In the alliance protocol signed by Russia, Austria and Thorpe, the code of conduct of the participating countries of the alliance is stipulated. Only on the premise of taking the Christian doctrine as the theoretical basis, the behavior of the state is legal. The so-called Christian doctrine actually refers to taking the spirit of the Bible as a guide for their actions: "According to the Bible, all people should treat each other as brothers, and the three contracting monarchs will unite with each other with sincere and inseparable brotherhood, treat each other as compatriots in the same country, and help each other whenever and wherever."
In order to better implement the spirit of the Three Kingdoms in the holy alliance Agreement, Russia, Austria, Sweden and Britain signed an agreement after the unanimous decision of the heads of the three countries, which is called the "Four-nation Alliance" in history. In this agreement, it is stipulated that either side of the four countries has the obligation to send troops to help when the other side is attacked. Dramatically, in the second year, France even joined this alliance agreement, which was originally intended to prevent its attack, so that the four-nation agreement changed from four countries to five countries, with the same purpose. Thus, the "Four-Nation Alliance" is actually the continuation and development of the "Holy Alliance", both of which are aimed at suppressing all revolutionary movements and maintaining the existing international order.
18 15 after France joined the four-nation alliance, in order to better unite all countries in the world to suppress the rising domestic uprising, in the same year, 1 19, King Louis Stanislas Xavier of France joined the Holy Alliance. With the growing voice of countries around the world against feudal monarchy, revolutionary movements represented by the bourgeoisie broke out in France, Russia and Germany. This form made monarchs of various countries try to suppress domestic revolutionary movements with the help of other countries in the holy alliance, so more and more countries joined the holy alliance. In the end, all countries in the whole European continent except the British Regent, the Ottoman Sultan and the Pope joined.
Russia has played the role of "leader" in the holy alliance, and the allied forces under its leadership have been playing the role of strangler of the European revolution under the guise of safeguarding justice, love and peace of Jesus. As Engels commented, holy alliance is "a conspiracy of all European monarchs against their own people under the leadership of the Russian czar".
