Instruction of 12 April 1588
In the history of the Netherlands, the instruction of 12 April 1588 (Dutch: instructie van 12 april 1588) is a decision of the States General of the Netherlands (also known as the "Generality") passed on 12 April 1588 during the Eighty Years' War. It transferred the duties of the executive branch of government from the landvoogd (from which Robert Dudley, 1st Earl of Leicester had recently resigned) to the Council of State. In conjunction with a separate decision taken by the States General to transfer the oaths of allegiance of all officials from Leicester to themselves on the same day, the instruction is widely regarded as the formal establishment of the Dutch Republic.
