Silesia was initially Austrian and later Prussian, but it never used the Austrian or Prussian colors. The colors white and gold have their roots in the coat of arms. In context with the partition of Silesia in Upper Silesia and Lower Silesia, the latter maintained the silesian flag (→ Silesia).
From 1875, the provinces of Prussia could largely operate in self-governing. There was a provincial parliament and a provincial government (Provincial Committee). Each province had its own colors (Landesfarben), which were also used as flag, and they had also their own coat of arms. If the provincial governments put for official purposes (official flag) their coats of arms on a flag with the provincial colors is not handed down beyond doubt and not for all provinces.
Another incident for the flag was the seizure of power by the National Socialists in the German Empire in 1933. All official non-swastika flags, that refered to federalism, regional references or the old German Empire were abolished between 1933 and 1935. For the National Socialists, the federal structure of the German Empire, its historically grown countries, was considered as outdated, as relics of a past to be overcome. In this sense, several laws were enacted, on 31st of March in 1933 the 'Provisional Law for the phasing of the countries with the Empire', on 7th of April 1933 the 'Second Law for the phasing of the countries with the Empire' and finally, on 30th January in 1934 the 'Law on the rebuilding of the empire'. Thus, the federal structure of the German Empire was replaced by the gau-structure of the NSDAP, the countries became meaningless. From now on, offices and authorities had to use the swastika flag as official flag, until September 15th in 1935, when by the flag-law was legislated a new created official flag for all the offices and authorities of the empire. The prime ministers of the countries, which latest in 1933 all came from the NSDAP – now mostly called Reichsstatthalter (maybe translated as 'governor') – however remained in office until 1945. This was then also applied on the provinces of the state of Prussia. Their sovereign duties were taken over by the Gau structure of the NSDAP, which sometimes coincided with the borders of the provinces and sometimes they were new created. The respective provincial flags disappeared. The corresponding country colours continued, with restrictions, but definitly not in the form of flags. They were used, for example, occasionally on uniforms of the SA or in some ranks of the Hitler Youth in the breast cord.
After the war, the administration within the German Empire was rebuilt, but locally, following the structure of the countries. These have been partly old countries, and some new countries were created. Sometimes they bethought the old country colours and reactivated them – or they created new ones – for limited sovereign duties, which were under the control of the Allies. However, the eastern parts of Prussia were occupied by Soviet troops from 1944, and most of them came under Polish or Russian administration. The process described above did not come into being, the German population was forcibly expelled and the old regional flags no longer played a role.

The name of the country goes back to the Vandal tribe of the Silings, who settled here in the second and third century. Also the Sleza River (German: Lohe) – an affluent of the Oder River – counts as source of the name of the country Silesia.
