What did emperor claudius the second ban?

If Claudius II Gothicus would have banned something it would have been Christianity. However, this notion is discredited by modern historians.

There are some medieval legends which say that Claudius martyred St Valentine during a persecution of Christians. Modern historians strongly doubt these stories. His reign was short, only two years, and he was busy with war. He had to deal with a Gothic invasion across the river Danube and then an invasion of Italy by the Alemanni. After that he fought a usurper emperor who had seceded from the empire and was ruling Britannia, Gaul and Spain. He won several battles and succeeded in regaining control of Spain and southeastern France. Shortly before his death he was preparing to fight an invasion by the Vandals. He would hardly have had any time to persecute the Christians Such action also would not have been advisable during a period of war. Moreover, there is no evidence that he reversed the previous emperor's (Galienus) policy of toleration of Christianity, a policy which lasted for 43 years until Diocletian's Great Persecution. The legends talk about emperor Claudius without specifying whether they mean Claudius or Claudius II. One legend gives 270 as a date, the year when Claudius II died.
