Continued Roman Expansions
At Rome's east, however, Mesopotamia, where the capital of the Achaemenids once was was easily conquered by the Romans, giving them a border with the Maurya Empire. From there, the Mediterranean coastline of Arabia was colonized and nominally conquered by the Romans.
Conquest of Kemet
The anarchy faced by what was once the Achaemenids was overcome by the Kemetians. In Kemet (OTL Egypt), worship of Amun-Ra was still occurring. With a stable government, this able land of Kemet was the first real test of the Roman army. Several battles were inconclusive, so the Romans thought they could starve the Kemetians into submission, but this failed due to the fertility of the Nile. Several Greek and Punic expeditions had already determined the source of the Nile to be deep in Africa. These sources were found by the Romans with the help of local peoples and were poisoned. By 160 BC, Egypt surrendered to Rome. This poison would find its way to Greece and ironically to Rome, poisoning and killing several senators.
Rise of the Shunga
By 185 BC, the Maurya were in decline after conquering all of the land outlined by the Ashoka Protocol. A military general named Pusyamitra Shunga wanted power.
Coup against the Maurya
Pusyamitra quickly disposed of the royal family of the Maurya. He conquered Pataliputra (OTL Patna). Outlined in the Ashoka Protocol was that the ruler of Pataliputra is the ruler of Bharat. This meant that all governors of territories are all subservient to Shunga. This began the Shunga Empire.
