Thatcher's second and third terms (1983–87 and 1987–90) saw the most radical transformation of the British state and economy since the Attlee government — the period in which the rhetoric of the first term became sweeping reality. Privatisation transferred the great nationalised industries to private shareholders; the defeat of the miners in 1984–85 broke the power of the union that had destroyed Heath; the deregulation of the City ("Big Bang") remade British capitalism; and Right to Buy created millions of new homeowners. The same years brought rising inequality, the abolition of the Greater London Council, the divisive Section 28, and finally the poll tax, whose unpopularity helped to destroy Thatcher herself in November 1990.
This is the period in which "Thatcherism" took its mature shape, and it is the richest terrain in the whole course for the central historiographical question: was Thatcherism a necessary economic modernisation that rescued Britain from decline, or an ideologically driven assault on the post-war settlement that enriched some while devastating others? The lesson examines the three great pillars — the union confrontation, privatisation, and social transformation — and the contested legacy they created.
Key Question: How far did Thatcher's governments of 1983–1990 transform Britain's economy and society, and was that transformation a necessary modernisation or an ideologically driven and socially divisive revolution?
Key Definition: Privatisation — the sale of state-owned industries and assets to private investors, transforming a mixed economy with extensive public ownership into a predominantly private one. The defining domestic policy of Thatcherism, it was largely unforeseen in 1979 and developed in scope across the 1980s.
This lesson sits within Part Two of Paper 2, Option 2S — The Making of Modern Britain, 1951–2007 ("The Impact of Thatcherism and Beyond, 1979–2007"). As a depth study, examiners reward precise command of the privatisation programme (which industries, when, for how much), the chronology of the miners' strike, and the detail of the poll tax and Thatcher's fall — all analysed through second-order concepts.
The miners' strike of 1984–85 was the defining industrial confrontation of the late twentieth century — a deliberate test of strength between the government and the union that had broken Heath, which Thatcher was determined to win. Her caution in 1981, when she had retreated rather than fight with coal stocks low, had been a tactical delay; by 1984 the ground had been carefully prepared.
| Preparation | Detail |
|---|---|
| Ridley Plan | Nicholas Ridley's confidential 1977 report (leaked to The Economist in 1978) had set out how to defeat a future miners' strike: build up coal stocks, arrange to import coal, recruit non-union road hauliers, train and equip a large mobile police force, and use the law to cut off union funds |
| Ian MacGregor | Appointed chairman of the National Coal Board in 1983 — a tough American-based Scottish industrialist who had overseen heavy redundancies at British Steel |
| Coal stocks | The government had built up large stockpiles at power stations — directly remedying the critical weakness that had lost the 1972 and 1974 strikes |
| Employment Acts | The legal framework (Employment Acts 1980, 1982; Trade Union Act 1984) had already restricted secondary picketing and required ballots — weapons the state could now deploy |
| Phase | Events |
|---|---|
| Trigger | The NCB announced the closure of Cortonwood colliery (Yorkshire) on 1 March 1984, part of a wider closure plan; area strikes began at once |
| National strike without a ballot | Arthur Scargill, NUM president, called a national strike from 12 March 1984 without holding a national ballot — a fateful decision that handed the government a propaganda weapon, divided the union, and enabled the Nottinghamshire coalfield (later the breakaway Union of Democratic Mineworkers) to keep working |
| Mass picketing and Orgreave | The dispute turned on mass picketing of working pits and installations. The "Battle of Orgreave" (18 June 1984), where mounted police charged pickets at a coking plant near Sheffield, became its violent symbol; the policing — coordinated nationally, heavily resourced — was later condemned by critics as disproportionate and politicised |
| Endurance and hardship | The strike lasted almost exactly a year amid acute hardship in mining communities, sustained by extraordinary solidarity (and by support groups, notably the Women Against Pit Closures movement and, famously, Lesbians and Gays Support the Miners) |
| Defeat | The miners returned to work on 3 March 1985 without an agreement. The closure programme proceeded relentlessly — the number of working pits collapsed over the following decade, and the coalfields' communities were devastated |
Historiographical anchor. Raphael Samuel (ed., The Enemy Within, 1986) recorded the strike from within the mining communities, emphasising their solidarity and the social devastation of closures. Francis Beckett and David Hencke (Marching to the Fault Line, 2009) argue that Scargill's refusal to hold a ballot was a fatal strategic blunder that split the union and surrendered the moral high ground. Seumas Milne (The Enemy Within, 1994; rev. 2004) exposed the role of the security services in surveilling and undermining the NUM, raising questions about the extent of state involvement. The debate over whether the miners were defeated by Scargill's errors, by the government's meticulous preparation, or by the covert power of the state is central.
A Paper 2 Section A enquiry here might ask you to assess sources on, for example, the reasons for the defeat of the miners, or the impact of privatisation. Two especially examinable source types are the rival official statements of the dispute (an NUM or Scargill speech set against an NCB or government statement) and the privatisation advertising or financial-press coverage of the share sales.
How to evaluate them:
A firm integrity rule: characterise sources by kind and function, weigh value and limitation, and never invent an attributed quotation. Where exact wording is uncertain, summarise the argument and analyse the provenance.
The historiography of Thatcher's middle and late terms is the most polarised in the course, and a strong answer sets real historians in genuine opposition.
To evaluate: Moore's authorised case is indispensable for the argument that the union confrontation was a necessary restoration of governability, but it tends to read success backwards and to discount the social devastation that Samuel and Beckett document. Vinen's emphasis on unintended consequences is the most useful single corrective for a depth-study answer, since it resists both the triumphalist and the demonological framings — Thatcherism produced outcomes (a financialised, more unequal, home-owning but housing-short Britain) that were as much accident as design. Evans's stress on pragmatism similarly tempers the myth of a coherent master-plan. The most defensible judgement treats the transformation as real and in some respects modernising, but also as socially divisive and shot through with consequences its authors neither foresaw nor intended.
Privatisation — the sale of state-owned industries to private shareholders — was Thatcher's most enduring domestic legacy. It began cautiously and accelerated dramatically:
| Company | Date | Details |
|---|---|---|
| British Telecom | November 1984 | The first major privatisation; shares were heavily oversubscribed. The sale raised £3.9 billion. 2.3 million small shareholders applied — more than had ever bought shares in a single company |
| British Gas | December 1986 | "Tell Sid" advertising campaign encouraged small shareholders. Raised £5.6 billion |
| British Airways | February 1987 | Raised £900 million |
| British Steel | December 1988 | Raised £2.5 billion |
| Water authorities | December 1989 | Ten regional water companies privatised. Raised £5.2 billion. More controversial — privatising a natural monopoly and essential public service |
| Electricity | December 1990 | Distribution companies sold; generation companies followed in 1991. Raised £5.2 billion |
The deregulation of the London Stock Exchange — known as the "Big Bang" — transformed the City of London:
| Change | Detail |
|---|---|
| Fixed commissions | Abolished — introducing competition in brokerage fees |
| Single capacity | The distinction between jobbers (market-makers) and brokers was abolished |
| Foreign ownership | Foreign firms were permitted to buy British brokerages and market-makers |
| Electronic trading | The trading floor was replaced by electronic screen-based trading |
The Big Bang made London one of the world's leading financial centres but also contributed to the culture of financial excess and risk-taking that would culminate in the 2008 financial crisis. The motives for privatisation were mixed, and recognising this is a mark of sophistication: ideology (a genuine belief in private over public ownership and in "popular capitalism") combined with pragmatic fiscal advantage (the sales raised tens of billions that flattered the public finances), the desire to discipline overmighty public-sector unions, and the political calculation that millions of new shareholders and homeowners would become natural Conservatives. Eric Evans's emphasis on the pragmatic and improvised character of the programme — it was barely mentioned in 1979 and grew opportunistically — is a useful corrective to any view of privatisation as a fully pre-formed ideological blueprint.
The Housing Act 1980 gave council tenants the right to buy their homes at substantial discounts (33–50% depending on length of tenancy, later increased to 60–70%):
| Aspect | Detail |
|---|---|
| Scale | Approximately 1.5 million council homes were sold between 1980 and 1990 |
| Impact | Created a new class of homeowners; receipts were not used to build replacement social housing, contributing to a long-term housing shortage |
| Political significance | Right to Buy was enormously popular with working-class voters — it embodied Thatcher's vision of a "property-owning democracy" and helped the Conservatives win votes in traditionally Labour constituencies |
