Foundation and First Mentions
The history of Anglesey (in Welsh — Ynys Môn) is rooted in the prehistoric era. It is not a classic city founded on a specific date, but an island region with ancient settlements. The first significant mentions in written sources date back to the 1st century AD and are linked to the Roman conquest of Britain.
The Roman historian Tacitus described the island as a sacred stronghold of the druids and a centre of resistance against the Romans. The modern name "Anglesey" is of Scandinavian origin and appeared much later, during the Viking Age (around the 10th century), likely meaning "Ongull's Island".
Key Factors of Formation
The development of the region was defined by a unique combination of geographical and political conditions:
- Strategic Geography: The island is separated from the mainland of Wales by the Menai Strait, which historically made it a natural fortress convenient for defence.
- Political Power: In the early Middle Ages (from the 6th century), the village of Aberffraw hosted the main court of the Kings and Princes of Gwynedd, one of the most powerful Welsh kingdoms. This gave Anglesey the status of the political heart of North Wales.
- Maritime Trade: Its location in the Irish Sea facilitated active exchange with Ireland and the Isle of Man, although it also made the coastline vulnerable to raids.
Early Cultural and Economic Features
The economy of early Anglesey was based on agriculture. Thanks to its mild climate and fertile soils, the island earned the famous nickname Môn Mam Cymru ("Mona, the Mother of Wales"). It was believed that the harvests gathered here could feed all of Wales in times of famine.
Culturally, the island remained a guardian of Celtic traditions, language, and spirituality for many centuries, preserving its identity even after the construction of the famous castles by the English King Edward I in the 13th century.
