Claim: In 1294, Louis I, who created a court and a mint, which minted coins for the lords of Vaud between 1286 and 1350, began to expand Arzier (a municipality in Nyon District, located some 25 kilometers north east of Geneva's city centre) as a center of his power, but in 1359 however, Nyon lost importance after Amadeus VI acquired rights over the entire Vaud.
Evidence: In 1294, Louis I began to expand Nyon as a center of his power after Amadeus granted his share of the conquest to Louis.
