Francesco, however, was evicted only a few years after by the Genoese forces, and the struggle over "the Rock" continued for another century. The Grimaldi family was Genoese and the struggle was something of a family feud. However, the Genoese became engaged in other conflicts, and in the late 1300s Genoa lost Monaco in conflict with the Crown of Aragon over Corsica. Aragon eventually became part of a united Spain, and other parts of the land grant came to be integrated piecemeal into other states.
