Limerick is distinguished in history as "the city of the violated treaty;" and the Shannon, on which it stands, has been aptly termed "the King of Island Rivers." Few of the Irish counties possess so many attractions for the antiquarian and the lover of the picturesque: and with one exception, no city of Ireland has contributed so largely to maintain the honor and glory of the country. The brave defenders of Limerick and Londonderry have received--the former from the Protestant, and the latter from the Catholic, historian--the praise that party spirit failed to weaken; the heroic gallantry, the indomitable perseverance, and the patient and resolute endurance under suffering, of both, having deprived political partizans of their asperity--compelling them, for once at least, to render justice to their opponents; all having readily subscribed to the opinion that "Derry and Limerick will ever grace the historic page, as rival companions and monuments of Irish bravery, generosity, and integrity." From a very early period Limerick has held rank among the cities of Ireland, second only to that of the capital; and before its walls were defeated, first, the Anglo-Norman chivalry; next, the sturdy Ironsides of Cromwell; and last, the victorious array of William the Third. Like most of the Irish sea-ports, it was, in the ninth and tenth centuries, a settlement of the Danes, between whom and the native Irish many encounters took place, until finally the race of the sea-kings was expelled from the country. It is certain that at this early period Limerick was a place of considerable importance; for some time after, indeed until the conquest by the English, it was the capital of the province, and the seat of the kings of Thomond, or North Munster, who were hence called Kings of Limerick. Upon the arrival of Strongbow, Donnell O'Brien swore fealty to Henry the Second, but subsequently revolted; and Raymond Le Gros, the bravest and noblest of all the followers of Strongbow, laid siege to his city. Limerick was at that time "environed with a foule and deepe ditch with running water, not to be passed over without boats, but by one foord only;" the English soldiers were therefore discouraged, and would have abandoned the attempt to take it, but that "a valiaunt knight, Meyler Fitz-Henry, having found the foord, wyth a loud voyce cried 'St. David, companions, let us corageouslie pass this foord.'" For some years after the city was alternately in the possession of the English and the Irish; on the death of Strongbow, it was surrendered to the keeping of its native prince, who swore to govern it for the King of England; but the British knights had scarcely passed the bridge, when he destroyed it and set fire to the town.
