Britain and Ireland
Mounted officer of the British Metropolitan Police, the first modern police force[13]
In England a system of sherriffs, reeves, and investigative "juries" had developed under the Anglo-Saxons to provide basic security and law enforcement.
After the Norman conquest, these institutions remained though their roles changed. Sherriffs in particular were responsible for keeping law and order, although they were responsible to the king and represented his interests.
In the United Kingdom, the development of police forces was much slower than in the rest of Europe. The British police function was historically performed by private watchmen (existing from 1500 on), thief-takers, and so on. The former were funded by private individuals and organisations and the latter by privately funded rewards for catching criminalsPassages Center
