Fulk IV, known as Fulk le Réchin, was born in the year one thousand forty-three and became the Count of Anjou around one thousand sixty-eight. His reign lasted until his death on the fourteenth of April in one thousand one hundred nine. Fulk was a figure of considerable notoriety, often described as a man with many reprehensible and scandalous habits.
Orderic Vitalis, a contemporary chronicler, took particular note of Fulk's lifestyle, which included numerous romantic entanglements. This aspect of his character contributed to his controversial reputation, as he was often criticized for his indulgences and the company he kept.
In addition to his personal life, Fulk IV is remembered for his influence on fashion, particularly through his promotion of the pigaches, a style of footwear that eventually evolved into the poulaine, a long-toed shoe popular in medieval Europe. His impact on both society and culture during his time remains a point of interest for historians.
