The Ulster Workers Council Strike began #OnThisDay, the 15th of May 1974.
It had been called by unionists and loyalists in opposition to the Sunningdale power sharing agreement. Continuing until the 28th of May, it resulted in the collapse of the short-lived Northern Ireland Assembly formed under that agreement.
