Interbellum Polish Masuria — the Działdowo county thumb|right|Aerial view of Działdowo The region of Działdowo (Soldau), where according to the official German census of 1910 ethnic Germans formed a minority of 37.3%, was excluded from the plebiscite and became part of Poland. This was reasoned with placing the railway connection between Warsaw and Danzig (Gdańsk), of vital importance to Poland as it connected central Poland with its recently obtained seacoast, completely under Polish sovereignty. Działdowo itself counted about 24,000 people of which 18,000 were Masurians.Andrzej Sakson, Mazurzy: Społeczność pogranicza, Instytut Zachodni, 1990, page 59.
