I note that there were several othe Bloody Sundays in other places. The Irish cannot maintain a monopoly on such events. There are two separate issues involved: disambiguating agent and format. The latter I raise because of your being new. Had the disambiguator been otherwise been propertly chosen the current preferred format would be [[Bloody Sunday (Northern Ireland)]] but the article appears to have been started before that was the practice. Your approach is a sound one but should be in the format [[Bloody Sunday (Ireland 1920)]] and [[Bloody Sunday (Ireland 1972)]]. There is always the risk that this approach to the 1972 massacre could be seen as supporting a united Ireland. If you see that as a realistic fear than I would suggest using the city names for the events [[Bloody Sunday (Dublin)]] and [[Bloody Sunday (Derry)]]. Nobody can argue that these town aren't where they are.
