for the construction of the RMS Titanic. Sectarian divisions in Ulster became hardened into the political categories of unionist (supporters of the Union with Britain; mostly, but not exclusively, Protestant) and nationalist (advocates of repeal of the 1800 Act of Union, usually, though not exclusively, Roman Catholic). Northern Ireland's current politics originate from these late 19th century disputes over Home Rule that would have devolved some powers of government to Ireland, and which Ulster Protestants usually opposed—fearing for their religious rights calling it "Rome Rule" in an autonomous Roman Catholic-dominated Ireland and also not trusting politicians from the agrarian south and west to support the more industrial economy of Ulster. This lack of trust, however, was largely unfounded as during the 19th and early 20th century important industries in the southernmost region of Cork included brewing, distilling, wool and like Belfast, shipbuilding. Thousands of unionists, led by the Dublin-born barrister Sir Edward Carson and James Craig, signed the "Ulster Covenant" of 1912 pledging to resist Home Rule. This movement also set up the Ulster Volunteer Force (UVF). In April 1914, the UVF assisted with the landing of 30,000 German rifles with 3,000,000 rounds at Larne by blockading authorities. (See Larne gunrunning). The Curragh Incident showed it would be difficult to use the British army to enforce home rule from Dublin on Ulster's unionist minority. In response, Irish republicans created the Irish Volunteers, part of which became the forerunner of the Irish Republican Army (IRA) – to seek to ensure the passing of the Home Rule Bill. Upon the outbreak of World War I in 1914, 200,000 Irishmen, both Southern and Northern, of all religious sects volunteered to serve in the British Army. This had the effect of interrupting the armed stand-off in Ireland. As the war progressed, in Ireland, opposition to the War grew stronger, reaching its peak in 1918 when the British government proposed laws to extend conscription to all able bodied Irishmen during the Conscription Crisis. In the aftermath of World War I, the political party Sinn Féin ("Ourselves") won the majority of votes in the 1918 Irish general election, this political party pursued a policy of complete independent self-determination for the island of Ireland as outlined in the Sinn Féin campaign Manifesto of 1918, a great deal more than the devolved government/Home Rule advocated by the (I.P.P) Irish Parliamentary Party. Following the Sinn Féin victory in these
