In the 1870s, using the Dual Monarchy of Austria–Hungary as a model, the Prince of Wales (later King Edward VII) and William Ewart Gladstone proposed that Ireland and Great Britain form a dual monarchy.
1870. aastatel, kasutades Austria-Ungari kaksikmonarhiat mudelina, kavandasid Walesi prints (hilisem kuningas Edward VII) ja William Ewart Gladstone, et Iirimaa ja Suurbritannia moodustavad kaksikmonarhia.
