It is common belief that Jews arrived in Catalunya as early as the first century with Roman expansion across the Mediterranean, though we have little evidence of this. In the 9th century, we see the first document with mention of a Jew called Juda, who came from France, however there is little documented evidence until the 11th century. From then, the community began to grow, Barcelona becoming one of the largest Jewish communities in the Catalan Aragon territory of the middle ages.
