This article concentrates on one particular local cross-border activity carried on after the Second World War. This was a type of smuggling called joppaus in the local dialect, a practice which was enabled by the post-war economic recession and the scarcity of goods from which Finland suffered. This form of unauthorised economy is said to have been responsible for the rapid revival of the region and its inhabitants after the destruction inflicted by the war. The standard of living in the Tornio River Valley has been better than in the north of Finland in general, and this has been explained in part by this type of smuggling. Furthermore, in the last few decades joppaus has become part of the local cultural heritage.
