 In 1752, the Gregorian calendar was also adopted in Ireland.However, even after this date, "The Twelfth" continued to be commemorated at Aughrim, on 12 July NS, following the usual historical convention of commemorating events of that period within Great Britain and Ireland by mapping the Julian date directly onto the modern Gregorian calendar date (as happens for example with Guy Fawkes Night on 5 November).But, after the Orange Order was founded in 1795 amid sectarian violence in County Armagh, the two events were combined in the late 18th century.
