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.
Church of England broke with Catholicism primarily for political reasons. Thus they replaced very little traditional Catholic theology, except to substitute the Crown for the Pope as the head of the Church. The Scots on the other hand were primarily Presbyterian, a movement which was the result of a strong theological rejection of certain Catholic teachings. In particular they were sceptical of the authority of the Pope and priesthood generally, which they rejected in favour of the priesthood of all believers. This doctrine was seen by both sides as radically undermining the authority not just of the priestly class, but of the aristocracy since it was essentially democratic.
This state of affairs continued until May 1999 when Scotland's Parliament was established following a referendum. Whereas the old Scottish Parliament had functioned as the full parliament of a sovereign state, the new parliament governs the country only on domestic matters, the United Kingdom Parliament having retained responsibility for Scotland's defence, international relations and certain other areas.
In 1468 the last great acquisition of Scottish territory occurred when James III married Margaret of Denmark, receiving the Orkney Islands and the Shetland Islands in payment of her dowry.
The largest political party operating in Scotland is the Labour Party. They replaced the Liberals as Scotland's main political force in the early twentieth century and traditionally represent the interests of workers and trade-unionists. They currently operate as the senior partners in a coalition Scottish Executive.
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.
During the 16th century, Scotland became embroiled in the throes of the Protestant Reformation. John Knox stood out as the primary figure in this battle. A disciple of John Calvin, Knox, waged fierce battles with the forces of Catholic orthodoxy and eventually converted the country to Presbyterianism. Only the most distant parts of the Highlands retained a taste for older forms. Presbyterianism first gained a foothold in 1556 but it didn't really get going until John Knox's firebrand oratory started stirring people up, most notably in Perth, when he roused the townsfolk so much that a mob scoured the countryside for Catholics after one of his sermons, destroying the old abbey at Scone in the process. Within a few years Parliament had legislated for a National Presbyterian church, the Catholic Queen had fled, Scotland had Protestant England rather than Catholic France as its main ally, and firm Presbyterian tutors were in charge of the upbringing of the infant King.
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.
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.
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.
