Germanic tribes questions

The Germanic peoples were organized in [blank_start]tribes[blank_end] and lived in the [blank_start]north[blank_end] and [blank_start]east[blank_end] of [blank_start]Europe[blank_end]. They [blank_start]traded[blank_end] with the Romans, [blank_start]joined[blank_end] the Roman [blank_start]army[blank_end] or held [blank_start]properties[blank_end] inside the empire. But, when the Roman Empire suffered an [blank_start]economic[blank_end] and [blank_start]social[blank_end] crisis in the [blank_start]third[blank_end] century AD, the Germanic tribes began to [blank_start]raid[blank_end] the Roman [blank_start]towns[blank_end].

To better defend from the [blank_start]attacks[blank_end], emperor [blank_start]Theodosius[blank_end] divided in [blank_start]395[blank_end] AD the Roman Empire into two: the [blank_start]Western[blank_end] Roman Empire whose capital was [blank_start]Rome[blank_end] and the [blank_start]Eastern[blank_end] Roman Empire, whose capital was [blank_start]Constantinople[blank_end].

The Huns, a people of [blank_start]nomadic[blank_end] [blank_start]herders[blank_end] who crossed the Asian steppes, attacked in the [blank_start]5th[blank_end] century the Romans and the Germanic tribes. These tribes [blank_start]entered[blank_end] the Roman Empire in search of greater [blank_start]security[blank_end]. The Huns, under the rule of Attila, advanced until they were defeated in the [blank_start]Catalaunian[blank_end] Plains.
