PostDecline of the Anglo-Irish Aristocracy (Harry Papasotiriou, Greece, 08/29/20 8:39 am)
A very comprehensive and dispassionate book on the fall of the aristocracy across the United Kingdom is David Cannadine's The Decline and Fall of the British Aristocracy (Anchor Books, 1990).
It has much to say about the decline of the aristocracy in Ireland. A key measure was the Irish Local Government Act of 1898, passed by the conservative Salisbury government to ameliorate the worst aspects of absentee landlordism and stem the Irish drive for Home Rule. It contributed to the selling by aristocrats of their estates in Ireland but did not end the Irish nationalist drive for independence.
JE comments: Interesting: London believed that reining in the absentee landlords would pacify the restive Irish. The opposite seems to have occurred. Empires rarely found the Goldilocks Mean of providing "just enough" autonomy. Too little and you have rebellion. Too much and you get pretty much the same thing. The moral: avoid empires.
