* The Ulster Volunteers started in 1912 and organised as the Ulster Volunteer Force in 1913

The potential success of the third Home Rule Bill in 1912 introduced serious tensions: opponents of the Bill organised the Ulster Volunteer Force in January 1913 while supporters formed the Irish Volunteers in response.

In his first public speech as leader at the Royal Albert Hall on 26 January 1912 he listed his three biggest concerns: an attack on the Liberal government, for failing to submit their ideas for Home Rule to a referendum ; tariff reform ; and the Conservative refusal to let the Ulster Unionists be " trampled upon " by an unfair Home Rule bill.

On 28 September 1912, Carson led 237, 638 of his followers in signing a Solemn League and Covenant saying that Ulster would refuse to recognise the authority of any Parliament of Ireland arising from Home Rule.

In 1912, following the entry of the Third Home Rule Bill through the House of Commons, unionists organised mass resistance to its implementation, organising around the " Ulster Covenant ".

In 1912 they formed the Ulster Volunteers, an armed wing of both Ulster Unionism and the Orange Order who stated that they would resist Home Rule by force.

It was ostensibly formed in response to the formation of the Ulster Volunteers in 1912, and its declared primary aim was " to secure and maintain the rights and liberties common to the whole people of Ireland ".

It would be the third Home Rule Bill, introduced in 1912, which would lead to the crisis in Ireland between the majority Nationalist population and the Unionists in Ulster.

On 28 September 1912 at Belfast City Hall just over 450, 000 Unionists signed the Ulster Covenant to resist the granting of Home Rule.

Following the establishment of the Ulster Volunteers in 1912, whose purpose was to resist Home Rule, by force if necessary, the IRB were behind the initiative which eventually led to the inauguration of the Irish Volunteers in November, 1913.

The envisaged threat from both Home Rule and Rome was expressed in an angry poem by Rudyard Kipling Ulster 1912 ’’ 4th verse:

An Ulster Covenant was also made in 1912, opposing the idea of Home Rule in Ireland.

The Ulster Volunteers were a unionist militia founded in 1912 to block Home Rule for Ireland.

He was soon a prominent leader of the Unionist wing of the Conservative Party, especially in the planned Ulster resistance to Irish Home Rule in 1912 – 14, during which time he was known as ' Galloper Smith '.

Unionists had objected to inclusion to potential rule by the proposed Dublin Parliament and had founded the Ulster Volunteers paramilitary group in 1912 to fight if necessary against the British government and / or against a future Irish Home Rule government proposed by the Bill.

He was the first Democrat elected from his district to represent Ulster County since 1912.

In 1912 he signed the Ulster Covenant.

By 1912 Protestant influence remained strong in Ulster, based not on farmland but on new industries that had been developed after 1800.

All the arguments for and against Home Rule, in general or as proposed in the Bill, were made by both sides from the day it was introduced in April 1912 The main issue of contention during the parliamentary debates was the " coercion of Ulster ", and mention was made of whether or which counties of Ulster should be excluded from the provisions of Home Rule.

On ‘ Ulster Day ’ 28 September 1912 over five hundred thousand Unionists signed the Ulster Covenant pledging to defy Home Rule by all means possible, drawn up by Irish Unionist leader Sir Edward Carson and organised by Sir James Craig, who in January 1911 had spoken of a feeling in Ulster that Germany and the German Emperor would be preferred to the ‘ rule of John Redmond, Patrick Ford ( veteran Fenian ) and the Molly Maguires '.
