A process of standardisation started in the Middle Ages, especially under the influence of the Burgundian Ducal Court in Dijon (Brussels after 1477). The dialects of Flanders and Brabant were the most influential around this time. The process of standardisation became much stronger at the start of the 16th century, mainly based on the urban dialect of Antwerp. In 1585 Antwerp fell to the Spanish army: many fled to the Northern Netherlands, where the Dutch Republic declared its independence from Spain. They particularly influenced the urban dialects of the province of Holland. In 1637, a further important step was made towards a unified language, when the Statenvertaling, the first major Bible translation into Dutch, was created that people from all over the new republic could understand. It used elements from various, even Dutch Low Saxon, dialects but was predominantly based on the urban dialects of Holland of post 16th century.

However, the Orthodox claim to absolute fidelity to past tradition has been challenged by scholars who contend that the Judaism of the Middle Ages bore little resemblance to that practiced by today's Orthodox. Rather, the Orthodox community, as a counterreaction to the liberalism of the Haskalah movement, began to embrace far more stringent halachic practices than their predecessors, most notably in matters of Kashrut and Passover dietary laws, where the strictest possible interpretation becomes a religious requirement, even where the Talmud explicitly prefers a more lenient position, and even where a more lenient position was practiced by prior generations.
