The Jacobite rebellion of 1715 was a dramatic but ultimately unsuccessful challenge to the new Hanoverian regime in Great Britain. It did, however, reveal serious fault lines in the political foundations of the new regime which enormously restricted the government’s freedom of action in the suppression of the rebellion, and effectively made the treatment of the rebels in its aftermath the true test of the new dynasty’s legitimacy and stability. Whilst the rulers of England had traditionally dealt harshly with internal rebellion, monarchs and their ministers had to find a delicate balance between showing the power of the regime through the candid exercise of force while maintaining their own reputation for justice and clemency. As such George I and his government had to tailor their reaction to the 1715 rebellion in such a way that it effectively discouraged further participation in Jacobite insurgency, undercut the rebels’ ability to challenge the state, and made clear the regime’s intention to use a firm hand in preventing rebellion. At the same time it could not cross the line into tyranny with excessive or sadistic executions and had to avoid giving offence to powerful magnates and foreign powers likely to petition for the lives of the captured rebels. To accomplish this feat, the Hanoverian Whig regime used a programme far more subtle and calculated than has generally been appreciated. The scheme it put into effect had three components, to put fear into the rank-and-file of the rebels through a limited programme of execution and transportation, to cripple the Catholic community through imprisonment and property confiscation, and, most crucially, to entertain petitions from members of the elite on behalf of imprisoned rebels. By following such a strategy of retribution tempered with clemency, this book argues that the Hanoverian regime was able to quell the immediate dangers posed by the rebellion, and bring its leaders back into the orbit of the government, beginning the process of reintegrating them back into political mainstream.
