Five decades later, the assassination of John F. Kennedy remains one of the few utterly signal events from the second half of the 20th century. Other moments — some thrilling (the moon landing, the fall of the Berlin Wall), others horrifying (the killings of Martin Luther King Jr. and Robert Kennedy, the Challenger explosion) — have secured their places in the history books and, even more indelibly, in the memories of those who witnessed them. But nothing in the latter part of “the American century” defined an era as profoundly as those rifle shots that split the warm Dallas air on November 22, 1963, and the sudden death of the 46-year-old president.
Here, on the 45th anniversary of JFK’s March 1967 reinterment, when his remains were moved from his initial resting place to the permanent grave site and memorial at Arlington, LIFE.com offers a gallery of photographs (some of them never before published) from the deeply fraught funeral held mere days after Kennedy was killed.
While both ceremonies — the state funeral in ’63, and the reinterment three-and-a-half years later — were marked by sorrow, the rawness of the emotion evident in 1963 is still striking, and rending, today.
