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.
The traditional political divides of left and right have also intersected with arguments over devolution, which all the UK-wide parties have supported to some degree throughout their history (although both Labour and the Conservatives have swithered a number of times between supporting and opposing it). However, now that devolution has occurred, the main argument about Scotland's constitutional status remains between those who support Scottish independence and those who oppose it. Recent trends indicate, according to the State of the Nation Poll 2004, that 66% of Scots would like the Scottish Parliament to have more powers, while only 2% would like to see the powers returned to Westminster.
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.
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.
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.
Scotland was historically represented in the UK government by the Secretary of State for Scotland. This post was established in the 1880s but recently it has been the topic of much speculation. Many believe that since devolution there is no need for such a role to exist. The current Secretary of State is Alastair Darling.
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.
Tied as it was to the health of the British Empire, Scotland suffered after the First World War as it had gained beforehand. In the Highlands, which, for cultural reasons, had provided a disproportionate number of recruits for the British army, a whole generation of young men were lost, and many villages and communities suffered greatly. In the Lowlands, particularly Glasgow, the terrible working and living conditions for the industrial workers, many of whom did not agree with the motives of the war, led to industrial and political unrest. John MacLean became a key political figure in Red Clydeside and on Bloody Friday January 31st 1919, the British Government was so fearful of a revolutionary uprising in Glasgow that tanks and soldiers were stationed in George Square.
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.
