The region was created in 1815 as part of the Prussian Rhineland . Until 1920 the bulk of what then became the Territory of Saar Basin was part of the Trier Region . Only the east of the Saar Territory , today 's Saar - Palatinate district , formerly the western fringes of the then Bavarian Rhenish Palatinate , was previously no part of the Trier Region . In April 1937 the St. Wendel - Baumholder district , formed in 1920 from those parts of the St. Wendel district that had not been seceded to the Saar Territory , was dissected from the Trier Region and merged in the new Birkenfeld district within the Koblenz Region . After the Second World War the French military government several times extended the Saar area before forming the Saar Protectorate , also including additional 109 municipalities belonging until July 1946 to the Trier Region and some to the Koblenz Region . Koblenz Region 's former areas make up part of today 's St. Wendel district in the Saarland . In December 1946 , when a new customs boundary dissected the Saar Protectorate ( later becoming the Saarland ) from the area under the Allied Control Council over Allied - occupied Germany , the Trier Region with its then remaining territory had become one of the then five regions forming the new state of Rhineland - Palatinate , founded in August 1946 . Later , the French occupation government again redeployed some municipalities -- some returned to Allied - occupied Germany , some newly annexed to the protectorate -- between the Saar area and the new state of Rhineland - Palatinate in 1947 and 1949 , before the border was finally fixed . Since 2000 , the employees and assets of the Bezirksregierungen ( i.e. regional administrations ) form the Aufsichts - und Dienstleistungsdirektion Trier ( ADD ; Supervisory and Service Directorate Trier ) and the Struktur - und Genehmigungsdirektionen ( SGD ; Structural and Approval Directorates ) Nord in Koblenz and Süd in Neustadt ( Weinstraße ) . These administrations execute their authority over the whole state , i. e. the ADD Trier oversees all schools .

Hesse or Hessia (, Hessian dialect: "Hesse" ) is a federal state ("Land") of the Federal Republic of Germany, with just over six million inhabitants.
