The Victorian Period lasted from 1837 to 1901 under the reign of Queen Victoria. Some key events included Victoria becoming queen at age 18 in 1837 and marrying Prince Albert, with whom she had 9 children. Britain became the most powerful empire in the world during this time. Life for the rich and poor differed greatly, as the poor faced overcrowded cities with poor sanitation and child labor was common. Reforms to improve conditions gradually passed throughout Victoria's 64-year reign.
