Dutch Americans
While the Netherlands was a small country, the Dutch Empire was quite large so emigrants leaving the mother country had a wide variety of choices. New Amsterdam was not high on their list, especially because of the Native American risk. The major Dutch cities were centers of high culture, but they still sent immigrants. Most new arrivals were farmers from remote villages who, on arrival, in America scattered into widely separated villages with little contact with one another. Even inside a settlement, different Dutch groups had minimal interaction. With very few new arrivals, the result was an increasingly traditional system cut off from the forces for change. The people maintained their popular culture, revolving around their language and their Calvinist religion. The Dutch brought along their own folklore, most famously "Sinterklaas" (the foundation of the modern day Santa Claus) and created their own as in "The Legend of Sleepy Hollow". They maintained their distinctive clothing, and food preferences and introduced some new foods to America, including beets, endive, spinach, parsley, and cookies.
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.
