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.

Funeral services for former President Jimmy Carter began Saturday as the U.S. pays respect to the 39th president who passed away last Sunday at 100 years old. The nation will honor Carter over six days of funeral events.
