he question of empire has become central to discussions of Britain’s national past. Some see residual imperialism as the prime element in a deficient, delusional, racist culture. Others think emphasising the dark underside of empire is an attempt to erase British history. The problem is that although long historical tradition sanctions criticism of imperialism, national history has proved far more resistant. Talk of empire is now omnipresent, but it was previously written out of history. In the 1940s the unashamed imperialist Winston Churchill didn’t offer an imperial history of the second world war, or even a national one, but an Anglo-American, cold-war version of events in his six-volume work, The Second World War. Subsequently, what’s striking about postwar historiography is the lack of imperialist histories and the absence of condemnation for nationalist and anti-imperial forces. At most there were sotto voce claims that the British empire should have done a deal with Adolf Hitler in 1940 to keep itself alive. More importantly, national histories ignored empire altogether. The reason is easy to find: after the war, a new nation arose that wanted to tell a national, not imperial, history of itself. This story was about the dawn of the welfare state, the Labour party and the National Health Service. This country’s ancestry lay in the industrial 19th century, but it only became a true nation in 1940, during the Battle of Britain and the blitz. Putting the empire in its proper historical place is hugely important for understanding the sheer scale of slavery, the racialised nature of the imperial project, and how this project shaped the Conservative party into the 1950s. For much of the elite, the UK was seen as a part of something far bigger: the empire. This is why we have an Imperial War Museum and an Imperial College, and why the head of the army was called the chief of the imperial general staff. Britain’s second world war, as it was understood at the time, involved the whole British empire (and many, many allies). In 1940, no one in authority could say “Britain stood alone”. If anything was alone, it was the entire empire. It’s also important to remember the important role anti-imperialism played for radical liberals and socialists. Radical liberals in 19th-century Britain criticised imperialism as the cause of unnecessary wars, and for sustaining a useless elite. More recently, the British centre-left has cited imperialism as the cause of war, militarism, nuclear weapons, economic decline, the failure to join the common market in the 1950s, and the failure to adapt to it since. For some historians, the demons and ghosts of empire are the spectres driving contemporary racism and Brexit, too. The UK, according to these critics, seems perpetually trapped in an Edwardian imperial mindset. Blaming empire is a deep-seated reflex that feels reassuringly progressive. But it has also been a way to avoid confronting things that lie a little closer to home. It has long been easier, and less morally and intellectually contentious, to castigate the actions of the British state and elite in faraway colonies than confront their actions at home. Far too many ills of past and present are lazily laid at this door. To make empire the dominant story in British history is to misunderstand the nature of Britain, its elite and its exploitative power, and its persistent racism. The racism of Oswald Mosley and Enoch Powell, for all its roots in the past, was a self-consciously post-imperial nationalist one. Imperialism reluctantly granted British Caribbean people UK citizenship. These rights were stripped away by nationalists, right down to Theresa May – this was the essence of the Windrush scandal. People voted for Brexit not because they were imperialists, but because they were nostalgic for a national Britain. They were certainly not voting for the return to free immigration from the old imperial territories. The history that seems to matter most to Brexiteers is a particular account of the second world war, one that is decidedly nationalist. Empire has only ever been part of the British story, but it can never stand for the whole. Even at its peak, it represented only a fraction of Britain’s relations with the rest of the world, not least in war, but also in trade. From the late 19th century onwards, the Caribbean empire was tiny in terms of trade and population compared with Canada and Australia. In population numbers, India accounted for four-fifths of the entire empire, but trade with India was significantly less important than trade with the dominions. And the history of migration to and from the UK stretches wider than the empire, too – with people flowing into and out of the country to the US and from Europe. Britain’s global history, in other words, is not the same as its imperial history. If we want to look for great silences in our history, empire is hardly the only one. There has been a glaring hole where the history of British capitalism and the British capitalist class should be; in its place are overwrought stories of decline and of imperial finance. The neglect of the British working class is particularly stunning. Giants of (anti-imperialist) postwar history such as EP Thompson and Eric Hobsbawm made this their field, and inspired countless others in a historical endeavour that peaked in the 1970s, but has since decayed even more rapidly than the industrial working class. Around 1900, Britain’s industrial proletariat was one of the three largest in the world, comparable to those of the US and Germany. The British working class alone accounted for roughly 30% of the population of the entire empire outside India, and a far higher proportion of those producing for capitalist markets. There are many aspects of British history – many dark sides, too – other than imperialism. We should not admit the framing of the debate about history as a question of a dark imperial history sullying a bright national story. To do so would be to ignore a more difficult truth: all our national history needs rethinking. • David Edgerton is the author of The Rise and Fall of the British Nation: a Twentieth-Century History
