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.
At one stage, Scottish peers were entitled to elect sixteen representative peers to the House of Lords. In 1963, the Peerage Act was passed, allowing every Scottish peer to sit in the House of Lords. However, since the current Labour government's reforms of that house this is no longer the case and hereditary Scottish peers have to stand for election from amongst all eligible peers to sit in the house as part of a group of 92 entitled to do so.
Much of Scotland (particularly the West Central Belt around Glasgow) has experienced problems owing to the religious divide between Presbyterians and Catholics. Many Scottish Catholics maintain that, because many Establishment and business figures have links to the Orange Order, sectarianism is deeply rooted in Scottish society. This problem has historically manifested itself in a number of ways, particularly in employment and in football fanaticism. The problems associated with sectarianism in Scotland have diminished markedly compared with the past, although issues do remain to a certain degree. Scottish police have recently moved to restrict the number of Orange parades.
In 1547, after the death of Henry VIII, forces under the English regent Thomas Somerset were victorious at the battle of Pinkie Cleugh, the climax of the Rough Wooing and followed up by occupying Edinburgh. However it was to no avail since Queen Mary was in France and Marie de Guise called on French reinforcements who helped stiffen resistance to the English occupation. By 1550, after a change of regent in England, the English withdrew from Scotland completely.
Before 1975 local government in Scotland was organised on the county system. In reforms that took effect from 1975, the Conservative government of Edward Heath introduced a system of two-tier local government in Scotland, divided between large Regional Councils and smaller District Councils. The only exceptions to this were the three Island Councils, Western Isles, Shetland and Orkney which had the combined powers of Regions and Districts. In 1995 the Conservative government of John Major decided to abolish this system and merge their powers into new Unitary Authorities, roughly equivalent to the old counties.
Most Scottish industry and commerce is concentrated in a few large cities on the waterways of the central lowlands. Edinburgh, on the Firth of Forth, is a cultural centre, the capital of Scotland, and one of the the top financial centres in Europe. Glasgow, one of the largest cities in the UK, lies on the Clyde; it is Scotland's leading seaport and was once a centre of shipbuilding and it supports numerous light industries. Although heavy industry has declined, the high-technology Silicon Glen corridor has developed between Glasgow and Edinburgh. Tourism is also very important.
Islam is the largest non-Christian religion in Scotland, although its numbers remain very small.
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.
