The Brexit referendum was dominated by simplistic visions of the European Union. Critics portrayed the EU as vacuuming money out of the UK to support an overweening Brussels bureaucracy, while Remain supporters appeared tongue-tied in making a positive case to stay in the EU.
      
    
    
       Drawing on a new book, Richard Pomfret 
argues the process of European economic integration has alternated 
between periods of reform and apparent gridlock, but with substantial 
cumulative change over the last 75 years. At each major step, the UK 
hesitated or followed a false trail.
For Belgium, France, Germany, Italy, Luxembourg and the Netherlands, 
economic integration was an instrument for preventing renewed war in 
Europe. The project has been successful. In the 75 years up to 1945, 
Europe suffered three increasingly devastating Franco-German wars; in 
the 75 years after 1945, France and Germany co-existed peacefully
In a recently published book,
 I argue that European integration has been an evolutionary process, 
using economic integration as a means of promoting political harmony. 
Or, if harmony is too strong a word for an institution often 
characterised by dissent before agreement on a path forward, a means of 
maintaining peace in Europe. Member governments have been cautious in 
resisting change that might negatively impact perceived national 
interest, but ultimately have reached agreement on how to proceed.
The purpose and nature of European economic integration has been 
viewed differently in England. For London, economic integration was 
about balancing economic costs and benefits, and avoiding ceding too 
much sovereignty. At each major stage in European economic integration, 
the UK was out of step, either reluctant to participate or pushing its 
own priority.
The original six members started with a limited sectoral agreement 
before agreeing in the Treaty of Rome in 1957 to set up a customs union.
 The UK stayed away. The customs union took a decade to establish, 
including a convoluted special regime for agriculture. As an alternative
 to the customs union, the UK set up a free trade area with six other 
countries. Without a common external trade policy and excluding 
agriculture, the free trade area was simpler than the customs union. 
However, the most dynamic western European economies were in the customs
 union.
The UK abandoned the free trade area and joined the customs union in 
1973. In less than a decade, Margaret Thatcher was complaining about the
 UK’s positive net contribution to the budget and fighting to get 
Britain’s money back. The idea that contributions should be balanced was
 not accepted by other members. They preferred to address UK concerns by
 reform, reducing the share of spending on agriculture and increasing 
funding for poorer regions of Europe and other common projects.
By the early 1980s, the integration project was in difficulty. 
Members used non-tariff barriers to get around the internal free 
movement of goods in the customs union, and little progress had been 
made on free movement for services, labour, or capital. Margaret 
Thatcher’s budget struggles alienated other members who out-manoeuvred 
her in passing the Single European Act in 1986. The members agreed to 
strengthen economic integration by creating a single market.
Thatcher initially supported creation of a single market, of which 
her ally Lord Cockfield was the principal architect, but dramatically 
reversed her position when it became apparent that the single market 
might include adoption of a single currency. That was too great an 
invasion of UK sovereignty. By then, it was too late, and Thatcher’s 
obduracy contributed to her losing her job. The single market was 
codified in the 1993 Maastricht Treaty and followed by creation of the 
euro. The Maastricht Treaty was passed with lukewarm acquiescence of 
Thatcher’s successors who demanded opt-outs from the social charter and 
the common currency – and amid strong opposition from Eurosceptics in 
the Conservative party.
All the signs are that the EU is here to stay, whatever its future evolution.
The EU in the 21st century differed from the European 
Communities of the 1970s not just in depth of integration but also in 
expansion from 12 to 28 members. The situation required new rules on 
decision-making, formalised in the 2007 Treaty of Lisbon. Although the 
UK was generally supportive of enlargement, Eurosceptics were cautious 
about the deeper integration set out in the Lisbon Treaty, despite 
increased emphasis on subsidiarity. Brexit was not inevitable, but the 
battle lines were being drawn....
