 Creagh played a significant role in launching the “Limerick boycott” of 1904–06, in which many non-Jews economically boycotted, on an antisemitic basis, the small Jewish community in Limerick.The boycott was accompanied by a number of antisemitic assaults and intimidation, and caused some Jews to leave the city.The boycott and associated events are sometimes referred to as the "Limerick pogrom" (a name derived, in part, from the Eastern European origins of many Jews in Limerick).
