Claim: Heinrich Sahm was the first High Commissioner of the Senate in the Free City of Danzig and we twice re-elected to the office.
Evidence: After the establishment of the Free City of Danzig in 1920, Sahm became first President of the Senate, the de facto head of state beneath the High Commissioner of the League of Nations. In the Free City of Danzig (1920–1939, 1945), the Senate (or Senat in German) was the executive branch, with Senators (Senatoren) being the holders of ministerial portfolios. In Danzig the president of the Senate (Präsident des Senats) was an office equivalent to that of prime minister in other countries.
