Answer:
A. The Glorious Revolution
The Glorious Revolution is the name given to the Revolution of 1688, when King James II of England was overthrown. This was possible due to a union of English Parlamentarians with the Dutch stadholder William III, Prince of Orange. The revolution was partly motivated by King James's policies of religious tolerance, which highlighted the King's Catholicism and his ties to France.
B. Volatile
The seventeenth century was a period of relative volatility. During this period, the United Kingdom experienced many conflicts that altered the trajectory of their history. Some of these major events include the Union of the Crowns, the English Civil War, the Restoration, the Glorious Revolution and the Anglo-Dutch Wars.
