President Jimmy Carter died on Dec. 29 at the age of 100, leaving behind a decades-long legacy in politics, humanitarian work, and global peace negotiations.

Despite only serving a single term in the White House from 1977 to 1981, Carter’s life is one of diverse achievement, from his time in the Navy while studying nuclear physics to his years as a peanut farmer, to his rapid rise from Georgia politics to becoming the top executive in the United States.
