It may be because I’m a professional historian, and so proprietorial towards my subject, but I’ve always objected to British history’s being used – ‘prostituted’, would be my word for it – in order to inculcate patriotism, as Theresa May’s latest idea for a citizenship test for immigrants seeking British nationality appears to envisage. For a start it must be questionable how far our history ‘defines’ us as a nation, as opposed to our present-day circumstances, and influences from abroad. Second, history taught in order to teach patriotism must be ‘patriotic’ history, which is bound to be selective at best. Third, I rather like the Swedes’ view of their national identity, which is defined much more in terms of their aspirations – equality, and the like – than of their history. Just as well, perhaps; Sweden has quite a number of skeletons in its historical cupboard: as of course does Britain.
