On the arrival of Amadeus in Spain, Ruiz Zorilla became minister of public works for a short time, and resigned by way of protesting against Serrano and Topete entering the councils of the new king.
He passed the Reynolds range and Lake Amadeus in that direction, but was compelled to turn south, where he found a tract of well-watered grassy land.
When Amadeus succeeded to the throne these were divided into the county of Savoy (his own territory), the princi pality of Piedmont ruled by his nephew Philip, prince of Achaea (a title acquired through his wife, Isabella of Villehardouin, heiress of Achaea and the Morea), and Vaud ruled by his brother Louis.
But although this division was formally recognized in 1295, Amadeus succeeded in enforcing his own supremacy over the whole country and making of it a more unified state than before, and by war, purchase or treaty he regained other fiefs which his predecessors had lost.
Five years later the council of Basel by a strange decision elected Amadeus pope, in spite of his not being a priest, and deposed Eugenius IV.
