At its height, the Kingdom of Mann and the Isles stretched from the Hebrides to Dublin. The parliament had 32 members — 16 from the island and 4 from each of four groups of Hebridean islands: Lewis, Skye, Mull, and Islay.

Representatives arrived at Tynwald by boat, crossing hundreds of miles of open water.

Mark the full extent of the sea kingdom on a large map. Mark each island group. Then calculate: how far did the Lewis representatives have to sail? What route would they take? How long in a Norse longship?

A parliament held together by ships and kinship and the authority of a king who ruled from Castle Rushen.
