Three and a half years ago, with Donald Trump the new occupant of the White House, we began a regular section in The Sun called “One Nation, Indivisible.”

Every month since then we have dug into our archives, looking for writing to remind us that this 244-year experiment in democracy has never been easy, and that dire threats from people in power are nothing new. With excerpts from interviews, essays, and stories going back to The Sun’s founding in 1974, we’ve tried to give readers a perspective on the past and the courage to face the future.
