Historically and culturally part of Kashubia and Eastern Pomerania, Gdynia for centuries remained a small fishing village. By the 20th-century it attracted visitors as a seaside resort town. In 1926 Gdynia was granted city rights, after which it enjoyed demographic and urban development, with a modernist cityscape. Until 1939 it was located in the narrow Polish Corridor, between the Free City of Danzig and Germany. Many of its residents were displaced or evicted during the Second World War. The post-war period saw an influx of settlers from Warsaw and other parts of the country as well as Poles from Vilnius and Lviv. The violent protests of December 1970 contributed to the rise of the Solidarity movement in nearby Gdańsk.
