text: When we closely examine history’s most impactful leaders, we often find common traits like boldness, eloquence, and creativity. But what about those characteristics that aren’t necessarily as celebrated?
  Indeed, a more detailed appraisal reveals a darker side to the pinnacle of leadership attained by so few. Let’s take a look at these unforgettable leaders who have not only gone to battle to create their idea of a perfect polity, but also went to battle with themselves, internally waging war with mental illness:
  Abraham Lincoln, the 16th President of the United States, suffered from episodes of depression throughout his life (described by one friend as bouts of profound melancholy). In one instance, he was rumored to have been found wandering the woods with a shotgun following the death of a close friend.Wikimedia Commons
  Joseph Stalin was the leader of the USSR from the 1920s to 1953. He ruled through terror, murdering millions of his own citizens. If he had been evaluated by today’s mental health standards, he very likely would have been diagnosed with narcissistic personality disorder, paranoid personality disorder, and manic depression.Wikimedia Commons
  Martin Luther King, Jr.
  It's hard to find a more passionate and expressive leader than Martin Luther King, Jr. Still, King suffered through dark days. The civil rights leader experienced severe depressive episodes well into adulthood following two reported suicide attempts as an adolescent. Even after his rise to prominence as a human rights activist, his staff urged him to seek psychiatric treatment, which he refused.Wikimedia Commons
