Latvia recognsed de jure by Germany
Latvia declared independence in 18.11.1918, but de facto its territory was still under control of Russian and German forces.
The German-White Russian joint attempt in destroying the Latvian independence in November 1919 resulted the declaration of war against Germany.
After the initial defeat of the army of Bermont, Latvia received German radio message that the Army of Bermont is now under the command of the State of Germany. Previously it was supposed to be under command of the White Russian general Yudenich. After Latvian received the confirmation from the German Foreign ministry; the Latvian government concluded that Latvia is at the state of war with Germany.
On November 25 Latvia issued a note to Germany of entering the state of war and cancelation of all diplomatic relations. Ironically the German government did not understand the reason for this declaration of war and replied that Germany is in no means in the state of war with Latvia.
After the final defeat of German reactionary forces in 1919 Finland, Poland, Lithuania, Estonia, Belgium and France recognized Latviade facto.
At the first half of 1920 the western powers discussed the de iure recognition of the Baltic independence. Italy and Japan was supportive, France was elusive about it, but the US was strictly against it.
US were skeptical about the long lasting of the Baltic States and feared that other territories in Far East may break away from Russia favoring Japan.
Also Poland was quite hesitant of the de iure recognition since it would mean that it had to give up its claims for Latgalian region.
After complete defeat of the Soviet forces in Latvia the peace talks with Germany and the Soviet Russia begun. Latvian side presented documents proving German extended support for the Bermot army. Germans became more compliant and promised to acknowledge Latvia as de iure after the Entente powers do this. Germans also gave indefinite promise to compensate the war losses done by German military formations. Germans also proposed not to call the coming agreement as Friedensvertag (peace agreement) but simply Vertag (agreement) since they still did recognized that they are in the state of war with Latvia.
