He looked upon it as his patrimony.

His grandmother, Valentine Visconti, widow of that Duke of Orleans who had been assassinated at Paris in 1407 by order of John the Fearless, Duke of Burgundy, had been the last to inherit the duchy of Milan, which the Sforzas, in 1450, had seized.
When Charles VIII.

invaded Italy in 1494, "Now is the time," said Louis, "to enforce the rights of Valentine Visconti, my grandmother, to Milaness." And he, in fact, asserted them openly, and proclaimed his intention of vindicating them so soon as he found the moment propitious.
When he became king, his chance of success was great.

The Duke of Milan, Ludovic, the Moor, had by his sagacity and fertile mind, by his taste for arts and sciences and the intelligent patronage he bestowed upon them, by his ability in speaking, and by his facile character, obtained in Italy a position far beyond his real power.

Leonardo da Vinci, one of the most eminent amongst the noble geniuses of the age, lived on intimate terms with him; but Ludovic was, nevertheless, a turbulent rascal and a greedy tyrant, of whom those who did not profit by his vices or the enjoyments of his court were desirous of being relieved.
