Chungcheong Byeongyeong was reinstalled from Hae-mito Cheongju in 1651.That was the total re-disposition of military camp to reinforce the defence of the main fortcity, and a plan to stabilize finance in Hoseo area. After the reinstall, the military organization of Chungcheong province was changed into 5 camps and 2 mountain fort systems. The number of soldiers was the smallest among the three southern provinces, but it had an important mission to defend province against a foreign enemy from the south. As the period ofpeace went on in Late Joseon Dynasty, the military function of Byeongyeong was diminished, and the function to keep the public peace got expanded. Actually Chungcheong Byeongyeong was positioned as an organization ofthe national system as it performed the missions for the public security like arresting thieves, management of the foreign ships from the western countries, catching tigers and arresting the catholics. The financial structure of Chungcheong Byeongyeong in late Joseon consisted of Gyeol-yeok, Shin-yeok, and the income of Hwan-gok, and the last one was the biggest source of income. As the rate of distribution of Hwan-gok became higher after the nineteenth century, the abuse like a Heoryugok came up. As this Hwangok became a real tax, the abuse of the government official was increased. As the abuse was increased, Chungcheong Byeongyeong enforced the installment of paying tax. But it was not effective and the pressure from this went to local people directly. When the peasant protest broke up in 1862, most of the protests in Chungcheong province occurred in the villages around Cheongju, it means that the financial running of Byeongyeong based on the military service and Hwan-gok was the cause of the break down of the local establishment systems because of the disrupted Sam-jeong, the three tax system.
