1364:

Charles V crowned King of France

Charles was known as "the Wise" for his scholarship. He also led France in recovery from the devastation of the first part of the Hundred Years' War.

1455:

Calixtus III elected pope

Alfonso Borgia was 77 years old when he became Pope Calixtus III. His diplomacy and influence -- along with that of Tommasso Parentucelli (later Pope Nicholas V, whom he succeeded) -- had helped heal a schism in the church. During his short reign as Pope, Calixtus worked in vain for a crusade to save Christendom from the Turks. He also ordered the re-examination of Joan of Arc's case. His most notable flaw was nepotism, showering favors on his nephew, the notorious Rodrigo Borgia, and making him a cardinal.
