Channel Islands, a group of islands in the English Channel, near the coasts of Normandy and Britanny, in France. The chief are Jersey, Guernsey, Alderney, and Sark, and others are Herm, Jethou, Le Marchant, and the Caskets. They were known to the Romans, were early occupied by the Gauls, were an asylum of refugee Britons fleeing from the Roman power in England, received Christianity early in the 6th century from Wales, were ceded by France in 912 to Rollo, first Duke of Normandy, continued to be held by William, the seventh duke, at his conquest of England, and though frequently attacked by France, and sometimes severely shaken by political changes in England, have, with slight interruption, remained ever since annexed to the English crown. The several islands will be separately described in separate articles in their alphabetical order.
