He was one of the supporters of the autonomy movement of the Poles of the Vilnius/Wilno region, that had been part of Poland before being attached to Lithuania in 1939.
The Polish autonomist movement (the leaders of which included Jan Ciechanowicz) was related to the Yedinstvo movement and had tacit support from Moscow (thus, when following the Act of the Re-Establishment of the State of Lithuania the Soviets applied a blockade against Lithuania, the areas of Eastern Lithuania with significant minority population were mostly spared of the blockade, with the aim of gaining minorities' support for Moscow).
