As a result of 19th-century industrialisation, Salford has had ""a special place in the history of the British working class""; together with Manchester it had the world's ""first fully formed industrial working class"". Salford has not, in general, attracted the same minority ethnic and cosmopolitan communities as in other parts of Greater Manchester, although it did attract significant numbers of Irish in the mid-19th century. Many migrated to Salford because of "the Great Hunger" in Ireland combined with Salford's reputation as a hub for employment in its factories and docks. In 1848, Salford Roman Catholic Cathedral opened, reflecting the large Irish-born community in Salford at that time.
