In an attempt to shore up his regime, Philip put a great deal of effort into maintaining good relations with the Senate, and from the beginning of his reign, he reaffirmed the old Roman virtues and traditions. He quickly ordered an enormous building program in his home town, renaming it
Philippopolis, and raising it to civic status, while he populated it with statues of himself and his family. He also introduced the Actia-Dusaria Games in
Bostra, capital of Arabia. This festival combined the worship of
Dushara, the main Nabataean deity, with commemoration of the
Battle of Actium, as part of the
Roman Imperial cult. The creation of the new city of Philippopolis, piled on top of the massive tribute owed to the Persians, as well as the necessary
donativum to the army to secure its acceptance of his accession, made Philip desperately short of money. To pay for it, he ruthlessly increased levels of taxation, while at the same time he ceased paying subsidies to the tribes north of the
Danube that were vital for keeping the peace on the frontiers. Both decisions would have significant impacts upon the empire and his reign.
At the frontiers of the Roman Empire In 245, Philip was forced to leave Rome as the stability established by Timesitheus was undone by a combination of his death, Gordian's defeat in the east and Philip's decision to cease paying the subsidies. The
Carpi moved through
Dacia, crossed the
Danube and emerged in
Moesia where they threatened the
Balkans. Establishing his headquarters in
Philippopolis in
Thrace, he pushed the Carpi across the Danube and chased them back into Dacia, so that by the summer of 246, he claimed victory against them, along with the title "Carpicus Maximus". In the meantime, the
Arsacids of Armenia refused to acknowledge the authority of the Persian king Shapur I, and war with Persia flared up again by 245.
Ludi Saeculares Nevertheless, Philip was back in Rome by August 247, where he poured more money into the most momentous event of his reign – the
Ludi Saeculares, which coincided with the one thousandth anniversary of the foundation of Rome. So in April 248 AD (April 1001
A.U.C.), Philip had the honor of leading the celebrations of the one thousandth birthday of Rome, which according to the empire's official
Varronian chronology was
founded on 21 April 753 BC by
Romulus. Commemorative coins, such as the one illustrated at left, were issued in large numbers and, according to contemporary accounts, the festivities were magnificent and included spectacular games,
ludi saeculares, and theatrical presentations throughout the city. In the
Colosseum, in what had been originally prepared for Gordian III's planned
Roman triumph over the Persians, more than 1,000
gladiators were killed along with hundreds of exotic animals including hippos, leopards, lions, giraffes, and one rhinoceros. The events were also celebrated in literature, with several publications, including
Asinius Quadratus'
History of a Thousand Years, specially prepared for the anniversary. At the same time, Philip elevated his son to the rank of co-
augustus. ==Downfall==
