At the beginning of our era the Roman Empire was getting closer in its expansion to the Danube , and the Geto-Dacians could do nothing but have relations with it, now cordial, now hostile. They will resist the Romans both politically and military, for about century until the reign of the Roman emperor Trojan, who, after long and dreadful years of wars, succeeded in 106 A.D. to break the heroic resistance of the Dacians, whose king, Decebal - entered in legend for his bravery - committed suicide to avoid being captured. The resistance and partial destruction of Decebal' Dacia ( 14 %) has not changed in any way the basic structure of native people. As a mater of fact Dacia was the last territory conquered by the roman in Europe and the first left by them. The memorial monuments - Trojan’s Column (Rome) and Tropaeum Trojan (Adamclisi, Dobrogea (Dobrudja)) - attest through their celebrated scenes to the Dacians' bravery in defending their plains, fields, rich and well-sheltering mountains.
Besides all, Dacia never has suffered a process of integration into the Roman Empire, because 86 % of its territory was never occupied by them. Not to forget that , at the time of Roman Empire arrival Dacia already have reached a high level of material and spiritual culture and in 165 years of roman occupation of 14% of its territory practical was impossible to undergo a process of Romanization. As the Geto-Dacians has been the basic ethnic element in the making of the European people (see Noah'flood- W.Ryan & W. Pitman-" the Diaspora" pp 188-201), they were also the strongest element of the Romans' ethno genesis, which left lasting marks, traceable to the day, in the Italian people's Latin language, in its name, conscience and culture.
The crisis occurring in the Roman Empire as well as the pressure of the free Dacian people and other “barbarians” forced Emperor Aurelian to decide in 271 A.D. the withdrawal of the Roman troops, administration and a part of the urban population from The small portion (18%) of Dacia’s territory occupied by them, and moving south of the Danube. One more time the dacian population has been again together they will continue to exist generally speaking divided in three regions known as Transylvania, and Walachia.
Later some of the greatest Dacian Empire territory got re-unified under the name of what we call today Romania.
