At the end of the 12th century, the kings of Ireland had been fighting amongst themselves, and the high king got involved, and what with one thing and another Diarmait Mac Murchada, who had been the king of Leinster, and then had been ousted, and then had gotten in again, got ousted again, and then had the very bad idea of getting help from the Anglo-Normans. And they did help, didn't they, and then they took Ireland over.  This could have been foreseen by anybody who had been paying attention to how the Normans operated.  Diarmait, at any rate, got to be king again, though not for long, and then he got to live in infamy as a great traitor.  For the  Irish. The English liked him better. Michelle gets even more exercised than usual, because 1) colonialism, very bad, and 2) some scholars she found, also very bad.
