Wales. The act stated that Wales was already ‘incorporated, annexed, united and subiecte to and under the imperialle Crown of this Realme as a very member…of the same’. The 1536 act, according to Dr John Davies unified the principality of Wales and the March of Wales. The law of England was applied as the only law in Wales. The act also made English the only language of the courts in Wales and those using the Welsh language would not be able to take up office in the territories of the king of England. The implementation of the act was delayed until a more detailed act was used in 1543.
