What is the Ulster Covenant?

The Ulster Covenant is a pledge made by almost half a million people from Northern Ireland on September 28, 1912, 'Ulster day'.

Those that signed the Covenant promised to reject Home Rule in Ireland and to remain within the United Kingdom. Here is an extract:

We, whose names are underwritten, men of Ulster, loyal subjects of His Gracious Majesty King George V, humbly relying on the God whom our fathers in days of stress and trial confidently trusted, do hereby pledge ourselves in solemn Covenant, throughout this our time of threatened calamity, to stand by one another in defending for ourselves and our children our cherished position of equal citizenship in the United Kingdom and in using all means which may be found necessary to defeat the present conspiracy to set up a Home Rule parliament in Dublin.
