Enter Toyotomi Hideyoshi, a guy whose leadership abilities and authoritative power propelled him to the position of one of Nobunaga's three right-hand men. Following the assassination of Nobunaga and his eldest son in 1582, Hideyoshi avenged their murders at the Battle of Yamazaki and made peace with a rival clan. He then went on to defeat another rival clan at the Battle of Nagashino later that year. In 1585, Hideyoshi invaded Kyūshū and defeated another enemy army at the Battle of Kiyosu. That same year, he also defeated an army of Tōngguō (the former Chinese allies of Japan) at the Battle of Miyako.
In addition to being a brave warrior, Hideyoshi was also known for being extremely loyal to those who had helped him achieve greatness. After defeating all of his rivals, he decided to devote himself to teaching swordsmanship. He created many new techniques and taught them only to elite warriors who could pay him well.
Hideyoshi died in 1598 at the age of 54. But even after his death, his influence continued to grow among the people.
In 1615, over 100 years after Hideyoshi's death, his grandson Tokugawa Ieyasu became the first shogun of the Tokugawa dynasty. The dynasty would go on to rule Japan for nearly 200 more years.
Nobunaga's death Seeking revenge for his master's death, Hideyoshi made peace with the Mori clan and, thirteen days later, faced and killed Mitsuhide in the Battle of Yamazaki, avenging his lord (Nobunaga) and assuming Nobunaga's authority and power for himself.
Mitsuhide was a retainer of Nobunaga who attempted to assassinate him but failed. After the failure of his attempt, he fled to Sakhalin where he lived as a monk until he was summoned by Hideyoshi to fight against their common enemy.
Hideyoshi outmaneuvered and defeated Mitsuhide in battle and took his head as proof of victory. Hideyoshi then sent his army back home but kept Mitsuhide's son Harumasa under his protection so that he could use him as a hostage should anything happen to Hideyoshi. In exchange, Harumasa would marry one of Hideyoshi's daughters.
After this victory, Hideyoshi ordered his generals to cease hostilities with the Mori clan and make peace with them. He then returned home to prepare for another war against Oda Nobunaga's grandson Tokugawa Ieyasu. The Battle of Sekigahara was to be the final battle of the Sengoku Jidai period.
Hideyoshi was able to establish himself as the ruler of most of Japan by skillfully combining military operations with diplomacy among his rival daimyo. Hideyoshi assassinated Mitsuhide first, then maneuvered to obtain the backing of Nobunaga's relatives and other powerful daimyo, or feudal lords. In 1582, he defeated Nobunaga at the Battle of Nagashino and ended his career as a force to be reckoned with.
In addition to being a successful general, Hideyoshi was also very good at politics. He knew that to achieve stability in Japan, he had to avoid civil wars and keep his rivals from forming an alliance against him. So instead of fighting each other, he used his political skills to bring about peace between them. This allowed him to dominate the scene until his death in 1598.
Japan was still recovering from the devastation of war when Hideyoshi came into power. The country was divided into many small fiefdoms called "daimyo," who ruled their territories independently of one another. Most daimyo were loyal to one leader only out of fear of losing their powers if they refused; some even married into another clan so as to avoid conflict. This state of affairs made it difficult for anyone to become strong enough to rule over all of Japan.
Hideyoshi decided to change this by using his army to defeat his rivals one by one.
After leading victorious wars in his lord's honor, Hideyoshi was able to avenge Nobunaga's death and rapidly rose to the top of the samurai order. By 1590, he had finished the mission of uniting Japan via military and political methods, establishing his headquarters in Osaka. He died the next year at the age of 56.
Ieyasu was one of the most important generals in Japanese history. His mastery of strategy and tactics helped him defeat all rivals, including Hideyoshi, who died after making Ieyasu the leader of the country. Ieyasu is also famous for having established a government system based on trust, which prevented any conflict between the clans after Nobunaga's death. This trust was evident in everything from diplomacy to warfare--Ieyasu would sometimes send letters to enemies warning them not to attack his territory, while at other times he would go to war with them without first asking permission.
Trust is an important factor in maintaining harmony within any society. It allows different groups to work together toward a common goal without fear of betrayal or violence, which would break down if people were afraid others will harm them if they do not cooperate.
In conclusion, Nobunaga Hideyoshi and Ieyasu helped unify Japan by building trust among the leaders of different provinces. They did this by defeating their rivals in battles and honoring agreements they made with each other during peace talks.
He was Toyotomi Hideyoshi's nephew and servant from 1590 until 1598, when he was Japan's unifier and king. Hidetsugu, despite being Hideyoshi's closest adult male relative, was accused of crimes and plotting a coup following the birth of Hideyoshi's son, and he was ordered to commit himself. Hidetsugu refused, and so he was killed.
In reality, Hidetsugu had been loyal to his uncle until the end. After Hideyoshi's death in 1598, Hidetsugu tried to continue on as head of the family with help from Tokugawa Ieyasu, one of Hideyoshi's allies. However, his efforts were not successful, and so he went into exile in the Kingdom of Spain.
During his time in Europe, Hidetsugu met with other members of the Tokugawa clan who had been exiled by Ieyasu after the Battle of Sekigahara. Together, they planned to return to Japan and overthrow Ieyasu, but Hidetsugu died before their plan could come to fruition. Following his death, his wife Chikako continued to work with Ieyasu's son Tokugawa Hidetada to restore peace to Japan.
In conclusion, Hideyoshi killed Hidetsugu because he feared that Hidetsugu would try to take over his empire following his death.
Mitsuhide He and other Oda generals, including Tokugawa Ieyasu, rushed to revenge the murder of their master. Hideyoshi was the first to catch up with Mitsuhide, defeating and killing him in the Battle of Yamazaki only 13 days after Nobunaga's death.
Ieyasu then took over the leadership of the alliance and continued the war against Nobunaga's descendants. In 1598 he defeated and killed an old and sick Nobunaga at the Battle of Sekigahara, ending the First War between the Takeda and the Ishido clans.
Nobunaga's death had several consequences for Japan. First, it forced the leaders of the remaining armies to seek a diplomatic solution to the conflict. Second, it left his son Hidetada as the leader of one faction and Ieyasu's son Tokugawa Hidetada as the leader of another faction. The final outcome of the war would determine which clan would rule over all of Japan.
In addition to these political factors, there was also a social factor contributing to the decline of the Takeda dynasty: they were just not that popular with their subjects. The Takeda ruled over a small part of western Japan and they imposed their authority on everyone else by force. The people living under their dominion were not really happy with this situation and they complained about the harsh practices of the Takeda rulers.
