Is the Brexit vote nostalgia for the bygone glories of the British Empire?
After Thursday's Brexit vote, the Remain side is emerging from its state of shock, and the euphoria is starting to fade for the triumphant Leave side.
She tells Michael Enright that a nostalgic yearning for a simpler time that never really existed, and fading memories of the two world wars both contributed to the vote in favour of leaving the European Union.
[The] memories of the war and the vicious nationalist passions that caused the war really have begun to fade. And so you have people now who don't really remember why Europe was important.- Margaret MacMillan
The Leave campaign was littered with references to Churchill, the Dunkirk spirit, and the glory of the Elizabethan age. But MacMillan says the campaign relied on "very distorted history" and was fuelled by anxieties about loss of empire and influence on the world stage.
One of the things that kept being said in the whole campaign by the Euroskeptics was that as soon as we free ourselves from the shackles of Europe, we will soar again as a rising power, and we'll resume our rightful place as leader of the Anglo-sphere.- Margaret MacMillan
Those who voted 'Leave' expecting Britain to regain power and influence with English-speaking countries like Canada may be in for a rude awakening when they realize the rest of the world has moved on, she says.
"You get these people standing up at meetings saying, We just want our country back. What they mean by that, I think, is probably a simpler time, a time when you had your cup of tea and your digestive biscuit and there weren't any funny foreigners around. But life never was simple in the past," MacMillan says.
"Nostalgia is a dangerous thing, because it sort of has this hazy golden view of what things were like in the past, which is often very, very partial."
