Career 
He was chairman of the Board of Finances in the Netherlands under Philip IV of Spain. He also commanded a royal regiment of Spanish troops, as well as travelling regularly to Holland to the States-General of the Netherlands. He was involved in the Conspiracy of Nobles (1632) and made efforts to convince France to invade the Southern Netherlands in support of a planned revolt against Spanish rule. Accused of abuse of his office before the plan came to fruition, he fled to Liège and issued a manifesto against the government in Brussels. Charged with high treason, he was sentenced to banishment and his property was confiscated. He soon sought reconciliation with the Spanish government. On 16 April 1637 he invited the anti-Spanish mayor of Liège, Sébastien de La Ruelle, to a banquet to be held in his house the next day. Once he had him as a guest in his house, he had him killed by hidden Spanish troops. Renesse was then lynched by an angry mob.
