Prince Albert of Saxe-Coburg and Gotha (Francis Albert Augustus Charles Emmanuel, later HRH The Prince Consort; 26 August 1819 – 14 December 1861) was the husband of Queen Victoria of the United Kingdom of Great Britain and Ireland.

He was born in the Saxon duchy of Saxe-Coburg-Saalfeld to a family connected to many of Europe's ruling monarchs. At the age of 20 he married his first cousin, Queen Victoria, with whom he had nine children. At first, Albert felt constrained by his position as consort, which did not confer any power or duties upon him. Over time he adopted many public causes, such as the abolition of slavery and educational reform, and took on the responsibilities of running the Queen's household, estates and office.
