From 1919 to 1925 Preuß was a member first of the Verfassunggebende Preußische Landesversammlung (1919/20), the equivalent of the National Assembly for the Freistaat Preußen, and then the Preußischer Landtag.
He published numerous works on legal and constitutional issues as well as pro-republican writings.
He was also active in the Reichsbanner Schwarz-Rot-Gold.
Hugo Preuß died in Berlin on 9 October 1925.
He is buried at the Urnenfriedhof Gerchtsstraße Berlin-Wedding.
Since 1952 the grave has been an Ehrengrab (honour grave) of what is now the State of Berlin.

The Jewish background of the main author of its constitution was one reason why the Weimar Republic was referred to as Judenrepublik ("Jews' Republic") by its detractors on the right.
