Dutch diaspora
Emigration from the Netherlands has been occurring for at least four hundred years, and may be traced back to the international presence of the Dutch Empire and its monopoly on mercantile shipping in many parts of the world. Dutch people settled permanently in a number of former Dutch colonies or trading enclaves abroad, namely the Dutch Caribbean, the Dutch Cape Colony, the Dutch East Indies, Surinam, and New Netherland. Since the end of World War II, the largest proportion of Dutch emigrants have moved to Anglophone countries, namely Canada, Australia, New Zealand, and the United States, mainly seeking better employment opportunities. Postwar emigration from the Netherlands peaked between 1948-63, with occasional spikes in the 1980s and the mid-2000s. Cross-border migration to Belgium and Germany has become more common since 2001, driven by the rising cost of housing in major Dutch cities.
Dutch folk dance
Many folk dances regarded as Dutch are probably of Scottish origin, like "Skotse trije", "Skotse fjouwer", "Horlepiep" of "Hakketoone".. This is, because the Dutch are a sea going nation and the fishermen brought many customs, as well as dances, from abroad. The "Horlepiep" is known to be of Scottish origin. In the East of the Netherlands dances like "Driekusman", "Hoksebarger", "Veleta", "Kruispolka" and the "Spaanse Wals" share the origin with German dances, but some are even danced in countries further away, like Poland and Lithuania. Or at least using the same melodies. The actual dances may differ. The "Veleta" used to be a common dance in many parts of Holland during the 1950s till the 1970s on weddings and even in dancings, just like the ballroom dances Waltz, Quickstep and Tango.
