William and Mary were crowned together at Westminster Abbey on 11 April 1689. The Archbishop of Canterbury usually performed coronations. But William Sancroft, the Archbishop at that time, felt that James II's removal had been wrong. Therefore, the Bishop of London, Henry Compton, crowned them instead. On the day of the Coronation, the Convention of the Estates of Scotland declared at last that James was no longer King of Scotland. William and Mary were offered the separate Scottish Crown. This was because the two kingdoms were not united until the Acts of Union in 1707. They accepted on 11 May.
