In 1543, when Wolfgang reached majority and took on the responsibilities of office, he enacted the Marburg Contract, giving his uncle Rupert, who had served as his regent and guardian for 11 years, the County of Veldenz.

This was the joining of the House of Wittelsbach with the Swedish Vasa royal family which was strengthened by a further marriage when Johann Casimir of Pfalz-Zweibrücken married Catharina of Sweden, a sister of Gustavus Adolphus in the 17th century.

Wolfgang had in 1553 with the Heidelberg Succession agreement regulated the mutual inheritance of all Wittelsbach lines reaching from Veldenz-Palatinate to the county Lützelstein in Alsace.

The grandson of Georg Hans, Leopold Ludwig von Lützelstein, died in 1694 as a poor man without legitimate offspring and the county-Palatinate of Veldenz, which was in ruins after many French attacks, reverted to the Zweibrücken line, specifically King of Sweden Charles XI, who ruled in personal union with the duchy of Palatine Zweibrücken.

When the personal union of Sweden and Zweibrücken ended and following agreements among the Wittelsbach family, Veldenz went to the bordering Electoral Palatinate in 1733.
