King Robert I of Naples a.k.a. Robert the Wise, son of King Charles II of Naples the Lame, was Duke of Calabria (1296-1309), King of Naples and (nominal) Jerusalem and Sicily, and Count of Provence and Forcalquier (1309-1343).

He was made King of Naples and Sicily in 1309, his reign being blessed by Rome’s 196th Pope Clement V (born Bertrand de Got in Gascony, France). King Robert I was nicknamed "the peace-maker of Italy" due to the years of significant changes he made to Naples. Tradesmen from Italy and abroad erected superb buildings, monuments and statues that drastically changed King Robert's capital from a dirty seaport to a city of elegance and medieval splendor.

Head of the Guelph army at Genoa, King Robert reigned until his death in 1343 under Rome’s 199th Pope Clement VI. He was succeeded by his young granddaughter, Jeanne d'Anjou or Joan I of Naples.
