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.
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.
Until 1832 Scottish politics remained very much in the control of landowners in the country, and of small cliques of merchants in the burghs. However by 1885 around 50% of the male population had the vote, the secret ballot had become established, and the modern political era had started.
In 1512 under a treaty extending the Auld Alliance, all nationals of Scotland and France also became nationals of each other's countries, a status not repealed in France until 1903 and which may never have been repealed in Scotland. However a year later, the Auld Alliance had more disastrous effects when James IV was required to launch an invasion of England to support the French when they were attacked by the English under Henry VIII. The invasion was stopped decisively at the battle of Flodden Field during which the King, many of his nobles, and over 10,000 troops — The Flowers of the Forest — were killed. The extent of the disaster impacted throughout Scotland because of the large numbers killed, and once again Scotland's government lay in the hands of regents.
The modern system of branch banking (in which banks maintain a nationwide system of offices rather than one or two central offices) originated in Scotland. Only strong political pressure during the 19th century prevented the resultant strong banking system from taking over banking in England. However, although Scottish banks proved unwelcome in England at the time, their business model became widely copied, firstly in England and later in the rest of the world.
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.
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.
