prosecuted and their estates seized, with Charles replacing judges and sheriffs at will and packing juries to achieve conviction. To destroy opposition in London, Charles first disenfranchised many Whigs in the 1682 municipal elections, and in 1683 the London charter was forfeited. In retrospect, the use of the judicial system by Charles (and later his brother and heir James) as a tool against opposition, helped establish the idea of separation of powers between the judiciary and the Crown in Whig thought. Death Charles suffered a sudden apoplectic fit on the morning of 2 February 1685, and died aged 54 at 11:45 am, four days later, at the Palace of Whitehall. The suddenness of his illness and death led to suspicion of poison in the minds of many, including one of the royal doctors; however, a more modern medical analysis has held that the symptoms of his final illness are similar to those of uraemia (a clinical syndrome due to kidney dysfunction). Charles had a laboratory among his many interests, where prior to his illness he had been experimenting with mercury. Mercuric poisoning can produce irreversible kidney damage; but the case for this being a cause of his death is unproven. In the days between his collapse and his death, Charles endured a variety of torturous treatments including bloodletting, purging and cupping in hopes of effecting a recovery, which may have exacerbated his uraemia through dehydration instead of helping alleviate it. On his deathbed Charles asked his brother, James, to look after his mistresses: "be well to Portsmouth, and let not poor Nelly starve". He told his courtiers, "I am sorry, gentlemen, for being such a time a-dying", and expressed regret at his treatment of his wife. On the last evening of his life he was received into the Catholic Church in the presence of Father John Huddleston, though the extent to which he was fully conscious or committed, and with whom the idea originated, is unclear. He was buried in Westminster Abbey "without any manner of pomp" on 14 February. Charles was succeeded by his brother James II and VII. Legacy The escapades of Charles after his defeat at the Battle of Worcester remained important to him throughout his life. He delighted and bored listeners with tales of his escape for many years. Numerous accounts of his adventures were published, particularly in the immediate aftermath of the Restoration. Though not
