Although in theory the equal field system was quite perfect it began to disintegrate in the 8th century. 3. The direct impact of the decrease of free peasants was a sharp diminuation in the tax revenue. 4. The burden of taxes on the population was quite high at the end of Tang, mainly because the central government had lost its grip on the different regions of the empire and because more and more land was purchased by large estate owners. 5. Emperor Xuanzong appointed some wicked chancellors who then corrupted the political order. 6. The Tang Military made the the dynasty powerful until the An Shi Rebellion which made the military weakened by the rebellion.
