Qualification
The PGA Championship was established for the purpose of providing a high-profile tournament specifically for professional golfers at a time when they were generally not held in high esteem in a sport that was largely run by wealthy amateurs. This origin is still reflected in the entry system for the Championship. It is the only major which does not explicitly invite leading amateurs to compete (it is possible for amateurs to get into the field, although the only viable way is by winning one of the other major championships), and the only one which reserves a large number of places, 20 of 156, for club professionals. These slots are determined by the top finishers in the club pro championship, which is held in June.
Since 1968, the PGA Tour has been independent of the PGA of America. The PGA Tour is an elite organization of tournament professionals, but the PGA Championship is still run by the PGA of America, which is mainly a body for club and teaching professionals. The PGA Championship is the only major that does not explicitly grant entry to the top 50 players in the Official World Golf Ranking, although it invariably invites all of the top 100 (not just top 50) players who are not already qualified.
