The island of Ven was added to the City of Landskrona in 1959. The amalgamations leading to the present municipality took place in 1967, 1969 and 1974. Since 1971 it is a municipality of unitary type, like all other municipalities of Sweden. The municipality, however, prefers to style itself Landskrona stad (City of Landskrona). This is purely nominal and has no effect on the status of the municipality.
