According to the Wikipedia page on this topic, since the reign of Abikarib Asʿad (c. 384-433 CE), Judaism was adopted as the de facto state religion of the Himyarite Kingdom. It seems that Judaism may have been adopted to some extent as much as two centuries earlier, but inscriptions to polytheistic deities ceased after this date. It was embraced initially by the upper classes, and possibly a large proportion of the general population over time. Virtually all scholars are in agreement about this except one, who still acknowledges that it definitely makes sense for it to be this way though and even he acknowledges that by the time of Dhu Nuwas's reign (c. 517 - 527 CE) there is basically zero disagreement among the scholars that the king was Jewish, there was presence of Jewish tribal influence and other Jewish influence among the elites as well as the population most likely, the ruling elites and nobles were Jewish, etc.
Taking into account that a Jewish state existed after the exile, how does this impact Jewish beliefs in the sense of, does it deter or delay the arrival of the Messiah? Did they break the Jewish law regarding Jews not being allowed to have a state until the arrival of the Messiah? Does this state existing in the past have any impact on the future of Jews or does it change the laws?
I'm not sure if I phrased this well, but please let me know if I need to clarify since AFAIK Jews aren't allowed to have a state until the arrival of the Messiah, but a Jewish state has apparently existed long before even the contemporary "State of Israel". So how does this work Halachically and what happens now?
