While southern Ireland was clamouring for repeal of the Union with Britain, Ulster came round to the view that Union with Britain suited her better than any form of self-government for Ireland. For one thing she saw that the Union was to her economic advantage, since she was far more industrialised than the agricultural south, and her future clearly depended on the continuance of friendly trade with Britain., Due to the industrial revolution Belfast had grown bigger than Dublin. Ulstermen were proud of their achievements and would have seen them as proof of the Weberian theory of the "Protestant work ethic".
