According to the NGO Freedom House, even though the number of dictatorships has dwindled, there remain 106 in the world. At BBC Future, Rachel Nuwer examines the personality traits and political conditions that allow such authoritarian governments to exist and wonders if we’ll ever live in a dictator-less world. An excerpt:

The causative factors that give rise to dictatorships in the first place have not changed much over the centuries. Some of the first were established in Classical Rome in times of emergencies. “A single individual like Julius Caesar was given a lot of power to help society cope with a crisis, after which that power was supposed to be relinquished,” says Richard Overy, a historian at the University of Exeter. “But usually, he wasn’t so keen to relinquish it.” Many modern and recent dictatorships – those of Adolf Hitler and Benito Mussolini, for instance – were also established in times of turmoil, and future ones likely will be, too. “Over the next century, there will be acute points of crisis,” Overy says. “I don’t think we’ve seen the end of dictatorship any more than we’ve seen the end of war.”  

But just as violence on a whole has declined across history, so, too, has the number of dictatorships, especially since the 1970s, as regimes across Latin America and Eastern Europe fell. There are slight undulations; the crumbling of the Soviet Union was accompanied by a steep decline in dictatorships, but now many of those countries are creeping back toward that former mode of governance. Overall, though, dictatorships are scarcer now than they were in the past. “It’s harder for people to justify dictatorships today, partly because the whole globe is in the eye of the media,” Overy says. “Getting away with things is more difficult than it used to be.”   

Consequently, days might be numbered on at least some remaining dictatorships – particularly if their oppressive rule is contributing to home-grown economic problems. “When you’re operating in an economy that’s perpetuating your collapse, your backers become nervous that you won’t be able to help them, so they start to shop around,” [NYU professor Bruce] Bueno de Mesquita says. Such situations sometimes result in military coups, he adds, which tend to push countries in a more positive direction for citizen wellbeing, at least based on past examples.

Some dictatorships, however, show no signs of cracking.•
