The old county militia in Scotland was not re-established at the Restoration of 1660. After the Union in 1707, during the War of the Spanish Succession, the Parliament of Great Britain passed an Act in 1708 to re-arm the Scottish Militia. However, the Act was denied Royal assent because of fears that the new force would be disloyal (a Jacobite uprising in Scotland was expected to support the French invasion fleet that was then at sea). During the serious Jacobite rising of 1745, the government-supporting Major-General John Campbell of Mamore (later 4th Duke of Argyll) raised the irregular Campbell of Argyll Militia, which was present at the Battle of Falkirk Muir, the Skirmish of Keith, and the Battle of Culloden.
