Ulster’s Solemn League and Covenant, commonly known as the Ulster Covenant, is signed by nearly 500,000 people on and before September 28, 1912, in protest against the Third Home Rule Bill introduced by the British Government in the same year.

The Covenant is first drafted by Thomas Sinclair, a prominent unionist and businessman from Belfast. Sir Edward Carson is the first person to sign the Covenant at Belfast City Hall with a silver pen, followed by Charles Stewart Vane-Tempest-Stewart, 6th Marquess of Londonderry (the former Lord Lieutenant of Ireland), representatives of the Protestant churches, and then by Sir James Craig. The signatories, 471,414 in all, are all against the establishment of a Home Rule parliament in Dublin. The Ulster Covenant is immortalised in Rudyard Kipling‘s poem “Ulster 1912.” On September 23, 1912, the Ulster Unionist Council votes in favour of a resolution pledging itself to the Covenant.

The Covenant has two basic parts: the Covenant itself, which is signed by men, and the Declaration, which is signed by women. In total, the Covenant is signed by 237,368 men; the Declaration, by 234,046 women. Both the Covenant and Declaration are held by the Public Record Office of Northern Ireland (PRONI). An online searchable database is available on the PRONI website.

In January 1913, the Ulster Volunteers aim to recruit 100,000 men between the ages of 17 and 65 who had signed the Covenant as a unionist militia. A British Covenant, similar to the Ulster Covenant in opposition to the Home Rule Bill, receives two million signatures in 1914.

The majority of the signatories of the Covenant are from Ulster, although the signing is also attended by several thousand southern unionists. Acknowledging this, Carson pays tribute to “my own fellow citizens from Dublin, from Wicklow, from Clare [and], yes, from Cork, rebel Cork, who are now holding the hand of Ulster,” to cheers from the crowd.

Robert James Stewart, a Presbyterian from Drum, County Monaghan, and the grandfather of Heather Humphreys, the Minister for Arts, Heritage and the Gaeltacht (2014-16) in the Republic of Ireland, is one of around 6,000 signatories in County Monaghan, where one quarter of the population is Protestant before the establishment of the Irish Free State. Almost 18,000 people sign either the Covenant or the Declaration in County Donegal.

The signature of Frederick Hugh Crawford is claimed by him to have been written in blood. However, this is disputed. Based on the results of a forensic test that he carries out in September 2012 at PRONI, Dr. Alastair Ruffell of Queen’s University Belfast asserts that he is 90% positive that the signature is not blood. Crawford’s signature is injected with a small amount of luminol. This substance reacts with iron in blood’s hemoglobin to produce a blue-white glow. The test is very sensitive and can detect tiny traces even in old samples. Crawford’s signature is still a rich red colour today which would be unlikely if it had been blood. Nevertheless, some unionists are not convinced by the evidence.

The term “Solemn League and Covenant” recalls a key historic document signed in 1643, by which the Scottish Covenanters make a political and military alliance with the leaders of the English Parliamentarians during the First English Civil War.

The Ulster Covenant is used as a template for the “Natal Covenant,” signed in 1955 by 33,000 British-descended Natalians against the nationalist South African government’s intention of declaring the Union a republic. It is signed in Durban‘s City Hall. Loosely based on Belfast’s Ulster Covenant, the Ulster scene is almost exactly reproduced.

September 28 is today known as “Ulster Day” to unionists.
