What charges led to Johan van Oldenbarnevelt’s death sentence?

Johan van Oldenbarnevelt was not condemned for high treason, despite public opinion being manipulated to believe so. Instead, he was sentenced to death for the "subversion" of the country’s religion and policy.1

Following his arrest by Prince Maurice in 1618, Oldenbarnevelt was tried by an extraordinary tribunal consisting of 24 judges, many of whom were his political and personal opponents. Despite his argument that he was a civil servant responsible only to the province of Holland, he was found guilty of these charges and was beheaded at the Binnenhof in The Hague in May 1619.1
