Hordaland – a historic region

“It was on such a chilly, silver-grey morning that the Hørde folk, the Harudes of Caesar and Tacitus, must have come running in from the sea on the wind at sunrise; at last from the Danish peninsula in the final phase of the great Folk migration, as it either crumbled under the overwhelming superior power or was pushed forward only by small folk, from the misery of many years of famine, just like the early settlers of Iceland to find better long-lasting homes; they took land for one reason or another not on the southern tip of Norway or Lister, but north of Karmøen and in the fjords of Hardanger, they sought shelter from the sea winds”  This is the poet Hans E.Kinck’s lively description in his book: “Places and folk” of the emigration of the Horda people to western Norway.
