The Laws in Wales Acts 1535 and 1542 (Welsh: Y Deddfau Cyfreithiau yng Nghymru 1535 a 1542) or the Acts of Union (Welsh: Y Deddfau Uno), were Acts of the Parliament of England under King Henry VIII of England, causing Wales to be incorporated into the realm of the Kingdom of England.
The legal system of England and the norms of English administration including the use of the English language only were applied to a mainly Welsh-speaking Wales. This created a single state and legal jurisdiction, which is now called England and Wales.
Before these Acts, Wales had already been annexed by England in 1284 and was excluded from parliamentary representation. Wales was divided between the Principality of Wales and many feudal statelets called the marcher Lordships which were effectively unified under the laws. The English county system was also extended across all of Wales.
