The Prussian Settlement Commission, officially known as the Royal Prussian Settlement Commission in the Provinces West Prussia and Posen was a Prussian government commission that operated between 1886 and 1924, but actively only until 1918. It was first up on the initiative of Otto von Bismarck to increase land ownership by ethnically German Germans at the expense of Poles in Germany, by economic and political means, in Prussia's eastern provinces of West Prussia and the Posen as part of his larger efforts aiming at the end of Poles in Germany, the Germanisation of greater territories, in particular those under German rule and strengthening of and ascendancy of “Germandom” and the dominant German culture especially in the “East”, during the Kulturkampf though it survived it, and the end of the Bismarck-era generalised anti-Catholic government policy.
