The Victorian Era was known as the period where Queen Victoria ruled England. It lasted 68 years, as Queen Victoria assumed the role in 1837 until 1901. It is the longest reign that a British monarch has had.
This period was known for having a hierarchy based social order. As Queen Victoria wanted to regain some of the lost respect the public had towards the Kingdom, society started to benefit those with "noble titles", which were granted by the Queen to a selected number of individuals. This produced a pronounced form of classism an among British society, as middle-class citizens often lost their jobs to people with a certain relation to those who had honorific titles. It was an era of high expectations, as people often were prejudices towards others due to their background.
