What was the last country reported as being liberated from the Nazis?

According to historical records, the last country reported as being liberated from the Nazis was the Netherlands. This European country was occupied from May 10, 1940 until May 20, 1945.

The Reichskommissariat Niederlande was the civilian occupation regime set up by Nazi Germany in the German-occupied Netherlands during World War II. Its full title was the Reich Commissariat for the Occupied Dutch Territories (Reichskommissariat für die besetzten niederländischen Gebiete). The administration was headed by Arthur Seyss-Inquart, formerly the last chancellor of Austria before initiating its annexation by Germany (the Anschluss).

The German domination of the Netherlands began with a German invasion. On the day of the capitulation (May 15) the country's entire ministerial staff fled to London to form a Dutch government in exile. Queen Wilhelmina, the previous day, had already preceded them out of the country. German military administration was initially implemented, led by Militärsbefehlshaber Alexander Freiherr von Falkenhausen. This was quickly disbanded however to be replaced by a civil administration under the authority of the newly appointed Arthur Seyss-Inquart.

For almost 4 years the Nazis had control of the Netherlands, then from September 1944 to mid-1945, the Reichskommissariat came under attack from Allied forces. The Canadian Army was given the initiative to liberate the Netherlands. They forced the German Army to surrender and abdicate its claim in May 1945.
