Across Europe, a wave of hyper-nationalist politicians is threatening to splinter the European Union, with Geert Wilders in the Netherlands and Marine Le Pen in France waiting in the wings. In the US, many Americans are still figuring out how they’re going to face the next four years of a president elected after a campaign built on racism, anti-intellectualism, misogyny and truth distortion; his suggestion of a register for Muslims horrified many. It also prompted comparisons – some of them lazy, some of them astute – between the 1930s and now.

Against this backdrop, Volker Ullrich’s timely recent account of Hitler’s rise to power, Hitler: Ascent 1889-1939, has received critical acclaim and prompted considerable debate about the historical parallels between our times and that of the pre-war period. It also raises questions about whether history can teach us how to rewrite our own script.

Ullrich, a German historian and journalist for the Hamburg broadsheet Die Zeit, based his book on decades of research. He tells me it was written between 2009 and 2013 to a background noise of extreme right movements on the rise. As a result, he says, one question became fixed in his brain: “What are the necessary social and psychological conditions that allow populists of Hitler’s ilk to gain a mass following and attain power?”

“There are certain traits you can recognize that Hitler and Trump have in common,” Ullrich says. “I would say the egomania, the total egocentricity of both men, and the inclination to mix lies and truth – that was very characteristic of Hitler.”

Like Trump, “Hitler exploited peoples’ feelings of resentment towards the ruling elite.” He also said he would make Germany great again. Ullrich also notes both men’s talent at playing the media, making use of new technology and their propensity for stage effects.

Ullrich, however, is keen to highlight how they differ. “I think the differences are still greater than the similarities,” he says. “Hitler was not only more intelligent, but craftier. He was not just a powerful orator, but a talented actor who succeeded in winning over various social milieus. So not just the economically threatened lower middle classes which Trump targeted, but also the upper middle classes. Hitler had many supporters in the German aristocracy.” ...
