What is older England or Scotland?

Answer 1

England became a unified state in 927. The equivalent point in time for Scotland is less clear. Tradition suggests the state was founded in 843 by Kenneth MacAlpin but in written history he is merely king of the Picts. The first king of Scotland/Scots was Donald II who ruled in 889. From this point of view Scotland is slightly older.

Edit: It wasn't until 1018 that the Angles were finally defeated in Scotland when Malcolm II defeated the English and Lothian became part of the country. This date of 1018 is also accepted as the formal foundation date for Scotland, making England nearly 100 years older than Scotland, so it depends if you want to take 843 or 1018 as the start date, both could be argued to be correct.

Answer 2

Scotland is older than England as a unified nation state. Scotland was established as a kingdom in the 9th century, while England was not unified until the 10th century.
