century used the following sets of arms. On becoming prince of Orange, William placed the Châlon-Arlay arms in the center ("as an inescutcheon") of his father's arms. He used these arms until 1582 when he purchased the marquisate of Veere and Vlissingen. It had been the property of Philip II since 1567, but had fallen into arrears to the province. In 1580 the Court of Holland ordered it sold. William bought it as it gave him two more votes in the States of Zeeland. He owned the government of the two towns, and so could appoint their magistrates. He already had one as First Noble for Philip William, who had inherited Maartensdijk. This made William the predominant member of the States of Zeeland. It was a smaller version of the countship of Zeeland (& Holland) promised to William, and was a potent political base for his descendants. William then added the shield of Veere and Buren to his arms as shown in the arms of Frederick Henry, William II and William III with the arms of the marquisate in the top center, and the arms of the county of Buren in the bottom center. William also started the tradition of keeping the number of billets in the upper left quarter for Nassau at 17 to symbolize the original 17 provinces of the Burgundian/Habsburg Netherlands, which he always hoped would form one united nation. When John William Friso became Prince of Orange, he used the arms below. However, he was never recognized outside of Holland and areas friendly to Holland as Prince of Orange. His son, William IV, recognized as Prince of Orange, seems to have used the original arms of William the Silent. When the princes of Orange fled the Netherlands during the Batavian Republic and the Kingdom of Holland, and when France occupied the Netherlands, they were compensated by Napoleon with the Principality of Nassau-Orange-Fulda. These principalities were confiscated when Napoleon invaded Germany (1806) and William VI supported his Prussian relatives. He succeeded his father as prince of Orange later that year, after William V's death. The house of Orange-Nassau also had several illegitimate lines (see below) who based their arms on the arms of Nassau-Dillenburg. When William VI of Orange returned to the Netherlands in 1813 and was proclaimed Sovereign Prince of the Netherlands, he quartered the former Arms of the Dutch Republic (1st and 4th quarter) with
