After the 22 January 1798, coup d'état by general
Herman Willem Daendels, he was appointed
agent for finance and foreign affairs (
pro tem) under the new . However, the contraventions of the new, democratic, constitution of 1798 by the
Pieter Vreede regime disaffected him, and he conspired with the other agents and again general Daendels to overthrow that regime in June 1798. He then became a member of the himself for a short while, till elections had been held for a new Representative Assembly. He was again appointed Agent, this time for Finance, by the new . He now started on the reform of the Dutch system of public finance that was long overdue. He attempted to reorganize the tax system, but because this entailed abolition of the old, federal arrangements, he met strong resistance. He tried to attain three main objectives with his imposing General Tax Plan: construction of a system of regularly levied taxes, instead of the hodge-podge of
ad hoc taxes and forced loans that the Republic had to rely on to make ends meet; a shift away from regressive, indirect taxes toward direct income taxes; and an equalization of the tax burden between different parts of the country. Besides, he proposed to form a new, national organisation to collect the taxes. His General-Taxation-Plan legislation was first proposed in 1799, but only enacted on 15 March 1801.
Nationale Konst-Gallery '', the first of many works that Roos purchased and resold to Gogel Modelled after the
Louvre, Gogel envisioned a National art gallery for art-lovers and artists alike, that would promote the country's art heritage and educate its citizens. Starting in 1798, he started to create the
Nationale Konst-Gallery (now
Rijksmuseum). His motivation was partially developed out of the worries shared by many art lovers in the Netherlands at that time that the
French saviors of freedom would take more than just one collection with them to Paris, as in 1795 the entire contents of Willem V's gallery had been installed in the Louvre. He decided on a place and two major types of art, and these were the
Huis ten Bosch location with its magnificent
Oranjezaal and the concepts "historieele" and "moderne" art. Gogel saw that under the new government, he was able to appropriate pieces from distributed Royal collections (such as the Oranjezaal itself) and felt that if he did this in a systematic way with the intention to found a national collection, he would thus "save" the art from the French "saviors". For his national inventory in 1799 he appointed an inspector for this job:
Cornelis Sebille Roos. As a patriot, Gogel was mostly interested in what he saw as "patriotic" art that promoted the country and taught a moral lesson, which indicates that probably it was Roos who put the moralistic text on
The Threatened Swan" in order to sell the painting to Gogel. == Grand Pensionary Schimmelpenninck (1805-1806) ==
