Scotland also has its own unique family of languages and dialects, helping to foster a strong sense of "Scottish-ness". An organisation called Iomairt Cholm Cille has been set up to support Gaelic-speaking communities in both Scotland and Ireland and to promote links between them.
The significance of coal, once Scotland's most important mineral resource, has declined. Oil, however, gained prominence in Scotland's economy during the 1970s, with the growth of North Sea oil extraction companies. Natural gas is also abundant in the North Sea fields. Aberdeen is the centre of the oil industry. Other important industries are textile production (woollens, worsteds, silks, and linens), distilling, and fishing. Textiles, beer, and whisky, which are among Scotland's chief exports, are produced in many towns. Salmon are taken from the Tay and the Dee, and numerous coastal towns and villages are supported by fishing from the North Sea. Only about one quarter of the land is under cultivation (principally in cereals and vegetables), but sheep raising is important in the mountainous regions.
The Scottish National Party (SNP) was formed in the 1930s with the aim of achieving Scottish independence. They are broadly on the left-of-centre and are in the European Social-Democratic mould. They are currently the second most popular party electorally, although their highpoint appears to have been in the 1970s.
The election of the Labour government in 1997 ensured that there would be a referendum on establishing a devolved Scottish Parliament. This was held in September, 1997 and the Scottish people voted 75% in favour of its establishment.
The Parliament is elected with a Proportional Representation electoral system, namely, the Additional Members System. This is unlike Westminster which is still elected by the First Past the Post method. It is elected every four years and contains 129 members (referred to as MSPs).
Scotland retains its own unique legal system, based on Roman law, which combines features of both civil law and common law. The terms of union with England specified the retention of separate systems. The barristers being called advocates, and the judges of the high court for civil cases are also the judges for the high court for criminal cases. Scots Law differs from England's common law system.
In 1326, the first full Scottish Parliament met. The parliament had evolved from an earlier council of nobility and clergy, the colloquium, constituted around 1235, but in 1326 representatives of the burghs — the burgh commissioners — joined them to form the Three Estates.
Scotland's territorial extent is generally that established by the 1237 Treaty of York between Scotland and England and the 1266 Treaty of Perth between Scotland and Norway. Exceptions include the Isle of Mann, which is now a crown dependency outside the United Kingdom, Orkney and Shetland, which are Scottish rather than Danish, and Berwick-upon-Tweed, which was defined as subject to the laws of England by the 1746 Wales and Berwick Act.
A number of other Christian denominations exist in Scotland, amongst them Roman Catholicism, which made a comeback through immigration from Ireland, after Protestants brutally repressed it during the 16th to late 18th centuries. It has now become the largest faith after The Kirk. As well as The Kirk we find various other Protestant churches, including the Scottish Episcopal Church, which forms a full part of the Anglican Communion, and the Free Church of Scotland, a Presbyterian off-shoot from the established Church of Scotland.
In 1603, the Scottish King James VI inherited the throne of England, and became James I of England. James moved to London and only returned to Scotland once. In 1707, the Scottish and English Parliaments signed the Treaty of Union, which was deeply unpopular in Scotland, as it had been negotiating from a position of economic weakness and suffering from English tariffs. Implementing the treaty involved dissolving both the English and the Scottish Parliaments, and transferring all their powers to a new Parliament sitting in London which then became the Parliament of the United Kingdom. A customs and monetary union also took place.
Scotland has its own BBC services which include the national radio stations, BBC Radio Scotland and Scottish Gaelic language service, BBC Radio nan Gaidheal. There are also a number of BBC and independent local radio stations throughout the country. In addition to radio, BBC Scotland also runs two national television stations. Much of the output of BBC Scotland Television, such as news and current affairs programmes, and the Glasgow-based soap opera, River City, are intended for broadcast within Scotland, whilst others, such as drama and comedy programmes, aim at audiences throughout the UK and further afield. Sports coverage also differs, reflecting the fact that the country has its own football leagues, separate from those of England.
Humans have lived in Scotland since the end of the last glaciation, around 10,000 years ago. Of the stone, bronze, and iron age civilisations which occupied the country, many artefacts, but few examples of writing, remain. Thus the written History of Scotland largely begins with the arrival of the Roman Empire in Britain. From a classical historical viewpoint Scotland seemed a peripheral country, slow to gain advances filtering out from the Mediterranean fount of civilisation, but as knowledge of the past increases it seems remarkable how early and advanced some developments have been, and how important the seaways were to Scottish history. The country's lengthy struggle with England, its more powerful neighbour to the south, repeatedly forced it to rely on trade, cultural and often strategic ties with a number of European powers. Following the Act of Union and the subsequent Scottish Enlightenment and Industrial Revolution, Scotland became one of the commercial, intellectual and industrial powerhouses of Europe. Its industrial decline following World War II was particularly acute, but in recent decades the country has enjoyed something of a cultural and economic renaissance, fuelled in part by a resurgent financial services sector, the proceeds of North Sea oil and gas, and latterly a devolved parliament.
Scotland, in the geographical sense it has retained for nearly a millennium, completed its expansion by the gradual subsumation of the Britons' kingdom of Strathclyde into Alba. In 1034, Duncan I, descended from Irish Ui Neill monastery protectors and appointed to the crown of Strathclyde some years earlier, inherited Alba from his maternal grandfather, Malcolm II. With the exception of Orkney, the Western Isles, Caithness and Sutherland, which had come under the sway of the Norse, Scotland stood unified.
