This document analyzes the historical development of privacy and data protection rights in the constitutions of EU member states. It finds that while privacy rights relating to the home and correspondence date back to the early 19th century, general privacy and data protection rights are more recent additions, emerging in the late 20th century. Currently, general privacy rights are recognized in most EU constitutions, while data protection rights are recognized in about half. Data protection rights also tend to be more specific than general privacy rights. The document concludes that while privacy and data protection rights have developed together, privacy rights remain more commonly adopted at the constitutional level.
