By the Eastern Han period, local elites of unattached scholars, teachers, students, and government officials began to identify themselves as members of a larger, nationwide

socioeconomic status between that of owner-cultivator farmers and common
merchants.
State-registered merchants, who were forced by law to wear white-colored clothes and pay high commercial taxes, were considered by the gentry as social parasites with a contemptible status. These were often petty shopkeepers of urban marketplaces; merchants such as industrialists and itinerant traders working between a network of cities could avoid registering as merchants and were often wealthier and more powerful than the vast majority of government officials.
Wealthy landowners, such as nobles and officials, often provided lodging for retainers who provided valuable work or duties, sometimes including fighting bandits or riding into battle. Unlike slaves, retainers could come and go from their master's home as they pleased.

Confucian family norms, various family members were treated with different levels of respect and intimacy. For example, there were different accepted time frames for mourning the death of a father versus a paternal uncle.

primogeniture; each son received an equal share of the family property. Unlike the practice in later dynasties, the father usually sent his adult married sons away with their portions of the family fortune. Daughters received a portion of the family fortune through their
marriage dowries, though this was usually much less than the shares of sons. A different distribution of the remainder could be specified in a
will, but it is unclear how common this was.
Women were expected to obey the will of their father, then their husband, and then their adult son in old age. However, it is known from contemporary sources that there were many deviations to this rule, especially in regard to mothers over their sons, and empresses who ordered around and openly humiliated their fathers and brothers.

sorceresses, respected medical physicians, and successful merchants who could afford their own silk clothes. Some women formed spinning collectives, aggregating the resources of several different families.

However, state organs with competing interests and institutions such as the court conference (''tíngyì'' )—where ministers were convened to reach
majority consensus on an issue—pressured the emperor to accept the advice of his ministers on policy decisions. If the emperor rejected a court conference decision, he risked alienating his high ministers. Nevertheless, emperors sometimes did reject the majority opinion reached at court conferences.

The Chancellor, whose title was changed to 'Minister over the Masses' in 8 BC, was chiefly responsible for drafting the
government budget. The Chancellor's other duties included managing provincial registers for land and population, leading court conferences, acting as judge in lawsuits, and recommending nominees for high office. He could appoint officials below the salary-rank of 600 bushels.
The Imperial Counselor's chief duty was to conduct disciplinary procedures for officials. He shared similar duties with the Chancellor, such as receiving annual provincial reports. However, when his title was changed to Minister of Works in 8 BC, his chief duty became the oversight of public works projects.
The Grand Commandant, whose title was changed to Grand Marshal in 119 BC before reverting to Grand Commandant in 51 AD, was the irregularly posted commander of the military and then

The Minister of Ceremonies (''Tàicháng'' ) was the chief official in charge of religious rites, rituals, prayers, and the maintenance of ancestral temples and altars. The Minister of the Household (''Guāng lù xūn'' ) was in charge of the emperor's security within the palace grounds, external imperial parks, and wherever the emperor made an outing by chariot.
The Minister of the Guards (''Wèiwèi'' ) was responsible for securing and patrolling the walls, towers, and gates of the imperial palaces. The Minister Coachman (''Tàipú'' ) was responsible for the maintenance of imperial stables, horses, carriages, and coach-houses for the emperor and his palace attendants, as well as the supply of horses for the armed forces. The Minister of Justice (''Tíngwèi'' ) was the chief official in charge of upholding, administering, and interpreting the law. The Minister Herald (''Dà hónglú'' ) was the chief official in charge of receiving honored guests at the imperial court, such as nobles and
foreign ambassadors.
The Minister of the Imperial Clan (''Zōngzhèng'' ) oversaw the imperial court's interactions with the empire's nobility and extended imperial family, such as granting fiefs and titles. The Minister of Finance (''Dà sìnóng'' ) was the

(''li'' 里), each containing about a hundred families.
The heads of provinces, whose official title was changed from Inspector to Governor and vice versa several times during Han, were responsible for inspecting several commandery-level and kingdom-level administrations. On the basis of their reports, the officials in these local administrations would be promoted, demoted, dismissed, or prosecuted by the imperial court.
A governor could take various actions without permission from the imperial court. The lower-ranked inspector had executive powers only during times of crisis, such as raising militias across the commanderies under his jurisdiction to suppress a rebellion.
A commandery consisted of a group of counties, and was headed by an Administrator. He was the top civil and military leader of the commandery and handled defense, lawsuits, seasonal instructions to farmers, and recommendations of nominees for office sent annually to the capital in a quota system first established by Emperor Wu. The head of a large county of about 10,000 households was called a Prefect, while the heads of smaller counties were called Chiefs, and both could be referred to as

Kingdoms and marquessates
Kingdoms—roughly the size of
commanderies—were ruled exclusively by the emperor's male relatives as semi-autonomous
fiefdom
A fief (; la, feudum) was a central element in medieval contracts based on feudal law. It consisted of a form of property holding or other rights granted by an overlord to a vassal, who held it in fealty or "in fee" in return for a form of f ...
s. Before 157 BC some kingdoms were ruled by non-relatives, granted to them in return for their services to Emperor Gaozu. The administration of each kingdom was very similar to that of the central government. Although the emperor appointed the Chancellor of each kingdom, kings appointed all the remaining civil officials in their fiefs.
However, in 145 BC, after several insurrections by the kings, Emperor Jing removed the kings' rights to appoint officials whose
salaries were higher than 400 bushels. The Imperial Counselors and Nine Ministers (excluding the Minister Coachman) of every kingdom were abolished, although the Chancellor was still appointed by the central government.
With these reforms, kings were reduced to being nominal heads of their fiefs, gaining a personal income from only a portion of the taxes collected in their kingdom. Similarly, the officials in the administrative staff of a full marquess's fief were appointed by the central government. A marquess's Chancellor was ranked as the equivalent of a county Prefect. Like a king, the marquess collected a portion of the tax revenues in his fief as personal income.
Up until the reign of
Emperor Jing of Han, the Emperors of the Han had great difficulty bringing the vassal kings under control, as kings often switched their allegiance to the
Xiongnu

Chanyu whenever threatened by Imperial attempts to centralize power. Within the seven years of Han Gaozu's reign, three vassal kings and one marquess either defected to or allied with the Xiongnu. Even imperial princes in control of fiefdoms would sometimes invite the Xiongnu to invade in response to threats by the Emperor to remove their power. The Han emperors moved to secure a treaty with the Chanyu to demarcate authority between them, recognizing each other as the "two masters" (兩主), the sole representatives of their respective peoples, and cemented it with a marriage alliance (''

''), before eliminating the rebellious vassal kings in 154 BC. This prompted some vassal kings of the Xiongnu to switch their allegiance to the Han emperor from 147 BC. Han court officials were initially hostile to the idea of disrupting the status quo and expanding into the Xiongnu steppe territory. The surrendered Xiongnu were integrated into a parallel military and political structure under the Han Emperor, and opened the avenue for the Han dynasty to challenge the Xiongnu cavalry on the steppe. This also introduced the Han to the interstate networks in the Tarim Basin (Xinjiang), allowing for the expansion of the Han dynasty from a limited regional state to a universalist and cosmopolitan empire through further marriage alliances with another steppe power, the

Military
At the beginning of the Han dynasty, every male commoner aged twenty-three was liable for
conscription into the military. The minimum age for the military draft was reduced to twenty after
Emperor Zhao's ( BC) reign. Conscripted soldiers underwent one year of training and one year of service as non-professional soldiers. The year of training was served in one of three branches of the armed forces:

. Soldiers who completed their term of service still needed to train to maintain their skill because they were subject to annual military readiness inspections and could be called up for future service - until this practice was discontinued after 30 AD with the abolishment of much of the conscription system. The year of active service was served either on the frontier, in a king's court, or under the Minister of the Guards in the capital. A small professional (full time career) standing army was stationed near the capital.
During the Eastern Han, conscription could be avoided if one paid a commutable tax. The Eastern Han court favored the recruitment of a

When central authority collapsed after 189 AD, wealthy landowners, members of the aristocracy/nobility, and regional military-governors relied upon their retainers to act as their own personal troops. The latter were known as 部曲, a special social class in Chinese history.

government mint in favor of private minting of coins. This decision was reversed in 186 BC by his widow

(618–907 AD). Its use was interrupted briefly by several new currencies introduced during Wang Mang's regime until it was reinstated in 40 AD by Emperor Guangwu.
Since commandery-issued coins were often of inferior quality and lighter weight, the central government closed commandery mints and monopolized the issue of coinage in 113 BC. This central government issuance of coinage was overseen by the
Superintendent of Waterways and Parks, this duty being transferred to the Minister of Finance during the Eastern Han.
Taxation and property
Aside from the landowner's
land tax paid in a portion of their
crop yield, the
poll tax and
property tax

es were paid in coin cash. The annual poll tax rate for adult men and women was 120 coins and 20 coins for minors. Merchants were required to pay a higher rate of 240 coins. The poll tax stimulated a money economy that necessitated the minting of over 28,000,000,000 coins from 118 BC to 5 AD, an average of 220,000,000 coins a year.
The widespread circulation of coin cash allowed successful merchants to invest money in land, empowering the very social class the government attempted to suppress through heavy commercial and property taxes. Emperor Wu even enacted laws which banned registered merchants from owning land, yet powerful merchants were able to avoid registration and own large tracts of land.
The small landowner-cultivators formed the majority of the Han tax base; this revenue was threatened during the latter half of Eastern Han when many peasants fell into debt and were forced to work as farming tenants for wealthy
landlord
A landlord is the owner of a house, apartment, condominium, land, or real estate which is rented or leased to an individual or business, who is called a tenant (also a ''lessee'' or ''renter''). When a juristic person is in this position, t ...
s. The Han government enacted reforms in order to keep small landowner-cultivators out of debt and on their own farms. These reforms included reducing taxes, temporary remissions of taxes, granting loans, and providing landless peasants temporary lodging and work in
agricultural colonies until they could recover from their debts.
In 168 BC, the land tax rate was reduced from one-fifteenth of a farming household's crop yield to one-thirtieth, and later to a one-hundredth of a crop yield for the last decades of the dynasty. The consequent loss of government revenue was compensated for by increasing property taxes.
The labor tax took the form of
conscripted labor for one month per year, which was imposed upon male commoners aged fifteen to fifty-six. This could be avoided in Eastern Han with a commutable tax, since hired labor became more popular.
Private manufacture and government monopolies
In the early Western Han, a wealthy salt or iron industrialist, whether a semi-autonomous king or wealthy merchant, could boast funds that rivaled the imperial

and amass a peasant workforce of over a thousand. This kept many peasants away from their farms and denied the government a significant portion of its land tax revenue. To eliminate the influence of such private entrepreneurs, Emperor Wu nationalized the salt and iron industries in 117 BC and allowed many of the former industrialists to become officials administering the state monopolies. By Eastern Han times, the central government monopolies were repealed in favor of production by commandery and county administrations, as well as private businessmen.
Liquor was another profitable private industry nationalized by the central government in 98 BC. However, this was repealed in 81 BC and a property tax rate of two coins for every 0.2 L (0.05 gallons) was levied for those who traded it privately. By 110 BC Emperor Wu also interfered with the profitable trade in grain when he eliminated
speculation by selling government-stored grain at a lower price than that demanded by merchants. Apart from Emperor Ming's creation of a short-lived Office for Price Adjustment and Stabilization, which was abolished in 68 AD, central-government price control regulations were largely absent during the Eastern Han.

Mechanical and hydraulic engineering
Han-era mechanical engineering comes largely from the choice observational writings of sometimes-disinterested Confucian scholars who generally considered scientific and engineering endeavors to be far beneath them. Professional artisan-engineers (''jiang'' 匠) did not leave behind detailed records of their work. Han scholars, who often had little or no expertise in mechanical engineering, sometimes provided insufficient information on the various technologies they described. Nevertheless, some Han literary sources provide crucial information.
For example, in 15 BC the philosopher and poet
Yang Xiong described the invention of the
belt drive for a
