In the late Heian period, the Japanese emperor gradually became a figment without real power, and real power was held by nominal ministers, who were called "people of the world". Among the leading figures of japan's Sengoku period, several shoguns of the Muromachi shogunate, as well as Hosokawa Masamoto, Miyoshi Nagayoshi, Oda Nobunaga, Toyotomi Hideyoshi, and Tokugawa Ieyasu, were considered to be the "people of the world" in the Sengoku period.
Several shoguns of the Muromachi shogunate were understandably regarded as nominal "people of the world" because they held the title of shogun. Hosokawa Masamoto was a "half-shogun" in charge of the shogunate, and it is understandable to be regarded as a nominal "man of the world". Oda Nobunaga, Toyotomi Hideyoshi, and Tokugawa Ieyasu are uncontroversial "people of the world". So why is Miyoshi Nagayoshi regarded as one of the "ten-man" of Japan's Sengoku period?
The Miyoshi clan, who was born in Miyoshi Nagayoshi, was originally a vassal of the Shogunate governor of the Hosokawa clan, the Shuryū of the Kiyokazu Genji clan. After Hosokawa Masamoto's death, a decades-long civil war broke out among the Hosokawa clan. Miyoshi Nagayoshi's father, Miyoshi Motonaga, supported Hosokawa Harumoto during the Hosokawa Civil War and eventually became the first hero of Hosokawa Haruoto's victory. In return, Hosokawa Haruoto gave much of the power in his family to Miyoshi Motonaga.
However, in the Sengoku period of "Shimokami", hosokawa pipe collar could override Ashikaga shogun, and Miyoshi Shigetoshi could of course also override Hosokawa pipe collar. Miyoshi's power soon aroused the suspicion of Hosokawa Haruoto, who eventually killed Miyoshi at the instigation of Miyoshi Masamune, Kizawa Nagamasa, Kenji Yanagimoto, and others. When Miyoshi Motonaga was killed, his son Miyoshi Nagayoshi was a child who was only ten years old.
Miyoshi Nagayoshi had to return to his hometown of Awa (located on Shikoku Island) to gather strength and wait for the right moment. In the eighth year of astronomy (1539), the seventeen-year-old Miyoshi Nagayoshi once again led his army into by intervening in the Hosokawa Clan Civil War. After years of fighting, Miyoshi Nagayoshi defeated almost all of Kinki's enemies, including Hosokawa Haruoto. In the third year of Yonglu (1560), Miyoshi entered its heyday.
In the heyday of Miyoshi Nagayoshi, Miyoshi controlled Yamashiro, Yamato, Iga, Hanoi, Watazumi, Awa, Sanuki, Settsu Half-Kingdom, and Kii-Half-Kingdom, incorporating the region, japan's richest at the time, and the strength of Japan was the largest. Most importantly, Miyoshi Nagayoshi controlled the Muromachi shogunate and the Hosokawa shogunate, and was able to command Japan in the name of the shogunate.
With the strongest strength and the political status of "holding the general to make the daimyo", Miyoshi Nagayoshi became the biggest figure in Japanese political influence at that time. Because of this, some people in later generations regarded Miyoshi Nagayoshi as one of the "ten-man" of Japan's Sengoku period. However, there are many problems in the hegemony of Miyoshi Changqing, and the decline of the Miyoshi family has already appeared in the later years of Miyoshi Changqing.
