English culture is unique in itself. While some aspects of the culture have withstood centuries some have died of and have little influence now.
One clearly evident part of their culture is the monarchical form of government that rules over the people.
Another aspect of their culture that is unique to them is that their form of english has been from the accumulation of many different languages through invasions and wars. This form of english doesn't differ far from american english except for slang words as seen in their meal 'fish and chips' which is fish and french fries in America.
Other than government and slang, England's culture doesn't change much from America's culture.
