A member of the Ernestine branch of the Wettin dynasty, he was the second son of Ernest, duke of Saxe-Coburg-Gotha. He was educated in Brussels and at the University of Bonn. The marriage between Victoria and Albert, who were first cousins, was promoted by their uncle Leopold I, king of Belgium. On Oct. 15, 1839, the young queen proposed to Albert, and they were married on Feb. 10, 1840.

Albert soon became, in effect, Victoria's private secretary and chief confidential adviser. Following his example, the Queen, who had been inclined to indolence, became almost as hardworking as he. At his urging she abandoned her Whig partisanship in favour of a more seemly political neutrality. Disputes with Prussia in 1856 and the United States in 1861 ended peacefully, at least in part because Albert suggested rewording Foreign Office dispatches so that they could not be construed as ultimatums.

Albert's vigilance was unwelcome to various government ministers, especially Lord Palmerston. The British aristocracy did not care for the severe moral tone of the royal household, for Albert's professorial manner (although he rode and shot as well as they), or for his artistic versatility. In collaboration with the London contractor Thomas Cubitt, Albert designed Osborne House (1845–51), the royal residence on the Isle of Wight. He was also an accomplished musician. He successfully managed the Great Exhibition of 1851 at the Crystal Palace, London, and was planning the South Kensington Exhibition of 1862 when he became fatally ill.
