The correct answer is D.
When the Western Roman empire fell in 476, new civilizations occupied its former territories. These civilizations were mainly Germanic barbarians (term that the Romans had used to refer to non-Romans who live in the Northern European lands). These barbarians were mainly fierce warriors, not interested and not qualified for the organization of state powers, the enactment of law codes or the organization of a bureaucratic structures. Therefore, the end of the Roman Empire was for centuries the end of an organized type of state in its former territories.
