On this day in history, April 29th 1429, Joan of Arc enters the besieged city of Orléans; the English siege of the city collapses only nine days later. The French repulsion of the besieging English at Orléans was the first major victory of the French in the Hundred Years' War since their crushing defeat at Agincourt almost fifteen years earlier. The Hundred Years' War, which lasted about 116 years, was fought between generations of succeeding English and French claimants to the French throne. The conflict began with the death of heirless French King Charles IV in 1328. English King Edward III was the Duke of Guyenne and Count of Ponthieu in France, and given his status in France and that he was Charles IV's nephew, Edward III considered himself a legitimate claimant. A French assembly chose a major French claimant as king, and while Edward seemed to acquiesce, when the new king began threatening Edward's holdings in France, war began.
