Long ago, Japan was very quiet. 

Long ago, Japan stayed away from other lands. 


For a long time, Japan stayed away from other lands. This changed in the mid-1850s. 

Many people in Japan disagreed on what to do. Some groups wanted to keep the old ways. They wanted to push foreigners away. Other groups wanted to learn new things. They studied Western science and weapons. 
The Bakumatsu was a time of huge change in Japan. It took place during the final years of the Edo period. During this time, Japan ended its policy of staying isolated from the world. 
Many different groups fought for control during these years. Some groups were pro-imperial nationalists who wanted to support the Emperor. Others were shogunate forces that included elite swordsmen. Many smaller groups also tried to use the chaos to gain power. There were two main reasons for the unrest in the land. First, some local lords felt they were being treated unfairly. These lords had been left out of power since the year 1600. Second, many people felt angry about the arrival of Westerners. They used the phrase "revere the Emperor, expel the barbarians" to show this feeling.
Foreign ships began visiting Japan more often in the 1800s. They were looking for supplies or places to help with shipwrecks. In 1808, a British ship called the HMS Phaeton caused a shock in Nagasaki. This led the government to guard its ports even more tightly. In 1825, the shogunate even made a rule to stop all contact with foreigners. 
Everything changed in July 1853 when Commodore Matthew Perry arrived. He brought a fleet of four ships to Edo Bay. 


These new treaties changed how Japan worked with the world. In 1858, Townsend Harris helped negotiate a new trade treaty. 
The Bakumatsu refers to the final years of the Edo period in Japan. This era saw the end of the Tokugawa shogunate. It was a time of massive transition for the nation. Japan moved from a feudal system to a modern empire under the Meiji government. This change happened between 1853 and 1867. The primary cause was pressure from foreign military and diplomatic forces. This pressure forced Japan to end its isolationist policy, known as sakoku. 
Political tension divided the country into two main ideological camps. One group consisted of pro-imperial nationalists. These people wanted to restore power to the Emperor. The other group supported the shogunate forces. This group included many elite swordsmen. Many smaller factions also tried to use the chaos to seize power. Two main forces drove this dissent. First, many daimyo, or outside lords, felt resentment. Their ancestors had lost the Battle of Sekigahara in 1600. Because of that defeat, they were excluded from powerful positions. Second, many people felt strong anti-Western sentiment. They used the slogan "revere the Emperor, expel the barbarians" to express this anger.
Before the major arrival of American ships, Japan faced growing friction with foreign vessels. Western ships were increasing their presence near Japan for whaling and trade with China. They often looked for supply bases or help with shipwrecks. In 1808, the Royal Navy frigate HMS Phaeton demanded supplies in Nagasaki Harbour. This event shocked the Tokugawa government. They responded by guarding their ports even more tightly. In 1825, the shogunate issued an order prohibiting all contact with foreigners. This strict rule remained in place until 1842.
Despite these rules, some Japanese people began studying Western sciences. This field was called "Western studies." Some leaders wanted to use foreign technology to protect Japan. Takashima Shūhan obtained weapons like mortars and firearms through the Dutch at Dejima. Various domains, such as Satsuma, Saga, and Chōshū, sent students to learn from him. These southern domains were often the first to face Western intrusions. By 1852, the Satsuma and Saga domains had built reverberatory furnaces. These furnaces produced the iron needed to make firearms. 
A major turning point occurred in July 1853. Commodore Matthew Perry arrived in Edo Bay with a four-ship squadron. 

Abe eventually signed the Treaty of Kanagawa in March 1854. This treaty opened the ports of Shimoda and Hakodate to American whaling ships. It also guaranteed safety for shipwrecked American sailors. Following this, other nations arrived to seek their own treaties. The Russian Empire sent Vice Admiral Euphimy Putiatin to negotiate. 
In 1858, Townsend Harris negotiated the Treaty of Amity and Commerce. 
The Bakumatsu period was also marked by natural disasters. Between 1854 and 1855, Japan experienced the Ansei great earthquakes. There were 120 major and minor tremors recorded. This included an 8.4 magnitude earthquake in 1854. A tsunami from this quake even sank the Russian ship Diana. These disasters were sometimes seen as signs of divine displeasure. Ultimately, the chaos of the Bakumatsu led to the Boshin War. The defeat of the pro-shogunate forces at the Battle of Toba–Fushimi marked the end of the old way. This paved the way for the modern Meiji era.
