Before Wales was known as Wales, it was called by a different name. The previous name of Wales was Cymru, which means "fellow-countrymen" in Welsh. The origin of the word Wales itself is believed to be derived from the Anglo-Saxon word "Wealas" or "foreigners."

As far back as we can trace, Wales has been known as Wales for over a thousand years. The name has ancient roots, dating back to the Anglo-Saxon period when the term "Wealas" was used to refer to the Celtic people living in what is now Wales.

Over time, the name evolved into "Wales," and it has been used to refer to the country ever since. The name change reflects the shifting political and cultural landscape of the region over the centuries.

It is interesting to note that the Welsh language, Cymraeg, has remained relatively unchanged over the years compared to other Celtic languages. This continuity is a testament to the resilience of Welsh culture and identity throughout history.

In conclusion, Wales was known as Cymru before it became known as Wales. The origin of the word Wales can be traced back to the Anglo-Saxon term "Wealas," which referred to the Celtic inhabitants of the region. The name change reflects the complex history of Wales and its people, who have maintained a strong sense of identity and culture over the centuries.
