De correspondentie van Willem van Oranje

This project aims to present a complete survey of all the surviving correspondence associated with William of Orange (1533-1584). The term 'correspondence' is used in the broadest sense and includes not only letters that were sent to or written by William of Orange, but also commissions, petitions, instructions and speeches. Research for this project was carried out in almost 200 archives and libraries in the Netherlands, Belgium, Denmark, Germany, England, France, Italy, Austria, Poland, Spain, Vatican City, Sweden and Switzerland--Project website.
