The Edwardian Era spans the rule of King Edward the VII.

Explanation:

The Edwardian Era describes in British cultural history the time from the accession of Edward VII in 1901 to the outbreak of World War I in 1914. Historically, the Edwardian Era is an echo of the Victorian Age. The British Empire was at its peak during this period, but at the same time it signaled that Britain's time as the world's leading nation was soon over.

In the Edwardian era, the British class system was very strict. However, economic and social change created an environment where this was changing. There was an increased interest in socialism, a focus on the condition of the poor and women, including women's suffrage, and greater economic opportunities due to industrialization. These changes went faster after World War I.
