Ok although I realise this has been touched on before I’m still interested in what people have to say. The battle of the Boyne and the Irish campaign was ultimately won by the multi national army led by William of Orange and his allies. English and Protestant political dominance over the islands was emboldened and cemented following this war only to be threatened later the next century. However what if the Jacobite has won? Would James vii of then restored the Stuart’s to the British crown? Would he of granted some sort of independence to the Irish as he had promised along with religious tolerance? How would World ppolitics have been affected? Would the future Irish famines and mass migrations been butterflies away?
