Rhenish Franconia (German: Rheinfranken) or Western Franconia (German: Westfranken) denotes the western half of the central German stem duchy of Franconia in the 10th and 11th century, with its residence at the city of Worms. The territory located on the banks of Rhine river roughly corresponded with the present-day state of Hesse and the adjacent Palatinate region in the south.
