The first issue of the Northern Star, the newspaper of the Society of United Irishmen, is published in Belfast on January 4, 1792. It is published from 1792 until its suppression by the British army in May 1797.

The publication of an Irish newspaper that reflects and disseminates liberal views is an early goal of Irish republicans in the late 18th century. By the founding of the Society of United Irishmen in October 1791, the project is well underway, and the first edition of the Northern Star appears in Belfast in January 1792. Like the United Irishmen, the first financial backers of the Northern Star are Presbyterian and one of the United Irish leadership, Samuel Neilson, is made editor.

Political content dominates the Northern Star but its publication of local news, as opposed to the focus on British and international affairs of other Irish newspapers of the time, brings it wide popularity. Leading members of the United Irishmen are regular contributors and mixed direct political analyses with cutting political satire. William Orr is among those who contributed to its content and his letters lead to his eventual arrest and execution under the Insurrection Act of 1797. The newspaper also enjoys an excellent voluntary distribution network as its penetration follows rapidly wherever the United Irishmen set up new branches. It was estimated that for each copy of the Northern Star sold there are at least five readers, as the reading aloud of articles from the paper is a regular feature of United Irish meetings.

The newspaper is initially protected from the authorities due to the support of well-connected liberals but following the outbreak of war between Great Britain and Revolutionary France in 1793 and the subsequent banning of the United Irishmen as a seditious body it begins to draw increasing attention. The massive popularity of the newspaper protects it from serious harassment until January 1797 when the establishment goes into a state of panic following the French invasion scare at Bantry Bay. The paper is alleged to be behind the Dublin-based Union Star, a militant, low-circulation newssheet, often posted in public places, which specializes in naming informers, “notorious Orangemen,” and other enemies of the United Irishmen, being regarded by Dublin Castle as a republican hitlist.

The extensive distribution network and potency of the Northern Star in spreading United Irish opinion alarms the authorities and possession of a copy comes to be regarded as an admission of seditious intent. The end finally comes with the uncovering of supposed United Irish infiltration of the Monaghan militia in Belfast, which results in the execution of four soldiers. General Gerard Lake, 1st Viscount Lake, already engaged in a brutal counter-insurgency campaign, is quick to put much of the blame on the Northern Star and requests permission to suppress the paper.

As it turns out, official suppression is not necessary as on May 19, 1797, three days after the execution of their ex-comrades, a mob of Monaghan militiamen anxious to prove their loyalty attack the offices of the Northern Star and destroy not only the printing presses but the building itself. The attack results in the demise of the Northern Star to the undoubted satisfaction of the authorities as no action is taken against those involved in the destruction. The Chartist movement later pays tribute to the Northern Star by using the same name for their newspaper that is founded in 1837 by Feargus O’Connor.
