Queen Victoria was born in 1819 and became queen in 1837, less than a month after her eighteenth birthday. At over 63 years, she is the longest-reigning female monarch ever - anywhere in the world.
Of mostly German descent, Victoria continued the House of Hanover. She was a niece of her predecessor, King William IV. Victoria's first name was Alexandrina, after Emperor Alexander I of Russia (her godfather); Victoria was the name of her mother.
