Palatine Lion
After the Second World War the Palatinate Lion re-emerged as the regional symbol of the Palatinate, for example, on postage stamps in the French Zone of Occupation. Following the creation of the state of Rhineland-Palatinate in 1946, to which the Palatinate belonged, the Palatine Lion occupied a central place in the state coat of arms of Rhineland-Palatinate. The other elements of the Rhineland-Palatine coat of arms are the Wheel of Mainz ("Mainzer Rad") and the Cross of Trier ("Trierer Kreuz"). Even the semi-official coat of arms of the Province of Palatinate, which existed from 1946 to 1968 and dated to the 19th century, bore the Palatine Lion, which after the inclusion of the former territories of Electoral Mainz and Electoral Trier, symbolised the region of the present-day Palatinate.
Palatinate (region)
The union with Bavaria was finally dissolved following the reorganisation of German states during the Allied occupation of Germany after World War II. While Bavaria itself was part of the U.S. occupation zone, the Palatinate was occupied by French forces. The French reorganised their occupation zone by founding new states, so that in 1947 the Palatinate was combined with Rhenish Hesse ("Rheinhessen"), the former parts of the People's State of Hesse left of the Rhine, and the southern part of the Prussian Rhine Province, to form the German federal state of Rhineland-Palatinate. The Palatinate formed the administrative district ("Regierungsbezirk") Pfalz. 
This reorganisation came with smaller losses of former district territory to the Saarland, especially in the area of Sankt Wendel. As part of the 1969 administrative reform, some minor border changes were made in the north. The Diocese of Speyer and the Evangelical Church of the Palatinate still exist today largely based on the historic boundaries of the old Bavarian district of "die Pfalz".
