OK, here's a few snippets from a web page about Ireland:
1609: The Plantation of Ulster
By the end of Queen Elizabeth 1's reign, military conquest had established English rule over most of the island of Ireland, with the principal exception of the northern province of Ulster. The Ulster clans, under Hugh O'Neill, had succeeded in overcoming their instinctive rivalries to create an effective alliance against Elizabeth's armies. After a long and damaging campaign, Ulster was eventually brought under English control and the Irish leaders left the island for Europe. Their land was confiscated and distributed to colonists from Britain. By 1703, less than 5 per cent of the land of Ulster was still in the hands of the Catholic Irish.
The Plantation of Ulster was unique among Irish plantations in that it set out to attract colonists of all classes from England, Scotland and Wales by generous offers of land. Essentially it sought to transplant a society to Ireland. The native Irish remained, but were initially excluded from the towns built by the Planters, and banished to the mountains and bogs on the margins of the land they had previously owned. The sum of the Plantation of Ulster was the introduction of a foreign community, which spoke a different language, represented an alien culture and way of life, including a new type of land tenure and management. In addition, most of the newcomers were Protestant by religion, while the native Irish were Catholic. So the broad outlines of the current conflict in Northern Ireland had been sketched out within fifty years of the plantation: the same territory was occupied by two hostile groups, one believing the land had been usurped and the other believing that their tenure was constantly under threat of rebellion. They often lived in separate quarters. They identified their differences as religious and cultural as well as territorial.
The next two centuries consolidated the differences. There were many risings. The Dublin based institutions of government - an Irish monarchy, parliament and government, reflecting those in Britain enforced a series of penal laws against Catholics and, to a lesser extent, Presbyterians. In 1801, in an attempt to secure more direct control of Irish affairs, the Irish parliament and government were abolished by an Act of Union and its responsibilities taken over by Westminster. During the nineteenth century a succession of movements attempted to overthrow the union. Some of these movements, including the Repeal movement in the 1840s and the Home Rule movement from the 1870s, were parliamentary. Others, like the Fenians and the Irish Republican Brotherhood, were dedicated to overthrowing the union by the use of physical force. It is probable that the union would have been repealed by a Home Rule act but for the intervention of the First World War. During the war an armed rising was attempted in Dublin during Easter week, 1916. The rising failed and the leaders were executed, creating a wave of sympathy for the IRA and its political wing, Sinn Féin. In the 1918 election Sinn Féin effectively replaced the old Irish Parliamentary Party and established its own Irish parliament. The resulting War of Independence between Britain and the IRA was eventually ended by a treaty and the Government of Ireland Act in 1920.
Since the 1880s, many Ulster Protestants had become increasingly concerned about the possible establishment of home rule for Ireland. They prepared for resistance. In 1912 a civil war seemed imminent, but the focus was shifted from Ulster by the start of the First World War and by the Easter rising. From 1918, Ulster Protestants increasingly settled for a fall-back position and set out to ensure that the northern counties of Ireland, at least, should be excluded from any Home Rule arrangements. The 1920 Government of Ireland Act, which came into effect in the following year, recognised and confirmed their position by partitioning the island.
1921: Partition
The 1921 settlement precipitated a civil war in the southern 26 counties, between those willing to accept the settlement and those who believed it was a betrayal. Northern Ireland, the name given to the new six county administration, had been created through demographic compromise. It was essentially the largest area which could be comfortably held with a majority in favour of the union with Britain. The new arrangements established a bicameral legislature, and a subordinate government in Belfast with authority over a number of devolved powers, including policing, education, local government and social services. London retained ultimate authority, and Northern Ireland sent MPs to Westminster.
The establishment of these institutions was a challenge to what some Irish republicans saw as unfinished business. The objective of securing a united independent Ireland, by force if necessary, remained, and there were IRA campaigns in the 1920s, 1940s and 1950s. For many unionists the new arrangements and the union itself could only be maintained with constant vigilance. Emergency legislation was introduced on a permanent basis; a police force and police reserve was established which was almost exclusively Protestant; local government electoral boundaries were openly gerrymandered, a stratagem also used by nationalists when they were able to do so; and a system of economic discrimination was introduced against the Catholic minority in Northern Ireland. This minority formed about one third of the population for most of the twentieth century, and currently represents around 40 per cent.
A number of Westminster-led social changes after the Second World War, including the introduction of free secondary education for all, led during the 1950s to the emergence of a Catholic middle class. It was their growing dissatisfaction that led to the civil rights campaign of the 1960s.
Civil Rights and After: 1969
By the 1950s there were growing signs that some Catholics were prepared to accept equality within Northern Ireland rather than espouse the more traditional aim of securing a united Ireland. In 1967 the Northern Ireland Civil Rights Association was formed to demand liberal reforms, including the removal of discrimination in the allocation of jobs and houses, permanent emergency legislation and electoral abuses. The campaign was modelled on the civil rights campaign in the United States, involving protests, marches, sit-ins and the use of the media to publicise minority grievances. The local administration was unable to handle the growing civil disorder, and in 1969 the British government sent in troops to enforce order. Initially welcomed by the Catholic population, they soon provided stimulus for the revival of the republican movement. The newly formed Provisional IRA began a campaign of violence against the army. By 1972 it was clear that the local Northern Irish government, having introduced internment in 1971 as a last attempt to impose control, was unable to handle the situation. Invoking its powers under the Government of Ireland Act, the Westminster parliament suspended the Northern Ireland government and replaced it with direct rule from Westminster. This situation continued into the 1990s.
On paper the civil rights campaign had been a remarkable success. Several of its objectives had been conceded by the end of 1970. By that time, however, proceedings had developed their own momentum. The IRA campaign developed strongly from 1972. Instead of the riots between Catholics and Protestants which had characterised 1969 and 1970, the conflict increasingly took the form of violence between the Provisional IRA and the British Army, with occasional bloody interventions by loyalist paramilitaries. The violence reached a peak in 1972, when 468 people died. Since then it has gradually declined to an annual average of below 100.
Themes
Since the twelfth century therefore, it is possible to discern significant shifts in the Irish problem. Until 1921, it was essentially an Irish-English problem and focused on Ireland's attempt to secure independence from Britain. From 1921 the emphasis shifted to relationships within the island of Ireland, between what later became the Republic of Ireland and Northern Ireland; this issue has somewhat revived since the signing of the Anglo-Irish agreement in 1985. Finally, since 1969, attention has focused on relationships between Catholics and Protestants within Northern Ireland.
2. THE MAIN PARTIES
Unionists
Unionists are the successors of those who opposed Home Rule in the nineteenth century, and eventually settled for the state of Northern Ireland. The main unionist parties are the Ulster Unionist Party (OUP), which formed all governments from 1921 to 1972; and the more recently established Democratic Unionist Party (DUP), which is more populist, more anti-nationalist, but less popular in electoral support. Both are opposed to the involvement of the Irish Republic in Northern Ireland, and are unwilling to share executive power with non-Unionist parties. They also share a suspicion of Britain's commitment to the union. The DUP holds all these positions more extremely than the UUP, and also is more preoccupied with the power of the Catholic church. In 1994 the leader of the UUP was James Molyneaux, and Ian Paisley led the DUP.
Nationalists
The basic tenet of nationalists is the aspiration to unify the island of Ireland. The main constitutional party is the Social Democratic and Labour Party (SDLP), which contests the nationalist vote with Sinn Féin, generally accepted to be the political arm of the IRA. The SDLP campaigns for internal reforms, and has accepted that unity must await the support of the majority in Northern Ireland. Sinn Féin argues that force is necessary to remove the British presence, and that its mandate is historical. Sinn Féin has refused to condemn the IRA, and has not been included in any official political talks. John Hume led the SDLP in 1994, and Gerry Adams Sinn Féin.
The Paramilitary Organisations
The republican paramilitary organisations, of which the IRA is by far the most important, believe that only force will remove the British from Ireland. Initially they saw themselves as defenders of the Northern Catholic minority, but later spread their military activities throughout Northern Ireland, Britain and Europe. There is disagreement about whether loyalist violence is essentially reactive, but certainly the pattern of loyalist violence has shadowed republican violence. There has been a major shift in the form of violence since 1990, with loyalists for the first time killing more victims than republicans. It has been speculated that this rise in loyalist violence may be connected to the failure of recent political talks.
The United Kingdom
The official British position is that Northern Ireland is part of the United Kingdom. This is shared by all parties, although the Labour Party favours Irish unity, when the majority in Northern Ireland support it. Until 1993 most political talks have aimed to restore a devolved government, with power shared between unionists and nationalists. The 1985 Anglo-lrish Agreement between the British and Irish governments accepted that the Dublin government had the right to be consulted on Northern Irish affairs.
Hope that helps!
