The Victorian era is described as such because it refers to the period of time during Queen Victoria's reign over the United Kingdom. Queen Victoria ruled from June 20, 1837, until her death on January 22, 1901. The era is defined not only by her reign but also by the significant social, political, and cultural changes that occurred during this time.
