Why did king clovis converted to Christianity?

Clovis converted from paganism to Catholicism at the instigation of his wife, Clotilde, who was a Burgundian Catholic. He had rested this. He refused to allow Clotilde to baptise their son, but she did this behind his back. The child died soon afterwards and this entrenched Clovis' resistance. The same thing happened again with their second son.

It is thought that Clovis converted to Catholicism to gain the support of the Catholic Gallo-Roman aristocracy of his kingdom and to distinguish himself from the other Germanic kings, who were Arian Christians.
