George I (George Louis; German: Georg Ludwig; 28 May 1660 – 11 June 1727) was King of Great Britain and Ireland from 1 August 1714 and ruler of the Electorate of Hanover within the Holy Roman Empire from 23 January 1698 until his death in 1727. He was the first British monarch of the House of Hanover.
Born in Hanover to Ernest Augustus and Sophia of Hanover, George inherited the titles and lands of the Duchy of Brunswick-Lüneburg from his father and uncles. In 1682, he married his cousin Sophia Dorothea of Celle, with whom he had two children; he also had three daughters with his mistress Melusine von der Schulenburg. George and Sophia Dorothea divorced in 1694. A succession of European wars expanded George's German domains during his lifetime; he was ratified as prince-elector of Hanover in 1708.
As the senior Protestant descendant of his great-grandfather James VI and I, George inherited the British throne following the deaths in 1714 of his mother, Sophia, and his second cousin Anne, Queen of Great Britain. During his reign the powers of the monarchy diminished, and Britain began a transition to the modern system of cabinet government led by a prime minister. Jacobites attempted, but failed, to depose George and replace him with James Francis Edward Stuart, Anne's Catholic half-brother. Towards the end of his reign, actual political power was held by Robert Walpole, now recognised as Britain's first de facto prime minister.
George died in 1727 on a journey to his native Hanover, where he was buried. He is the most recent British monarch to be buried outside Britain. He was succeeded by his son, George II.
George was born on 28 May 1660 in the city of Hanover in the Duchy of Brunswick-Lüneburg in the Holy Roman Empire. He was the eldest son of Ernest Augustus, Duke of Brunswick-Lüneburg, and his wife, Sophia of the Palatinate. Sophia was the granddaughter of King James I of England, through her mother, Elizabeth Stuart, Queen of Bohemia.
For the first year of his life George was the only heir to the German territories of his father and three childless uncles. George's brother, Frederick Augustus, was born in 1661, and the two boys (known respectively by the family as "Görgen" and "Gustchen") were brought up together. In 1662 the family moved to Osnabrück when Ernest Augustus was appointed ruler of the Prince-Bishopric of Osnabrück, while his older brother George William ruled in Hanover. They lived at Iburg Castle outside the city until 1673 when they moved to the newly completed Schloss Osnabrück. The parents were absent for almost a year (1664–1665) during a long convalescent holiday in Italy but Sophia corresponded regularly with her sons' governess and took a great interest in their upbringing, even more so upon her return. Sophia and Ernest Augustus had another four sons and a daughter. In her letters, Sophia describes George as a responsible, conscientious child who set an example to his younger brothers and sisters.
By 1675, George's eldest uncle had died without issue, but his remaining two uncles had married, putting George's inheritance in jeopardy, for his uncles' estates might pass to their own sons, were they to have any, instead of to George. George's father took him hunting and riding and introduced him to military matters; mindful of his uncertain future, Ernest Augustus took the fifteen-year-old George on campaign in the Franco-Dutch War, with the deliberate purpose of testing and training his son in battle.
In 1679 another uncle died unexpectedly without sons, and Ernest Augustus became reigning Duke of Calenberg-Göttingen, with his capital at Hanover. George's surviving uncle, George William of Celle, had married his mistress in order to legitimise his only daughter, Sophia Dorothea, but looked unlikely to have any further children. Under Salic law, inheritance of territory was restricted to the male line, so the succession of George and his brothers to the territories of their father and uncle now seemed secure. In 1682 the family agreed to adopt the principle of primogeniture, meaning George would inherit all the territory and not have to share it with his brothers.
In 1682, George married Sophia Dorothea of Celle, the daughter of his uncle George William, thereby securing additional incomes that would have been outside Salic laws. This marriage of state was arranged primarily to ensure a healthy annual income, and assisted the eventual unification of Hanover and Celle. His mother at first opposed the marriage, because she looked down on Sophia Dorothea's mother, Eleonore (who came from the lower French nobility), and because she was concerned by Sophia Dorothea's legitimated status. She was eventually won over by the advantages inherent in the marriage.
In 1683, George and his brother Frederick Augustus served in the Great Turkish War at the Battle of Vienna, and Sophia Dorothea bore George a son, George Augustus. The following year, Frederick Augustus was informed of the adoption of primogeniture, meaning he would no longer receive part of his father's territory, as he had until then expected. This led to a breach between Frederick Augustus and his father, and between the brothers, that lasted until his death in battle in 1690. With the imminent formation of a single Hanoverian state, and the Hanoverians' continuing contributions to the Empire's wars, Ernest Augustus was made a prince-elector of the Holy Roman Empire in 1692, pending confirmation by the Imperial Diet. George's prospects were now better than ever as the sole heir to his father's electorate and his uncle's duchy.
Sophia Dorothea had a second child, a daughter named after her, in 1687, but there were no other pregnancies. The couple became estranged—George preferred the company of his mistress, Melusine von der Schulenburg, and Sophia Dorothea had her own romance, with the Swedish Count Philip Christoph von Königsmarck. Threatened with the scandal of an elopement, the Hanoverian court, including George's brothers and mother, urged the lovers to desist, but to no avail. According to diplomatic sources from Hanover's enemies, in July 1694, the Swedish count was killed, possibly with George's connivance, and his body thrown into the river Leine weighted with stones. The murder was claimed to have been committed by four of Ernest Augustus's courtiers, one of whom, Don Nicolò Montalbano, was paid the enormous sum of 150,000 thalers, about one hundred times the annual salary of the highest-paid minister. Later rumours supposed that Königsmarck was hacked to pieces and buried beneath the Hanover palace floorboards. However, sources in Hanover itself, including Sophia, denied any knowledge of Königsmarck's whereabouts.
George's marriage to Sophia Dorothea was dissolved, not on the grounds that either of them had committed adultery, but on the grounds that Sophia Dorothea had abandoned her husband. With her father's agreement, George had Sophia Dorothea imprisoned in Ahlden House in her native Celle, where she stayed until she died more than thirty years later. She was denied access to her children and father, forbidden to remarry and only allowed to walk unaccompanied within the mansion courtyard. She was, however, endowed with an income, establishment, and servants, granted access to her mother and allowed to ride in a carriage outside her castle under supervision. Melusine von der Schulenburg acted as George's hostess openly from 1698 until his death, and they had three daughters together, born in 1692, 1693 and 1701.
Ernest Augustus died on 23 January 1698, leaving all of his territories to George with the exception of the Prince-Bishopric of Osnabrück, an office he had held since 1661. George thus became Duke of Brunswick-Lüneburg (also known as Hanover, after its capital) as well as Archbannerbearer and a prince-elector of the Holy Roman Empire. His court in Hanover was graced by many cultural icons such as the mathematician and philosopher Gottfried Leibniz and the composers George Frideric Händel and Agostino Steffani.
