A year-long hostage crisis led to a presidency that would shape American politics for decades. But how much of what really happened is public?

Let’s imagine that Franklin D. Roosevelt had possessed the same gift for longevity as Jimmy Carter and lived until he was 100. He would have died in1982, in Ronald Reagan’s second year in office.

Jimmy Carter, the 39th President of the United States, will be eulogized at a state funeral Thursday at the National Cathedral and later by private family services and interment in Plains, Georgia.
