The title of this article is consciously provocative, and thus cries out for immediate explanation and perhaps, in some sense, for the provocation to be disarmed. Why, then, is ‘Was Ireland a colony?’ a bad question - or rather, a question often badly posed? Reasons include the fact that the question is so intertwined with other disputes, including directly political ones, and because there are problems with the term ‘colony’ itself, which has in so many varied contexts been overworked, under-theorised and even under-defined. The oversimplified, stark ‘either/or’ nature of the question is also problematic, when it would be more productive, and perhaps more precise, to think in terms of colonial features in combination with others, if not, indeed, of graduations and degrees of coloniality.
