The Battle of Reading was a consequential confrontation during the Glorious Revolution, which unfolded in December 1688. The conflict began as William of Orange, who had earlier invaded England, sought to rally support against the Catholic King James II. The Williamite forces, composed mainly of Protestants, confronted the royalist Jacobites loyal to James II in the town of Reading. Despite the numerical disadvantages, the Williamite troops executed strategic maneuvers that led to a decisive victory against the Jacobite forces. As the battle culminated, it became clear that the support for James II was dwindling, prompting him to retreat and ultimately flee England in search of safety. This retreat illustrated the waning power of a king who was increasingly isolated due to his faith and unpopular policies.

The battle not only showcased the shifting tides of loyalty among English subjects but also revealed the precarious position of James II's reign. The outcome solidified William of Orange's position as the new leader in England and set the stage for significant political changes. Following this confrontation, the English Parliament would convene to offer the throne to William and his wife Mary, solidifying the transition from absolute to constitutional monarchy in England.
