Emperor Wu of Han: expansion and reforms 141-87 BC: HSC Ancient History

A 3-mark "outline" wants the earlier policy, the turning point, and the new policy, each briefly and accurately stated.

The earlier policy (heqin)

From Gaozu's near-disaster at Baideng in 200 BC, the early Han had managed the Xiongnu confederation through heqin ("harmonious kinship"): sending imperial princesses in marriage and regular gifts of silk, grain and wine to the chanyu to buy peace on the northern frontier.

The turning point

Emperor Wu abandoned appeasement. In 133 BC he attempted the Mayi ambush, a failed plan to trap the chanyu and his army near the border town of Mayi; although the trap failed, it ended heqin and opened decades of open war.

The new policy

Wu launched repeated large-scale offensive cavalry campaigns deep into the steppe, led by generals Wei Qing and his nephew Huo Qubing, culminating in the Battle of Mobei in 119 BC, which drove the Xiongnu court north of the Gobi Desert.

Markers reward the named earlier policy (heqin), the Mayi turning point in 133 BC, and the shift to offensive war under Wei Qing and Huo Qubing.

A 4-mark "describe" wants several developed, correctly dated measures.

State monopolies on salt and iron

From around 117 BC, on the advice of finance officials led by Sang Hongyang, the state took over the production and sale of salt and iron, the two commodities every household needed, turning them into a guaranteed source of revenue independent of the land tax.

Currency reform

In 118 BC Wu introduced the standardised bronze wuzhu ("five-grain") coin, minted under central control, replacing debased and privately cast coinages and stabilising the money supply.

Equable transport and price stabilisation

In 110 BC Sang Hongyang established the junshu ("equable transport") system, which collected regional taxes in kind and moved goods to where they sold dearest, and the pingzhun ("price stabilisation") system, under which the state bought cheap and sold dear to level prices and profit from the trade.

Other expedients

Wu also briefly monopolised liquor, sold offices and ranks, and levied new taxes on merchants' property, all to feed the enormous cost of the frontier wars.

Markers reward the salt and iron monopolies, the wuzhu coin (118 BC), the equable-transport and price-stabilisation systems (110 BC), and the link back to funding the wars.

A 5-mark "explain" needs the source decoded and then supported with accurate own knowledge.

Use the source

Source A shows a finance official arguing that the profits of salt and iron ("the mountains and seas") should be taken from private producers by the state specifically so that "the campaigns against the Xiongnu may be supplied", directly tying the monopolies to the cost of the frontier wars.

Own knowledge: the real policy this reflects

This reflects the salt and iron monopolies Emperor Wu established from around 117 BC under officials such as Sang Hongyang, Kong Jin and Dongguo Xianyang, alongside the wuzhu coin of 118 BC and the equable-transport and price-stabilisation systems of 110 BC, a whole apparatus of state economic intervention built to pay for expansion.

Own knowledge: what it reveals

It reveals that Wu's expansion could not be funded from the ordinary land tax alone, so the state turned itself into a merchant and manufacturer, an interventionist fiscal policy that Michael Loewe associates with the "Modernist" faction at court and that the Confucian "Reformists" later attacked, most famously at the 81 BC Salt and Iron Debate.

Markers reward decoding the source's argument, correct identification of the real monopolies and their dates, and the point that expansion drove an interventionist fiscal state.

A 6-mark "assess" needs balanced usefulness and limitations, own knowledge, and a historian.

Content

The source has an ageing emperor rejecting a proposal for further distant campaigns (at Luntai in the Western Regions) on the ground that they "weary the empire" and do not "nurture the people", a rare note of imperial restraint and near-regret.

Usefulness

This type of evidence is genuinely useful because it reflects a documented moment: the Luntai edict of 89 BC, in which Wu declined to expand the war in Central Asia. By then decades of campaigning against the Xiongnu, in the Hexi corridor, against Dayuan (the War of the Heavenly Horses, 104-101 BC), and in Nanyue and Korea, had drained the treasury the monopolies were built to fill, provoked the property taxes on merchants, and contributed to unrest, so an edict acknowledging the human cost fits the fiscal reality.

Limitations

An edict is an official, self-justifying document preserved through the later dynastic histories (chiefly Ban Gu's Hanshu), so it presents the throne's chosen image; it may soften a lifetime of aggressive war into statesmanlike regret. It also captures a single late moment, not the reign as a whole, and historians debate how far it signals a real change of policy as opposed to a rhetorical gesture.

Historian and own knowledge

The traditional reading, going back to Ban Gu's Hanshu, takes the Luntai edict as a genuine change of heart, a turn from "Modernist" expansion towards "Reformist" retrenchment later carried through by Huo Guang after Wu's death in 87 BC, though modern historians such as Xin Deyong dispute how far it was a real turning point; either way the edict corroborates that expansion had reached the limit of what the fiscal reforms could sustain.

Markers reward balanced usefulness and limitations, the named context (the 89 BC Luntai edict and the cost of the wars), an explicit comment on the bias of an official edict preserved in later histories, and a named historian used as argument.

A 4-mark "explain" needs the mechanism, not just the label "Confucianism".

The adviser and the argument

Emperor Wu's court scholar Dong Zhongshu argued, in memorials answering the emperor's own policy questions around 134 BC, that the "hundred schools" of philosophy should be dismissed and Confucian classics alone made the basis of official learning, giving the throne a single moral vocabulary of the Mandate of Heaven and hierarchical loyalty.

The institutional steps

Wu acted on this: in 136 BC he established Erudites (boshi) dedicated to the Five Classics; in 124 BC he founded the Taixue (Imperial University) at Chang'an, beginning with about 50 students trained in the Confucian canon; and he linked office-holding to the xiaolian ("filial and incorrupt") recommendation system, so that a Confucian education became the pathway into the bureaucracy.

The reality beneath

Confucian ideology sat over administrative machinery that remained heavily Legalist, strict law, household registration and the salt and iron monopolies, a synthesis Michael Loewe calls "Confucian in appearance, Legalist in substance".

Markers reward Dong Zhongshu's role, the concrete institutions (boshi in 136 BC, the Taixue in 124 BC, xiaolian recruitment), and awareness that Legalist practice continued beneath the Confucian veneer.

A 6-mark values/limitations task needs balance, specificity, and a historian.

Origin

The Shiji was completed around 91 BC by Sima Qian, who served Emperor Wu as Grand Historian and Court Astrologer and so wrote as a near-contemporary of the reign, with access to court records and archives.

Values

Its value is exceptional: Sima Qian is a first-hand witness to Wu's court, and his account of the Xiongnu wars, of Zhang Qian's missions to the Western Regions, and of the fiscal debates gives detailed, close-range evidence for the machinery and personalities of expansion (Wei Qing, Huo Qubing, Sang Hongyang). His biographical and treatise structure preserves administrative and economic detail a simple chronicle would omit.

Limitations

Sima Qian was not a neutral observer. In 99 BC he was sentenced to castration for defending the defeated general Li Ling, a punishment authorised by Emperor Wu himself, so his portrayal of the emperor and his wars can carry personal bitterness and veiled criticism. As a Confucian-trained scholar he was also inclined to judge Wu's aggressive expansion and interventionist finance against a moral standard of frugal, benevolent rule.

Historian and corroboration

Modern scholars such as Michael Loewe treat the Shiji as indispensable but read it critically alongside Ban Gu's later Hanshu, weighing Sima Qian's proximity against his motive; the two together, cross-checked, remain the foundation for the reign.

Markers reward origin and proximity, the specific content the Shiji supplies, the explicit motive (the Li Ling affair and Sima Qian's Confucian outlook), and a named historian on how the source is used.

A band-6 essay states a judgement on "to what extent", sustains it with dated evidence, and weaves historiography. This is a PLAN plus a model paragraph.

Thesis

The statement is substantially right but one-sided. Emperor Wu's reign (141-87 BC) was genuinely the climax of the period: he broke the Xiongnu, opened the Western Regions, absorbed Nanyue and Korea, and built an interventionist fiscal and Confucian-bureaucratic state that outlasted him. But these achievements were indeed bought at ruinous cost, an emptied treasury, heavy exactions, and human suffering that Wu himself acknowledged late in life, so "expansion at a ruinous cost" captures the reign only if both halves are weighed together rather than one being used to cancel the other.

Argument line 1: the scale of expansion was real

The shift from heqin to offensive war after the Mayi attempt of 133 BC produced decisive victories, above all the Battle of Mobei in 119 BC under Wei Qing and Huo Qubing, which drove the Xiongnu north of the Gobi. Zhang Qian's missions (from 138 BC) opened the Hexi corridor and the Silk Road; Nanyue was annexed in 111 BC and Gojoseon (Korea) conquered in 108 BC. On any measure the empire reached its greatest extent.

Argument line 2: the reforms were a lasting achievement, not only a cost

To pay for the wars Wu created the salt and iron monopolies (from around 117 BC), the wuzhu coin (118 BC), and the equable-transport and price-stabilisation systems (110 BC), while Dong Zhongshu's Confucian settlement, the Erudites (136 BC) and the Taixue (124 BC), gave the state an enduring ideology and civil service. These outlived him.

Argument line 3: the cost was nonetheless ruinous

The monopolies and merchant taxes reflect a treasury drained by war; the War of the Heavenly Horses (104-101 BC) was hugely expensive; the wugu (witchcraft) crisis of 91 BC destroyed the crown prince Liu Ju; and the Luntai edict of 89 BC has Wu himself refusing further campaigns as a burden on the people. His death in 87 BC left a child emperor under Huo Guang's regency and a policy turn towards retrenchment.

Historiography

Michael Loewe frames the reign as a contest between a "Modernist" party (expansion and state monopolies, Sang Hongyang) and a "Reformist", Confucian party favouring retrenchment, with the Luntai edict traditionally read as the hinge between them, though the edict's meaning is now debated. Mark Edward Lewis treats Wu's reign as the height of Han imperial power and its overreach at once. Sima Qian, writing near-contemporaneously (and embittered after 99 BC), and Ban Gu's later Hanshu supply the evidence, each with its own slant.

Model paragraph (line 3)

The clearest sign that expansion carried a ruinous price is that the emperor who drove it ended by disowning it. Decades of campaigning, against the Xiongnu, into Ferghana in the War of the Heavenly Horses of 104 to 101 BC, and across Nanyue and Korea, had emptied the treasury that the salt and iron monopolies were built to fill and forced ever harsher taxes on merchants and the people. By 91 BC the reign was consuming itself: the wugu witchcraft terror drove the crown prince Liu Ju to his death. When, in 89 BC, officials proposed yet another distant garrison at Luntai, Wu refused in an edict lamenting that further war would only "weary the empire". On the traditional reading, that edict marks the exhaustion of the Modernist programme, the point at which even its architect conceded that expansion had reached the limit of what the reforms could sustain, though some modern historians see only a limited retrenchment on the Western Regions front.

Conclusion

Wu's reign was an age of expansion, and it was bought at a ruinous cost; but it also built institutions, the monopolies, the coinage, the Confucian bureaucracy, that endured. The verdict, therefore, is a qualified agreement: ruinous in the short term, foundational in the long term.

Marker's note: band 6 answers state a clear verdict on "to what extent", deploy precise dated evidence (133 BC, 119 BC, 118 BC, 111 BC, 108 BC, 89 BC, 87 BC), integrate at least two named historians as argument (Loewe's Modernist/Reformist frame; Lewis on overreach), and include a genuine counter-weight (the lasting reforms) rather than a one-sided list of costs.
