IOTL indudustrialisation in Ireland was focused on Belfast due to its placement as a good position for shipbuilding. Over time Belfast became home to one of the world's biggest shipbuilders (Harland and Wolff) and the centre of Ireland's linen industry. This industrialisation, and the wealth it brought, helped plant the seeds of Ulster's fight against Home Rule (Ulster's Protestants believing that being lumped with a mostly still agrarian Ireland would drag them down and damage their newfound prosperity).
So this led me to pose this question to the good folks of AH.com. If industrialisation was more widespread throughout Ireland, or focused somewhere other than Belfast, how would this alter the development of Ireland, in particular Ireland's campaign for Home Rule and the relationship between Protestants and Catholics?
