Treaty on the Final Settlement with Respect to Germany
After the War, the so-called "German question" was an important factor of post-war German and European history and politics. The debate affected Cold War politics and diplomacy and played an important role in the negotiations leading up to the reunification of Germany in 1990. In 1990 Germany officially recognized its present eastern border at the time of its reunification in the Treaty on the Final Settlement with Respect to Germany, ending any residual claims to sovereignty that Germany may have had over any territory east of the Oder–Neisse line.
