 English distinguishes between "Franks" (the early medieval Germanic people) and "Franconians" in reference to the high medieval stem duchy, following Middle Latin use of "Francia" for France vs. "Franconia" for the German duchy.In German the name "Franken" is equally used for both, while the French are called "Franzosen", after Old French "françois", from Latin "franciscus", from Late Latin "Francus", from "Frank", the Germanic tribe.The Franconian lands lie principally in Bavaria, north and south of the sinuous River Main which, together with the left (southern) Regnitz tributary, including its Rednitz and Pegnitz headstreams, drains most of Franconia.
