text: Genoa was important in the politics of 12th-century Europe. The Genoese were a nation of merchants, and such was their wealth that they frequently fulfilled a role as bankers to the other nation states. However, the Genoese became divided following the rift caused when the Emperor Frederick II challenged the power of Pope Innocent IV. Two distinct camps formed: the Guelphs who supported the pope and the Ghibellines who were loyal to the imperial crown. Siding with the Guelphs were one of the patrician families of Genoa—the Grimaldi. Throughout the 13th century these two groups fought. Finally at the end of the century the Ghibellines were victorious and banished their opponents, including the Grimaldi, from Genoa. The Grimaldi settled in the area today known as the French Riviera. Several castles in the area are still known as Chateau Grimaldi, and testify to the strong presence of various branches of the family in the vicinity.
  Legend relates that in January 1297 François Grimaldi, disguised as a monk, sought shelter at the castle. On obtaining entry he murdered the guard, whereupon his men appeared and captured the castle. Thus the fortress became the stronghold of the Grimaldi. This event is commemorated by a statue of François Grimaldi in the precincts of the palace (Illustration 6) and in the arms of the House of Grimaldi where François is depicted wielding a sword while in the garb of a monk (Illustration 2).
