Mogador and the Zenet sea-nomads.
Once upon a time, Europe was inhabited by two groups of people, one in the south-west, and one in the north-east (today known as the Basques and the Berbers). The Celtic progression in Europe chased the north-east Europeans toward the shores of North Africa and even to the Canary Islands.
In the first century AD, a Roman soldier comes to a Roman outpost on the Atlantic coast of today's Morocco, with the message of Josuha of Nazareth, son of Miriam and Yosef, the Messiah Jews have waited for so long.
Around 680 AD, the Arab Islamic expansion reaches the shores of the Atlantic. It is not well accepted by these Berbers, converted to a Christian Judaism, who call themselves "Chenech" or "Zenet". Most of them being fishermen, they leave north Africa by way of the sea. Some sail southward to the Canary; others, north to the Algarve coast of Portugal. As the Arabs invade the Iberian Peninsula, the Zenets sail northward to end up on the shore of what is now Galicia, north west of Spain. There, they take the Celtic language shared by the minority of these regions who refuse the Latin dialect spoken elsewhere. By the turn of the millennium, their population increases and many are forced to sail further along the Cantabrian coast to the Basque country.
