Some historical facts about Scotland
After the Norman Conquest in 1066 many English noblemen from Inglis (old form of the term English) fled to the North of Great Britain. The Scottish king supported their settlement, but the political border between Scotland and England caused Inglis to diverge from the southern speech. The settlers in Scotland, then, spoke the Northumbrian dialect, which was more based on the speech of the Angles, and the continental legal system was adopted by them. Through time, Scotland built up a language of its own which was noch understandable to the people south of the border.
In 1605 the Scottish king James VI succeeded Queen Elizabeth I of England and became King James I of England. He ruled the Kingdom of England, Scotland and Ireland, and James' court moved from Edinburgh to London. He began to use more Southern English in his writings and under his rule the flourishing of English literature continued. The former official language grew to be the summarizing notion for a number of different and only-spoken dialects. Even today there are some words and pronunciations left of ancient times, when there still was the Kingdom of Scotland.
Along the centuries of the English rule a new standard arose. The union between England and Scotland was just a personal one, but in 1707 it became a real union. Scotland preserved its legal system and certain words for this system. In addition, the country has kept some unique words in their standard speech. The language contact between Scots and Standard English of England after the 17th century created the now known Scottish English.
