What did Philip II do for the reformation?

King Philip II Augustus created a group of salaried civil servants, bailiffs (in the north) and seneschals (in Midi), to administer justice and replace or control the provosts, the traditional rulers of royal estates, guilty of numerous abuses. He multiplies tax revenues, in particular by selling franchise charters and freeing serfs for cash. The king also did not fail to embellish his capital, Paris, and surrounded it with the first line of fortifications, “the aviary of Philip Augustus.”
