Long ago, a group called Wu lived in China. 

Long ago, a state called Wu ruled in eastern China. 
Sun Ce was an early leader of the Sun clan. He won many lands. After he died, his brother Sun Quan took over. 
Life in Wu was busy. The people used rivers to move things. They built canals to help trade. 
Later, the state faced many hard times. There were fights among the leaders. A ruler named Sun Hao was not a kind leader. In the end, a new group called the Jin dynasty took over. This ended the time of the Three Kingdoms.
Eastern Wu was a powerful state in ancient China. It was one of three main lands fighting for control. This time is called the Three Kingdoms period. 

The Sun family started the rise of this state. Sun Ce was a leader who won many lands. He fought many battles between the years 194 and 199. After Sun Ce died in the year 200, his brother Sun Quan took over. Sun Quan was a very strong and important leader. In 208, he joined forces with a leader named Liu Bei. They worked together to win the Battle of Red Cliffs.
Sun Quan ruled for more than 30 years. He made Wu an empire in May of 229 AD. His long rule brought stability to southern China. 

Daily life in Wu involved a lot of trade and building. The people used rivers to move goods very easily. They finished building canals like the Jiangnan and Zhedong canals. This helped the economy grow much larger.
Eventually, the state of Wu faced many hard problems. Some later rulers were not kind to their people. There were also many fights within the royal family. In 279, forces from the Jin dynasty attacked Wu from six sides.
Eastern Wu, also known as Sun Wu, was a major dynastic state in ancient China. It was one of three powerful states competing for control during the Three Kingdoms period. The name Wu comes from the Jiangnan region, which is the Yangtze River Delta. Historians call it Eastern Wu to distinguish it from older states with similar names. They also call it Sun Wu because the ruling family name was Sun. 
The rise of the state began with the Sun clan's military successes. Sun Ce, the son of the warlord Sun Jian, led conquests in the Jiangdong and Wu regions between 194 and 199. He seized territories from various warlords like Liu Yao and Yan Baihu. After Sun Ce was assassinated in 200, his brother Sun Quan took leadership. Sun Quan maintained autonomous rule while paying nominal allegiance to the Han dynasty. 
Sun Quan's leadership was defined by strategic alliances and conflicts. In 208, he allied with the warlord Liu Bei to defeat Cao Cao at the Battle of Red Cliffs. This victory secured the Sun family's position in the south. However, the alliance later broke in 219 over the Jing Province territory. Sun Quan's general, Lü Meng, invaded the province and captured the defender Guan Yu. This conflict led to the Battle of Xiaoting, where Sun Quan's general Lu Xun defeated Liu Bei.
After these battles, Sun Quan's domain grew to include the southern part of Jing Province. This area covered much of modern Hunan and parts of Hubei. In 222, Sun Quan declared complete independence from the state of Cao Wei. By May 229, he officially declared himself emperor. His long reign of over 30 years brought stability to southern China. 
During his rule, Wu faced constant military pressure from the north. Wu fought several major wars against the state of Wei at Ruxu, Shiting, and Hefei. Despite these conflicts, the borders remained relatively stable. Wei never conquered the lands south of the Yangtze River. Similarly, Wu never gained territory north of the river. 
The economy of Eastern Wu flourished through trade and infrastructure. The construction of the Jiangnan and Zhedong canals improved river transportation. This helped the movement of goods and people across the region. Wu imported cotton from the state of Shu Han. The state also saw growth in the shipbuilding, salt, and metal industries.
Wu was also part of a vast international trade network. The state engaged in overseas trade with countries like Vietnam and Cambodia. They also traded with distant regions such as India and the Middle East. This economic activity supported a diverse culture. The language, known as Old Jiangdong, eventually evolved into the modern Wu languages.
Internal struggles eventually weakened the state. A succession dispute between Sun Quan's sons, Sun He and Sun Ba, caused deep divisions in the court. Later, the ruler Sun Hao became a tyrant. His cruelty and interest in luxury caused widespread anger. In 279, the Jin dynasty launched a massive attack from six directions. The Wu forces suffered many defeats, including the death of Chancellor Zhang Ti. Sun Hao surrendered on May 31, 280. This surrender ended the Three Kingdoms period and the state of Wu.
