A number of free grammar schools for bright boys were set up hundreds of years ago. Because they were free, they were labelled �public' schools. Over centuries, many began to take fee-paying pupils alongside the scholarship boys for which the schools had been founded. The position is, of course, reversed today, with fee-paying pupils vastly outnumbering the scholarship ones. Many also now take girls.
Here's an extract from the
Encyclop�dia Britannica's article on British public schools...
"The typical great public school evolved from an institution"...ie 'a grammar school'..."founded by a single benefactor during the late European Middle Ages or Renaissance"...ie 'hundreds of years ago'... "Such charitable foundations, almost invariably for males only, had usually been intended to educate local boys from relatively humble backgrounds."...ie 'scholarship boys'..."From about the 17th century the upper classes took increasing advantage of the tuition afforded by these foundations. As pupils paying the market rate became more numerous, the schools were increasingly transformed into boarding establishments."

The Headmasters' and Headmistresses' Conference is the body to which all major British independent schools belong. All of them would consider themselves to be �Public Schools' as defined nowadays.
