Neil MacGregor charts the career of Otto von Bismarck (1815-98), known as the Iron Chancellor: he argued that the great questions of the day should be decided by 'iron and blood'.

Bismarck was disliked and feared by foreigners, and reviled by liberals at home for his authoritarianism, but among many sections of the German population, he was a hero.

At his death, monuments were erected across the whole country by public subscription, but Bismarck could also be brought into your own home. Small statues of Bismarck came in many guises, but few are more striking than the little bronze and plaster figure belonging to the German Historical Museum in Berlin, showing Bismarck the Blacksmith. Bald-headed, sleeves rolled up, wearing a leather apron and wielding his hammer, the middle-aged Bismarck is at his forge, the trusty village blacksmith.
