon no Bukkyō) created many new Buddhist schools, and some schools are original to Japan and some are derived from Chinese Buddhist schools. Japanese Buddhism has had a major influence on Japanese society and culture and remains an influential aspect to this day. According to the Japanese Government's Agency for Cultural Affairs estimate, , with about 84 million or about 67% of the Japanese population, Buddhism was the religion in Japan with the most adherents, followed by Shinto, though a large number of people practice elements of both.
DaimyoDaimyo were powerful Japanese magnates, feudal lords who, from the 10th century to the early Meiji period in the middle 19th century, ruled most of Japan from their vast, hereditary land holdings. They were subordinate to the shogun and nominally to the emperor and the kuge. In the term, dai means 'large', and myō stands for 名田, meaning 'private land'. From the shugo of the Muromachi period through the Sengoku to the daimyo of the Edo period, the rank had a long and varied history.
Tokugawa IeyasuTokugawa Ieyasu was the founder and first shōgun of the Tokugawa Shogunate of Japan, which ruled from 1603 until the Meiji Restoration in 1868. He was one of the three "Great Unifiers" of Japan, along with his former lord Oda Nobunaga and fellow Oda subordinate Toyotomi Hideyoshi. The son of a minor daimyo, Ieyasu once lived as a hostage under daimyo Imagawa Yoshimoto on behalf of his father. He later succeeded as daimyo after his father's death, serving as a vassal and general of the Oda clan, and building up his strength under Oda Nobunaga.
Ashikaga shogunateThe Ashikaga shogunate, also known as the Muromachi shogunate, was the feudal military government of Japan during the Muromachi period from 1336 to 1573. The Ashikaga shogunate was established when Ashikaga Takauji was appointed Shōgun after overthrowing the Kenmu Restoration shortly after having overthrown the Kamakura shogunate in support of Emperor Go-Daigo. The Ashikaga clan governed Japan from the Imperial capital of Heian-kyō (Kyoto) as de facto military dictators along with the daimyō lords of the samurai class.
