1st clarify the question ....
By 'settled' is it queried when was it first 'populated' ie settled with people? If so the answer is 'forever', because the oldest surviving artifacts are coincident with end of the last Ice Age, but are sufficiently substantial and socially developed that they must have been preceded by ancient primitive settlements and populations of which no traces survived.
In terms of the traceable ancestors of the current scottish population, we are the descendants of 5 'species' - the 4 nations Angles, Britons, Picts and Scots, plus the Norsemen (Vikings) who controlled the Northern and Western Isles into the 12th centuryAD. The Angles generally occupied the southeast, the Britons the southwest, both with territorial spread across the current political border. The Picts were the inhabitants of the mountainous highland area from the retreat of the ice and the Scots invaded from Ireland.
Myth is that the Scots originated in the Black Sea and were displaced into their boats to survive where they could settle. This is rather romantically (but unsubstantiated) documented in the Declaration of Arbroath, the famous and beautifully written request to the Pope of the day in 1320 to respect the sovereignty of Scotland established by battle in 1314, and requesting the Pope to instruct the English king to desist from attempting to invade the Scots. If only.
No-one knows for certain when the first settlers arrived in what is now Scotland. But certainly 3000 years before Christ simple flint users arrived from what is now Ireland, England and Norway. However, there may have been people settled in Scotland before that. The first King of Scotland was Kenneth McAlpin in 843. This is long after the Romans left.
ireland was firt settled 8,000 years ago
Grimsby is a town and Scotland is a country - it will depend on which part of Scotland you are travelling to. Your question is like asking how far from New York to Canada.
It is unknown when exactly the first humans settled in Mali. The first kingdom in Mali that we know of was established around 700-800 A.D.
Scotland was not founded by England, as they are two separate countries with their own histories and origins. Scotland has been a distinct political entity since the Middle Ages, with a history that dates back to the Kingdom of Scotland in the 9th century. England and Scotland eventually formed the United Kingdom in 1707 through the Act of Union.
There were really no established 'countries' in the area that long ago, but the area today would be eastern Mexico.
you would actually have to fly about 3 hours.
First, Spanish explorers landed at Winyah Bay in 1521. They started a settlement in 1526. French settled near present-day Beaufort in 1562. But, Neither of them didn't last long and died from disease and hunger. Later, English settlers found Charles Towne in 1670 and settled there. They were the first permanent European settlement.
The pioneers settled a long time ago.
Kenneth Macalpin (Kenneth I) became the first recognised King of Scotland in 843 (although the name Scotland had no meaning then) and ruled till 860. The Scotti tribe of North Ireland settled on the west coast of Scotland in the 6th century and called their new kingdom Dalriada. Kenneth became King of Dalriada in 840. He was the first to be both King of Dalriada and King of the Picts (the indigenous population of Scotland at that time) through marriage to the daughter of a Pictish Chief and to sire an heir to the throne. There were Kings of both Dalriada and Pictland before Kenneth but none could hold on to it long enough to produce an heir thus starting a new lineage.
The first people to live in Scotland were likely Celtic tribes. However, Scotland has a long history of occupation by various peoples, including Picts, Romans, and Vikings. As for showing a map, I recommend checking a reliable online map source such as Google Maps or the National Library of Scotland website for an up-to-date map of Scotland.
Scotland is bigger than Wales.
