Acte van Consulentschap
The Acte van Consulentschap (; in English historiography variously known as Act of Advisership, or less correctly, as Act of Consultation) was a secret, private contract between stadtholder William V, Prince of Orange of the Dutch Republic and his mentor and former guardian Duke Louis Ernest of Brunswick-Lüneburg, concluded on 3 May 1766 (shortly after William's majority), in which the latter was informally given continued powers of guardianship over the stadtholder in his private and public capacity. Not only gave this document the Duke a nefarious influence over affairs of state in the Republic, but when  it became public in 1784 it caused such a scandal that the stadtholder's regime was almost fatally undermined in the political upheaval of the Patriottentijd. Background. When William V's father William IV, Prince of Orange died in 1751, the young prince was only three years of age. His mother Anne, Princess Royal and Princess of Orange became Regent for her son in as far as the hereditary office of stadtholder was concerned. Before his death, however, William IV had already made arrangements to give the Duke a role as her adviser. In any case, the ancillary office of  Captain-General of the Dutch States Army could not be exercised by a woman, and the Duke was appointed its Captain-General. The Duke remained in this position during the subsequent regencies of Landgravine Marie Louise of Hesse-Kassel and Princess Carolina of Orange-Nassau. During this entire period he had great influence on the prince's education, and an almost father-son relationship developed between the two. The Act and its influence. In the eyes of contemporaries the young prince had not fully matured before he reached his majority on 8 March 1766, and became stadtholder in his own  right. The class of ruling "Regenten" therefore felt anxious about his taking the reins of power unchecked, and the pensionary of Delft, Pieter van Bleiswijk, a leading member of the States of Holland and the States General of the Netherlands for Holland, together with other grandees, like the Grand Pensionary Pieter Steyn took the initiative of making an arrangement in which "for the time being" the influence of the Duke would be informally continued. This was formalized in a contract (which later became known as the "Acte van Consulentschap" or Act of Advisorship), drawn up by van Bleiswijk, and concluded  between the Prince and the Duke on 3 May 1766. Both signed it, and the Duke swore to it, according to the witness, the Princes' secretary, F.J. de Larrey The Act consisted of our articles. All of this until further notice from either party. The Act remained secret for a long time, but of course the inner circle around the Prince knew about it. If necessary, the Duke would brandish it, if challenged by other courtiers, like Willem Bentinck van Rhoon. The immediate effect of the Act was that an attempt to saddle the stadtholder with an "advisory council" was  thwarted. As will be clear from the above account of the contents of the Act, it did not give the Duke formal powers over the stadtholder, but it helped him exploit the natural ascendancy he had enjoyed over William from an early age. The relationship helped to perpetuate the dependence of the younger on the older person to an "unhealthy" extent, as was recognized by many in their environment. The Duke was instrumental in obtaining the hand in marriage of Wilhelmina of Prussia, Princess of Orange, a niece of the Prussian king Frederick the Great, whom William married on 4  October 1767, but the Princess soon started to resent the Duke's influence, and she became one of his main opponents. The Duke had many other enemies, who blamed him for many of the mistakes the Prince made. The conduct of the Fourth Anglo-Dutch War was seen as one of his main failures, and in other military respects, like the encroachments of the new emperor of Austria, Joseph II, in the Austrian Netherlands. This caused the dismissal of the Duke as Captain-General on 24 May 1782, though he remained governor of the fortress of 's-Hertogenbosch until the  crisis of the Kettle War in 1784. Because of this removal the Act was no longer operational, and in any case the Duke no longer was a convenient lightning rod for the political opposition from the Patriots, who from then on more and more attacked the stadtholder himself. When in the issues of 19, 23, 26, and 30 June 1784 of the De Post van den Neder-Rhijn, a Patriot newspaper, its editor Pieter 't Hoen published the previously secret text of the Act, a tremendous scandal broke out in the Republic, which made the position of the Duke untenable , and severely harmed the political position of the stadtholder. The fact that it was a private contract that never gave due deference to the position of the true sovereign of the country, the States General, drew 't Hoen's stentorian criticism. It proved in his eyes that the Duke (and by extension the Prince) from the beginning of William's stadtholderate had denied the true constitutional relationships within the Republic, and arrogated a "monarchical" position for the Prince, which was contrary to what that position in the eyes of the Patriots ought to be. The scandal gave his opponents the  opportunity to engineer the Duke's definitive removal. Princess Wilhelmina demanded his dismissal. The States of Holland on 18 August 1784 declared the Act null and void. In the States General they proposed his dismissal as field marshal of the States Army, a rank he still held after his dismissal as Captain-General in 1782, and his deportation from the country. The States of Friesland already had demanded this on 11 June. The Duke resigned his commission on 14 October 1784, and left the Republic for Aachen.
