Claudius is sent to put down the revolt in Mérida after a count named Witteric had exposed the plot of Sunna, the city's Arian bishop, to place the Visigoth Segga on the throne and probably to also kill the Catholic Méridan bishop Masona in 587.

Segga is captured, his hands cut off (the penalty for usurpers), and banished to Galicia.

The less important conspirators are deprived of their property and offices and sent into exile, but one of the chief rebels, Vagrila, takes refuge in the basilica of Saint Eulalia.

Claudius is told, upon request, to give Vagrila, his family, and his possessions over to the church of Mérida, which he does.

Masona, however, releases Vagrila and his family and returned his property to him.

Reccared I sends word of his conversion to Catholicism early in 589 to Septimania, where it incites a rebellion on behalf of Arianism by two prominent counts, Granista and Wildigern, and the bishop Athaloc.

The rebels seek to overthrow Reccared and the Catholic faith and to this end they call in the aid of the Catholic and Frankish king of Burgundy, Guntram.

Guntram sends an expedition under the general Boso into Septimania in support of the rebellion against Visigothic rule.

Claudius, duke (dux) of Lusitania, defeats the Franks and Burgundians at Carcassonne on the Aude River, killing five thousand and capturing two thousand, as well as their camp.

Many Catholics die in the process of the rebellion.

Athaloc, however, is not deposed and will die a natural death, never converting to Catholicism.
