From 1893 to 1899, Weber was a member of the Alldeutscher Verband (Pan-German League), an organization that campaigned against the influx of the Polish workers; the degree of Weber's support for the Germanisation of Poles and similar nationalist policies is still debated by modern scholars.[1][2] In some of his work, in particular his provocative lecture on "The Nation State and Economic Policy" delivered in 1895, Weber criticises the immigration of Poles and blames the Junker class for perpetuating Slavic immigration to serve their selfish interests.[3]: 1–28
