The Laws in Wales Acts 1535 and 1542, also known as the "Acts of Union", passed by the Parliament of England, annexed Wales to the Kingdom of England, and replaced the Welsh language and Welsh law with the English language and English law. In particular, Section 20 of the 1535 Act made English the only language of the law courts and stated that those who used Welsh would not be appointed to any public office in Wales. The Welsh language was supplanted in many public spheres, with, for example, the use of the Welsh Not in some schools. This would later be adopted as a symbol of English oppression.
