George, Duke of Saxony
Bildts () is a Dutch-West Frisian hybrid language spoken in the largest part of the former municipality Het Bildt (ca. 1505–2017) in the Dutch province of Friesland. The dialect evolved from the early sixteenth century onwards, from around 1505, when the area was reclaimed from the sea as ordered by George, Duke of Saxony. In order to achieve this task, workers from Holland, Zeeland, and Brabant moved to Friesland, and their Low-Franconian dialects mixed with West Frisian. There has been debate on whether the former changed the latter or the other way around, but the dialect has also been called a creole language.
