Attempts had been made in the 1920s to create a youth movement linked to that of the Conservative Party (the Junior Imperial and Constitutional League) without much success.

The UYUC was formed by the Standing Committee of the Ulster Unionist Council in 1946 and quickly became a successful movement in South & West Belfast, Fermanagh and Down.

The body re-emerged under the Chairmanship of David McNarry and continued to thrive throughout the 1980s, producing figures such as Edgar Graham, Jeffrey Donaldson, Peter Weir and Arlene Foster with the latter 3 defecting to the DUP.

In recent years the Young Unionists have continued to function as an active political youth wing.

The Young Unionists host a number of events on an annual basis including a summer debate series, conference and social events as well as canvassing for elected reps. Up to 15 Honorary positions are available; Second UYUC Current Young Unionists
