There were intermarriages between the three Gothic kingdoms, in Burgundy, Gaul, and Spain, and the history of some of these royal families shows what wild passions still raged among the Goths, and what atrocities were strangely mingled with ambitious projects and religion. Athanagild, one of the Visigoth kings, gave his daughter Brunhilde in marriage to the King of the Franks in Gaul.
But Fredegonde's hour had not yet come; for Chilperic espoused Galsuinthe, daughter of the Visigothic king, Athanagild, whose youngest daughter, Brunehaut, had just married Chilperic's brother, Sigebert, king of Austrasia. It has already been said that before long Galsuinthe was found strangled in her bed, and that Chilperic espoused Fredegonde.
He forsook Ingoberge, and took to wife Meroflede. Charibert afterwards espoused Marcovive, sister of Meroflede; and for that cause both were excommunicated by St. Germain, bishop of Paris. Chilperic, fourth son of Clotaire I. and king of Soissons, "though he had already several wives, asked the hand of Galsuinthe, eldest daughter of Athanagild, king of Spain.
In Spain, Justinian obtained Corduba, Assidona, Segontia , in reward of the assistance which he had rendered to Athanagild against a competitor for the throne.
Family contests, and wars full of horrors, in which the tragic feud of two women, Brunhilde of Austrasia, a daughter of Athanagild, king of the Visigoths, and Fredegunde of Neustria, played a prominent part, ensued. In 613 Clotaire II. of Neustria united the entire kingdom. Brunhilde was captured, and put to death in a barbarous manner. The son of Clotaire, Dagobert, was a worthless king.
Clovis, in the north of France, the Burgundian chieftain at Arles, Theodoric in Italy, Athanagild later at Toledo in Spain, were all of them men who had stepped into the shoes of an unbroken local Roman administration, who worked entirely by it, and whose machinery of administration wherever they went was called by the Roman and official name of Palatium.
