Campaigns fought by successive Roman emperors over territory corresponding roughly to modern Romania and part of Hungary. The Dacians threatened the lands south of the River Danube which Rome regarded as a natural frontier. Under Emperor Domitian peace was agreed and considerable financial aid given to the Dacians. Then Emperor Trajan stopped payments, crossed the Lower Danube, and fought two campaigns ad 101 and 105–6 that were commemorated on Trajan's column in Rome, which is still standing today. Dacia became a Roman province, until Emperor Aurelian abandoned it to the Goths in 270.
