One hundred years ago, in 1914, society was very different than it is today. Britain had a huge divide between the rich and the poor, far more so than there is today, where we have a large "middle class".
In 1914 most people were either working or upper class, known as the aristocracy.
This is illustrated well in the ITV drama "Downton Abbey", whose first season takes place between 1912 and 1914, and clearly illustrates this class divide, giving insight into to the aristocratic Crawley family and their array of servants including valets, footmen, cooks, chauffers and ladies maids.
The first world war began in 1914, which seemed to pull the nation together and put some perspective on the extravagant lives of the upper class. So much so that- both during and after the war- things began to change, and the upper class, slowly, become more in touch with their working class counterparts.
