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.
Historically the politics of Scotland have reflected those of the UK as a whole, although with some differences. For example, besides the main UK-wide political parties (Labour, Conservatives and the Liberal Democrats) a number of Scottish-specific parties operate. These include the Scottish National Party (SNP), the Scottish Socialist Party (SSP) and the Scottish Green Party. These parties became more of a force in Scottish politics after the establishment of the Scottish Parliament in 1998.
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.
Scotland is one of the four constituent nations of the United Kingdom of Great Britain and Northern Ireland. The UK has no single written constitution document. Until the 1707 Acts of Union Scotland was an independent nation state. However, upon these acts coming into effect both Scotland and England's parliaments were dissolved and reconstituted as a parliament for all of Great Britain using the former English parliament's buildings and executive institutions. The Scottish and English crowns were unified in 1603 when James VI of Scotland became James I of England. In 1801 the Kingdom of Great Britain was unified with Ireland.
After World War II Scotland's economic situation became progressively worse until the 1970s, and only began to turn around after the discovery and development of North Sea oil and gas. During this period the Scottish National Party refocused their arguments for Scottish independence around their "It's Scotland's Oil" campaign.
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.
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.
From 1652 to 1658, Scotland formed an integral part of the Puritan-governed Commonwealth, under English control but gaining equal trading rights. Upon its collapse, nominal independence returned with the restoration of Charles II to the throne. Scotland regained its parliament, but the English Navigation Acts prevented the Scots from sharing its commercial success to escape impoverishment. A formal frontier between the two countries was re-established, with customs duties which, while they protected Scottish cloth industries from cheap English imports, also denied access to English markets for Scottish cattle on the hoof or Scottish linens (Braudel 1984 p 370).
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.
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.
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.
