Question: Irish unionists use the two nations theory as a basis for opposing a movement that agitated for self-government that was the dominant political movement of Irish nationalism until when? 
Sentence (from "Taiwanese nationalism"): It is closely linked to Taiwan independence but distinguished from it in that the independence movement seeks to eventually establish an independent "Republic of Taiwan" in place of or out of the Republic of China and obtain United Nations and international recognition as a sovereign state (country), while the nationalism movement seeks only to establish or reinforce an independent Taiwanese identity that distinguishes Taiwan's people apart from Chinese nationalism, without necessarily advocating changing the official name of the Republic of China to "Republic of Taiwan".
Relevant evidence: No
