5.1 Qin dynasty unification of China

The Qin dynasty's unification of China marked a pivotal moment in ancient Chinese history. This period saw the end of centuries-long political fragmentation and the birth of a centralized empire that would shape China for millennia to come.

Qin Shi Huang, the first emperor, implemented sweeping reforms to consolidate power. These included standardizing writing, currency, and measurements, as well as constructing vast infrastructure projects like the Great Wall. His legacy laid the foundation for imperial China's future.

Warring States period

• The Warring States period (475-221 BCE) was a time of political fragmentation and constant warfare in ancient China following the decline of the Zhou dynasty
• This period saw the rise of seven major states (Qin, Chu, Yan, Han, Zhao, Wei, and Qi) that competed for power and territory through military conquests, alliances, and reforms
• The Warring States period was a formative era in Chinese history that laid the groundwork for the eventual unification under the Qin dynasty

Qin state

• The Qin state, located in the western part of China, was one of the seven major powers during the Warring States period and eventually emerged as the unifier of China
• Qin had several advantages that contributed to its rise, including a strategic location, rich natural resources, and a martial culture that emphasized military discipline and conquest

• Qin Shi Huang's unification brought an end to centuries of political fragmentation and warfare, establishing a centralized empire that would endure for over 2,000 years
• The Qin unification had far-reaching consequences for Chinese society, culture, and politics, setting the stage for the development of a shared Chinese identity and civilization

Centralization of power

• Qin Shi Huang centralized power in the hands of the emperor, abolishing the old feudal system and establishing a bureaucratic government controlled by the imperial court
• The Qin government was divided into a hierarchy of administrative units, with the emperor at the top and a network of officials and bureaucrats responsible for implementing his policies

• Other notable projects included the Epang Palace, a grandiose imperial residence, and the famous Terracotta Army, a collection of life-sized clay soldiers buried with Qin Shi Huang

Qin administrative system

• The Qin dynasty established a highly centralized and hierarchical administrative system that served as a model for future Chinese dynasties
• This system was designed to maintain tight control over the population, enforce imperial policies, and extract resources and labor for the state
• The Qin administrative system represented a significant departure from the decentralized feudalism of the Zhou dynasty and the Warring States period

Abolition of feudalism

• One of the key features of the Qin administrative system was the abolition of the old feudal order, in which power was held by hereditary aristocratic families
• Qin Shi Huang stripped the aristocracy of their lands and titles, replacing them with a centrally appointed bureaucracy loyal to the emperor
• This move eliminated potential rivals to the emperor's power and ensured that all authority emanated from the imperial court

Establishment of commanderies and counties

• The Qin empire was divided into a hierarchical system of administrative units, with commanderies (jun) at the top and counties (xian) at the bottom
• Commanderies were large provinces governed by centrally appointed officials known as commandants (junshou), who were responsible for maintaining order, collecting taxes, and implementing imperial policies
• Counties were smaller units within the commanderies, each governed by a magistrate (ling) appointed by the commandant
• This system allowed the Qin government to maintain tight control over the population and extract resources and labor for state projects

Meritocratic bureaucracy

• The Qin dynasty established a meritocratic bureaucracy in which officials were selected and promoted based on their abilities and performance rather than their family background or social status
• Candidates for official positions were required to pass examinations testing their knowledge of Legalist philosophy, administrative skills, and loyalty to the emperor
• This system helped to create a professional and efficient bureaucracy that was loyal to the state rather than to aristocratic families or regional interests
• However, the Qin bureaucracy was also known for its harshness and inflexibility, with officials often prioritizing the letter of the law over individual circumstances or human needs

Qin legal system

• The Qin dynasty is famous for its strict and harsh legal system, which was based on Legalist philosophy and emphasized the absolute authority of the state over the individual
• The Qin legal code was designed to maintain social order, punish criminals, and deter potential offenders through severe punishments and collective responsibility
• While the Qin legal system was effective in maintaining order and centralizing power, it was also criticized for its brutality and lack of mercy

Legalist philosophy

• The Qin legal system was heavily influenced by Legalist philosophy, which emphasized the importance of strict laws, harsh punishments, and the absolute authority of the ruler
• Legalists believed that human nature was inherently selfish and that people could only be controlled through fear and punishment
• They argued that the state should use law as a tool to shape human behavior and maintain social order, rather than relying on moral education or virtuous leadership
• Key Legalist thinkers included Shang Yang, Han Feizi, and Li Si, who served as advisors to Qin rulers and helped to shape the Qin legal system

Strict laws and punishments

• The Qin legal code was known for its severity and its use of harsh punishments to deter crime and maintain social order
• Punishments included execution, mutilation, forced labor, and exile, often applied not only to the offender but also to their family members and associates
• Minor offenses such as tax evasion or criticism of the government could result in severe penalties, creating a climate of fear and obedience
• The Qin also made extensive use of informers and secret police to monitor the population and report on any signs of dissent or disloyalty

Emphasis on collective responsibility

• A key feature of the Qin legal system was its emphasis on collective responsibility, in which entire families or communities could be punished for the crimes of an individual
• This policy was designed to encourage people to police each other's behavior and report any signs of disloyalty or disobedience to the authorities
• Collective responsibility also served as a way to deter potential offenders by making them fear the consequences not only for themselves but also for their loved ones
• Critics argued that this system was unjust and created a climate of fear and paranoia, but Qin officials believed it was necessary to maintain social order and political stability

Qin military

• The Qin dynasty was known for its powerful and well-organized military, which played a crucial role in the unification of China and the maintenance of Qin rule
• The Qin military was a professional force that relied on conscription, training, and strict discipline to create a formidable fighting machine
• Innovations in weapons, tactics, and organization made the Qin military one of the most advanced and effective of its time

Mass infantry armies

• The core of the Qin military was its mass infantry armies, which were composed of conscripted peasants and convicts organized into units of 5-10 men

• Infantry units were trained to fight in close formation, using shield walls and coordinated maneuvers to overwhelm their opponents
• The Qin also made use of specialized units such as archers, engineers, and sappers to provide additional firepower and tactical flexibility

Cavalry and chariots

• In addition to infantry, the Qin military also made use of cavalry and chariots for scouting, flanking, and shock attacks
• Qin cavalry were armed with bows and spears and trained to fight in small, mobile units that could harass and disrupt enemy formations
• Chariots were used primarily by officers and nobles as command vehicles and symbols of status, but they also provided a mobile platform for archers and spearmen
• The combination of infantry, cavalry, and chariots gave the Qin military a versatile and effective force that could adapt to different battlefield conditions

Defensive fortifications and Great Wall

• The Qin dynasty was also known for its extensive use of defensive fortifications, including walls, towers, and trenches
• The most famous of these was the Great Wall, a series of fortifications that stretched for thousands of miles along China's northern border
• The Great Wall was designed to protect against nomadic invasions from the steppes and to serve as a symbol of Qin power and authority
• Other defensive works included the Epang Palace, a massive complex of walls and towers that served as the imperial residence and administrative center
• The Qin's emphasis on defense reflected their concern with maintaining order and control over their newly conquered territories

Fall of Qin dynasty

• Despite its many achievements, the Qin dynasty was relatively short-lived, lasting only 15 years before collapsing in the face of widespread rebellion and internal strife
• The fall of the Qin was brought about by a combination of factors, including the death of Qin Shi Huang, popular discontent with Qin policies, and the rise of rival contenders for power
• The collapse of the Qin dynasty marked the end of China's first imperial experiment and set the stage for the rise of the Han dynasty

Death of Qin Shi Huang

• Qin Shi Huang died in 210 BCE while on a tour of his empire, leaving his young son Huhai to succeed him as the Second Emperor
• Huhai, who was only 21 years old and had little experience in government, was easily manipulated by his advisors and quickly lost control of the empire
• The death of Qin Shi Huang created a power vacuum that was exploited by rival factions and ambitious generals, who began to plot against the Qin government

Uprisings and rebellions

• The harsh policies and heavy taxation of the Qin dynasty had created widespread resentment and discontent among the population, which erupted into open rebellion after Qin Shi Huang's death
• Peasant uprisings and military mutinies broke out across the empire, led by charismatic leaders such as Chen Sheng and Wu Guang
• These rebellions quickly spread and overwhelmed the Qin government, which was weakened by internal power struggles and a lack of popular support
• The most successful of these rebellions was led by Xiang Yu, a former Qin general who declared himself the "Hegemon-King of Western Chu" and sought to overthrow the Qin dynasty

Overthrow by Liu Bang and establishment of Han dynasty

• The final blow to the Qin dynasty came from Liu Bang, a peasant leader who had risen to become a powerful warlord during the rebellion
• Liu Bang allied himself with Xiang Yu to defeat the Qin army and capture the capital of Xianyang in 206 BCE
• However, Liu Bang and Xiang Yu soon turned against each other in a struggle for power known as the Chu-Han Contention
• After several years of fighting, Liu Bang emerged victorious and declared himself the first emperor of the Han dynasty in 202 BCE
• The Han dynasty would go on to rule China for over 400 years, building on many of the institutions and policies established by the Qin while also introducing important reforms and innovations
