Discrimination against Catholics and nonconformists, attempts by the British administration to suppress Irish culture, and the belief that Ireland was economically disadvantaged as a result of the Act of Union were among the specific factors leading to such opposition.
Diskriminácia katolíkov, pokusy britskej správy potlačiť írsku kultúru a viera, že Írsko bolo ekonomicky znevýhodnené v dôsledku Dohody o únií z roku 1800 boli hlavné faktory, vedúce k takejto opozícií.
