The Latifunida conquered new lands and began running large farms with the help of slaves, driving small farmers into bankruptcy and bankruptcy. This caused cracks in Rome's economic system. The area of ​​the Roman Empire was huge and there was not enough money to cover all the borders and pay the military. Taxes began to increase and people refused to pay high taxes, leaving cracks in our military and the maintenance of public buildings. Finally, in its heyday Rome had more than a million people living in its cities due to unemployment and they all took care of bread and circuses (welfare). The decline of the Roman Empire was therefore based on ten theories: invasion of barbarians, environmental impact, excessive military spending, inferior technology, inflation, political corruption, rise of Christianity, unemployment and urbanization.
