The question why Tribal Zone expanded from first century BCE onwards and took the place of all Arabian states except those at the northernmost and southernmost fringes, is still not settled. Scholars implicate a few factors.
The Economic Decline
The inland incense trade was the lifeline of the economy in the first century BCE. Diodorus Siculus describes the people of Yemen as richer than any other group he knows of. “The farthest parts [of Arabia], Arabia Felix (Arabia the Happy), produce myrrh and frankincense, which is carried all the world over,’ Diodorus tells, explaining the reason for them being rich.1 Soon after the comments of Diodorus Siculus, the inland trade of myrrh and frankincense suffered a great setback. In 25 BCE, a Roman army attacked Arabia from the land of Egypt and reached Yemen. Once they discovered (or rediscovered) the caravan route and the land of incense, they turned the trade to the sea.2 Both Strabo and Periplus Maris Erthyrae describe the growth of maritime traffic in the first century CE between Roman seaports of Egypt, Arabia, and India, just after the Roman invasion of Yemen.3 The monopoly of Arab middlemen weakened, and they had to adjust their profits. The incense trade suffered a further serious blow when the price of incense crashed in international markets due to the political and economic crises that the Roman Empire experienced by the middle of the 3rd century CE.4
The Environmental Changes
Lately, some historians are suggesting environmental changes, which led to an economic crisis, which later on resulted in Bedounization of Arabia.5
