William Drennan was an Irish physician, political writer, and poet who played a pivotal role in the late eighteenth-century Irish reform movement. Born in Belfast, Drennan trained as a physician but became deeply involved in the political turbulence of his era. He was an active participant in the Irish Volunteer movement and achieved early renown for his passionate public addresses. Writing to his "fellow slaves" and directly to the British Viceroy, Drennan consistently urged for full and final Catholic emancipation and the establishment of a more representative government.\n\nDrennan is most famous for instigating the formation of the Society of United Irishmen in both Belfast and Dublin. He authored the Society's original "test," a solemn declaration that committed Irishmen of all religious persuasions to a "brotherhood of affection" in pursuit of democratic reform. Although he distanced himself from the radical violence that culminated in the 1798 Rebellion, Drennan remained committed to his ideals. Following the suppression of the uprising, he continued to advocate for democratic reform through his active journalism and educational initiatives.\n\nIn his later years, Drennan co-founded the Belfast Academical Institution (which later became the Royal Belfast Academical Institution) to promote non-sectarian education. As a literary figure, he is widely remembered for his 1795 poem "When Erin First Rose," which famously coined the enduring description of Ireland as the "Emerald Isle."
