The Ulster Volunteer Force (UVF) was established in January 1913, as a militant expression of Ulster Unionist opposition to the Third Home Rule Bill. Academic historians have tended to overlook Ulster Loyalism. This book provides the first comprehensive study of the UVF in this period considering in detail the composition of the officer corps, the marked regional recruiting differences, the ideologies involved, the arming and equipping of the UVF and the contingency plans made by UVF Headquarters in the event of Home Rule being imposed on Ulster.

Using previously neglected sources, it demonstrates that the UVF was better armed and worse trained, with the involvement of fewer British army officers than previous historians have allowed, and suggests that the UVF was quite capable of seizing control of Ulster and installing the Ulster Provisional Government in the event of Home Rule being implemented in 1914.
