13th century - Adoption of the Flemish law

Probably at the beginning of the second half of the 13th century, Cieszyn adopted the Flemish law from Lwówek in Lower Silesia. Those were the days of the so-called German colonization and the adoption of German law. The new inhabitants and the new law were the source of significant changes: many new town were built, new villages were established and agriculture was improved. Incorporated under the Flemish law and managed by a hereditary commune administrator, Cieszyn gradually changed. The number of inhabitants increased, economic activity developed and the town chancellery was born.
