Ile-de-France is a
region of
France. It includes the
capital,
Paris.
The name first appears in
1387, replacing the older "Pays de France" when the word
pays began to mean
nation rather than
region. (source:
Quid). It means, literally, "Isle of France": this is taken as meaning the inland
peninsula delimited by the
Oise[?],
Seine,
Ourcq[?] and
Marne[?] rivers.
