Rome exercises stronger influence on the Getae as decades pass.

Roman merchants arrive to exchange goods, and the Getae begin counterfeiting Roman coins.

In the middle of the first century BCE, the Romans ally with the Getae to defend Moesia, an imperial province roughly corresponding to present-day northern Bulgaria, against the Sarmatians, a group of nomadic Central Asian tribes.

Roman engineers and architects help the Getae construct fortresses until the Romans discover that the Getae are preparing to turn against them.

Burebista, a Getian king who amasses formidable military power, routs the Celts, forces them westward into Pannonia, and leads large armies to raid Roman lands south of the Danube, including Thrace, Macedonia, and Illyria.

Burebista offers the Roman general, Pompey, support in his struggle against Julius Caesar.

Caesar apparently planned to invade Getian territory before his assassination in 44 BCE; in the same year Getian conspirators murder Burebista and divide up his kingdom.

For a time Getian power wanes, and Emperor Octavian expels the Getae from the lands south of the Danube.

The Getae continue, however, to interfere in Roman affairs, and the Romans in turn periodically launch punitive campaigns against them.
