The decision to establish a republic in 1919, rather than any other form of government, was significant because it amounted to a complete repudiation of all constitutional ties with Great Britain, and set the party against any compromise that might involve initial self-government under the Home Rule Act 1914 or continued membership of the British Empire.
A decisión de establecer unha república en 1919, no canto de calquera outra forma de goberno, foi significativa porque respondía a un total repudio de toda relación constitucional coa Gran Bretaña, e puña ao partido contra calquera compromiso que puidese prexudicar o autogoberno inicial ou a continua pertenza ao Imperio Británico.
