Trier (region)
administrative district in Rhineland-Palatinate (1815–1999)
Trier was one of the three Regierungsbezirke of Rhineland-Palatinate, Germany, located in the west of the state.
History
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.

Why this record matters
“Trier (region)” is worth following because a concise public description often conceals a longer documentary argument. Here, Trier, region and administrative provides the most credible route into that argument.
Maps, plans, fabric surveys and administrative records can establish how the site’s name, extent and function changed over time. The source revision retrieved here is dated Nov 15, 2025. The linked authority identifier is Q573203. VIAF identifies the subject as 147797588. The Library of Congress control number is n84112366. Authority coordinates are 49.777, 6.633. 2 of 4 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1815, 1920, 1937 and 1946.
Modern boundaries and familiar names can conceal earlier jurisdictions or structures that do not align with the present site. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
