Вольный город Данциг
The Social Democratic Party of the Free City of Danzig () was a political party in the Free City of Danzig. After the creation of the Free City of Danzig in 1919, the Danzig branch of the Social Democratic Party of Germany (SPD) separated itself from the party, and created the Social Democratic Party of the Free City of Danzig. The new party did however maintain close links with the SPD, and its political orientation (for example its anti-Soviet/anti-communist approach) was largely the same as that of the SPD.
