Glorious Revolution: Battle of the Boyne in Ireland (as reckoned under the Julian calendar).
The Battle of the Boyne (Irish: Cath na Binne IPA: [kah n bon]) was a battle in 1690 between the forces of the deposed King James II of England and Ireland, VII of Scotland, and those of King William III who, with his wife Queen Mary II (his cousin and James's daughter), had acceded to the Crowns of England and Scotland in 1689. The battle took place across the River Boyne close to the town of Drogheda in the Kingdom of Ireland, modern-day Republic of Ireland, and resulted in a victory for William. This turned the tide in James's failed attempt to regain the British crown and ultimately aided in ensuring the continued Protestant ascendancy in Ireland.
The battle took place on 1 July 1690 O.S. William's forces defeated James's army, which consisted mostly of raw recruits. Although the Williamite War in Ireland continued until the signing of the Treaty of Limerick in October 1691, James fled to France after the Boyne, never to return.
The Glorious Revolution of November 1688 (Irish: An Réabhlóid Ghlórmhar; Scottish Gaelic: Rèabhlaid Ghlòrmhor; Welsh: Chwyldro Gogoneddus), the invasion also known as the Glorieuze Overtocht or Glorious Crossing by the Dutch, was the deposition of James II and VII, king of England, Scotland and Ireland and replacement by his daughter Mary II and her husband, William III of Orange, stadtholder and de facto ruler of the Dutch Republic. A term first used by John Hampden in late 1689, historian Jeremy Black suggests it can be seen as both the last successful invasion of England and also an internal coup.Despite his Catholicism, James became king in February 1685 with widespread support as many feared his exclusion would lead to a repetition of the 1638–1651 Wars of the Three Kingdoms. Over the next three years, he alienated his supporters by suspending the Scottish and English Parliaments in 1685 and ruling by personal decree. Despite this, it was considered a short-term issue, as James was 52, and since his second marriage was childless after 11 years, the heir presumptive was his Protestant daughter Mary.
Two events in June 1688 turned dissent into a political crisis. The first was the birth of James Francis Edward on 10 June, displacing Mary as heir which created the prospect of a Catholic dynasty. The second was the prosecution of the Seven Bishops on 15 June; one in a series of perceived assaults on the Church of England, their acquittal on the 30th sparked anti-Catholic riots and destroyed James's political authority. The combination convinced a broad coalition of English politicians to issue an Invitation to William, inviting him to militarily intervene to protect the Protestant religion.
With Louis XIV of France preparing to attack the Dutch, William viewed this as an opportunity to secure English resources for the Nine Years' War, which began in September 1688. On 5 November, he landed in Brixham in Torbay with 14,000 men. As he advanced on London, most of the 30,000-strong Royal Army joined him. James went into exile on 23 December and in April 1689, Parliament made William and Mary joint monarchs of England and Ireland. A separate but similar Scottish settlement was made in June.
While the Revolution itself was quick and relatively bloodless, pro-Stuart revolts in Scotland and Ireland caused significant casualties. Although Jacobitism persisted into the late 18th century, the Revolution ended a century of political dispute by confirming the primacy of Parliament over the Crown, a principle established in the Bill of Rights 1689. The Toleration Act 1688 granted freedom of worship to nonconformist Protestants, but restrictions on Catholics contained in the 1678 and 1681 English and Scottish Test Acts remained in force until 1828; while religious prohibitions on the monarch's choice of spouse were removed in 2015, those applying to the monarch remain.
