Antoine I de Croÿ

In 1452, he secured for himself the post of Governor General of the Netherlands and Luxembourg,[2] and presided over the pro-French party at the court of Philip the Good, Duke of Burgundy.

While on a mission to the court of King Charles VII of France, he was implicated in the assassination of Louis of Valois, Duke of Orléans, and as a consequence, suffered torture in the Château de Blois.

In 1437, he married his daughter Jeanne to Louis I, Count Palatine of Zweibrücken, in order to increase his influence in the orbit of the Holy Roman Empire.

In 1455, he proceeded with the building of the Kasteel van Arenberg on the site of a demolished medieval castle, of which he had destroyed all but one tower; the château would not be completed until 1515, by his grandson, William de Croÿ.

With Charles the Bold, the future Duke of Burgundy, he was at loggerheads, especially after they had clashed over the inheritance of Jeanne d'Harcourt, Countess of Namur.
