This was also the case most of the rest of the Low Countries.[24] Several sovereigns of the region, notably including Maria Theresa of Austria, succeeded in making French not only the language of the court but also of their administrations. For instance, while the major part of the population of Luxembourg speaks Luxembourgish in a private context, the administrative language of Luxembourg is French. As another example, the motto of the Kingdom of the Netherlands is the French phrase: "Je maintiendrai", because the language of the Orange-Nassau reigning family was French until 1890.
