Birth and family
Victoria's father was Prince Edward, Duke of Kent and Strathearn, the fourth son of the reigning King of the United Kingdom, George III. Until 1817, Edward's niece, Princess Charlotte of Wales, was the only legitimate grandchild of George III. Her death in 1817 precipitated a succession crisis that brought pressure on the Duke of Kent and his unmarried brothers to marry and have children. In 1818 he married Princess Victoria of Saxe-Coburg-Saalfeld, a widowed German princess with two children—Carl (1804–1856) and Feodora (1807–1872)—by her first marriage to the Prince of Leiningen. Her brother Leopold was Princess Charlotte's widower. The Duke and Duchess of Kent's only child, Victoria, was born at 4.15 a.m. on 24 May 1819 at Kensington Palace in London.
Victoria was christened privately by the Archbishop of Canterbury, Charles Manners-Sutton, on 24 June 1819 in the Cupola Room at Kensington Palace. She was baptised Alexandrina after one of her godparents, Emperor Alexander I of Russia, and Victoria, after her mother. Additional names proposed by her parents—Georgina (or Georgiana), Charlotte, and Augusta—were dropped on the instructions of Kent's eldest brother, George, the Prince Regent.
At birth, Victoria was fifth in the line of succession after the four eldest sons of George III: George, the Prince Regent (later George IV); Frederick, the Duke of York; William, the Duke of Clarence (later William IV); and Victoria's father, Edward, the Duke of Kent. The Prince Regent had no surviving children, and the Duke of York had no children; further, both were estranged from their wives, who were both past child-bearing age, so the two eldest brothers were unlikely to have any further children. The Duke of Clarence and the Duke of Kent married on the same day in 1818, but both of Clarence's daughters (born in 1819 and 1820) died as infants. Victoria's father died in January 1820, when Victoria was less than a year old. A week later her grandfather died and was succeeded by his eldest son, George IV. The Duke of York died in 1827. When George IV died in 1830, he was succeeded by his next surviving brother, William IV, and Victoria became heir presumptive. The Regency Act 1830 made special provision for the Duchess of Kent (Victoria's mother) to act as regent in case William died while Victoria was still a minor. King William distrusted the Duchess's capacity to be regent, and in 1836 he declared in her presence that he wanted to live until Victoria's 18th birthday, so that a regency could be avoided.
