When, in 1715, the fear of a general Jacobite rising induced the Whigs to take serious precautions, Hyde Park became a camp from July till November. During a similar scare in 1722 troops were again quartered there, and the camp became the centre of popular attraction; gaiety and frivolity were the order of the day, rather than business or watchfulness. The Park was also used as a camp for six regiments of militia at the time of the Gordon Riots in 1780. All through George III.'s long reign reviews were frequent, and one of the most popular was that held by the Prince Regent before the allied sovereigns, the Emperor of Russia and King of Prussia, in June 1814. Blucher was the popular hero on the occasion, and when he afterwards appeared in the Park he was so mobbed by the crowd, enthusiastic to see something of "Forwarts," as he was familiarly named, that he had to defend himself against their rough treatment.
