There are so many forms of government. There were kings in Israel and Assyria, an emperor in Rome, and a democracy in Greece. There were also governors, satraps, judges, and prefects along with the Jewish Sanhedrin. Subsequent history has also seen the parliamentary form of government to limit the power of royalty in England, and the Republic which allows democracy in America. Communism has also risen in the Soviet Union, China, and elsewhere. In America the elected president has his power limited by the Congress that writes the laws and the Courts that oversee that all law is based on the Constitution.
Recognized by God. Yet, all forms of government though devised by men were both foreseen and ordained of God: “He has made from one blood every nation of men to dwell on all the face of the earth, and has determined their pre-appointed times and the boundaries of their dwellings, so that they should seek the Lord, in the hope that they might grope for Him and find Him.” (Acts 17:26-27). God knows their pre-appointed times (when they will start and when they will end). He also knows the boundaries of their habitations (how far their dominion will be observed). All of this works into God’s plan to use nations to lead as many as possible to grope for and find Him.
