England (pronounced IPA: /ˈɪŋglənd/) is a country in the north west of Europe and constituent country of the United Kingdom. England has an estimated population of 50,714,000, thus making it the most densely populated constituent country, accounting for more than 83% of the total UK population. It occupies most of the southern two-thirds of the island of Great Britain and shares land borders with Scotland to the north and with Wales to the west. During the 10th century, England became a unified state, taking its name from the Angles, one of several Germanic peoples who settled in the territory.
England ranks among one of the world's most far-reaching and influential centres of cultural development across the world. Since the Act of Union in 1707, England has not had a government or constitution. It was under this act, that the Kingdom of England and the Kingdom of Scotland became united, and formed the Kingdom of Great Britain, commonly referred to today as The United Kingdom.
The establishment of the Church of England occurred during the English Reformation in the 16th Century, when the authority of the Roman Catholic Church was abolished and replaced by Royal Supremacy. The English reformation differed significantly from the other countries of Europe, as England's was political, rather than theological like other European countries. The flag of England is the cross of St. George, who is also England's patron saint and St George's Day, which falls on England's national day.
