It was the party of Empire, the King and the flag, and that was good enough for him

Powell was a man of almost obsessive passions, from Housman and Nietzsche to High Anglicanism and hunting. He was, in short, a nineteenth-century romantic, zealous and uncompromising, a man of causes. His decision to join the Conservative Party, for example, was based less on social and economic principles than on sheer romantic traditionalism. It was the party of Empire, the King and the flag, and that was good enough for him.
