Anschlussvertrag

Anschlussvertrag is a German term that literally means “accession treaty” or “treaty of joining.” In general use it can denote a legal agreement by which a political entity becomes part of another state or political union. In practice, however, the most famous and debated instance associated with the term is the Incorporation of Austria into Nazi Germany in 1938, often described in historical accounts as an Anschluss rather than as a conventional bilateral treaty.

Historical context and events: In early 1938, pressure from the Nazi regime and pro-German networks within Austria culminated in political turmoil and moves toward unification with Germany. On March 12–13, 1938, German troops crossed into Austria and the Anschluss was proclaimed, integrating Austria into the German Reich. The event was achieved through coercive means and political maneuvering rather than a clearly negotiated mutual treaty between two fully sovereign states. It was quickly followed by administrative fusion and legal instruments at the domestic level within the Reich, and it drew widespread condemnation from many international actors at the time.

Aftermath and legal significance: The Anschluss remained in force until the end of World War II. Following the war, Austria regained full sovereignty in 1955 with the Austrian State Treaty, which included provisions affirming Austrian independence and neutrality and prohibiting a future Anschluss with Germany. In international law and historical writing, the 1938 episode is typically described as an annexation rather than as a standard treaty of accession, and the term Anschlussvertrag is used mainly in historical or methodological discussions about how such mergers have been negotiated or implemented.
