If the Angevin-Normans and later the English had never tried to annex Ireland at any time between he 12th century and the French Revolution, how do you think Ireland would have developed?
How would it have responded to the reformation,the Renaissance, and the trials and tribulations of those centuries?
Would it have united by 1800, or would it still be a patchwork of independent states?
What would it be like in 2015?
