Societies have always had healers, but not all healers were recognized in
the same way. Licensing emerged when rulers, courts, towns, universities,
guilds, and later states tried to separate authorized practitioners from
unapproved competitors.
In medieval and early modern Europe, medical authority was divided among
university-trained physicians, surgeons, barber-surgeons, apothecaries,
midwives, empirics, household healers, and religious institutions. A
license might depend on a university degree, a guild examination, civic
permission, patronage, or membership in a college.
Formal regulation developed through courts, universities, guilds,
churches, and towns. In the Kingdom of Sicily, Frederick II's
thirteenth-century legislation required medical training and examination.
English towns and universities likewise developed rules for who could
treat the sick. A 1511 statute authorized bishops to license physicians
and surgeons, and Henry VIII granted the College of Physicians its
charter in 1518. Surgery was regulated separately through guilds,
including London's Company of Barber-Surgeons, created in 1540.
These arrangements were local and uneven. A practitioner authorized in
one city might have no standing in another, and formal rules often
coexisted with customary practice. The result was not a single medical
profession, but a contested field of overlapping jurisdictions.
