When the tribal leadership adopted a new god the tribe followed suit. Not to have done so would have been tantamount to rebellion. When Charlemagne insisted on baptism and become a christian and as the sign of submission, he punished with appalling barbarity any resistance, as when, in cold blood, he beheaded, in a single day, 4,500 Saxons at Verden, in 782 CE. This is a glaring truth about religion, it is tyranny to its fullest.
