The constant expansion of the Roman Empire did not spare Dacia (modern Romania) from being on the Roman occupation agenda even before the days of Caesar. Domitian tried in 89 AD to take over Dacia, but it seems that he ended up with a peace and alliance treaty.
The first Dacian War (101-102 AD) that Trajan led against the Dacians brought an important victory, so the Romans were ready to secure the new territories.
