the reign of Burebista, the dacians represented a threat for
the Roman Empire. Caesar himself intended a campaign against
the dacians. Between 85 and 86, the army of king Duras attacked
Moesia (a dacian place).
In 84, Domitian organized a battle against Dacia, but they were
defeated at Tapae by the army of king Diurpaneus Decebal. In
88 the roman defense continues and the dacians are defeated
at Tapae by king Domitian. After this battle, Decebal and Domitian
made peace and Dacia became costumer of Rome. That means that
they get money and arms from romans for the frontiers defeat.
After some time, Decebal violated the rules and continued opposing
the romans because the payment was to big. The romans considerated
this like a threat.
Economic crisis form Roman Empire provoked the finding of Dacia’s
richness. This was the cause of two wars.
In the first war, Trajan was the emperior of Rome and he wanted
to conquer Dacia. Then, the roman army attacked Dacia, the final
battle being at Tapae, again, where Decebal lost the peace and
he was forced to surrender in 102. Then they made peace, which
wasn’t very favorable for Dacia, so Decebal was preparing
for another war.
The cause of the second war was the violation of the peace.
After Trajan heard this he put Appolodor from Damasc to built
a bridge above the Danubius, for the war.
In 106 the romans passed the bridge and attacked Dacia. The
dacians repulsed the first attack, but the roman destroyed all
the water resources of the capital and then they ignited Dacia.
Decebal escaped and he preferred to kill himself.
At the end of these two wars, Dacia had been transformed into
a roman province.
