List of national legal systems
Common law is currently in practice in Ireland, most of the United Kingdom (England and Wales and Northern Ireland), Australia, New Zealand, Bangladesh, India (excluding Goa), Pakistan, South Africa, Canada (excluding Quebec), Hong Kong, the United States (on a state level excluding Louisiana), and many other places. In addition to these countries, several others have adapted the common law system into a mixed system. For example, Nigeria operates largely on a common law system, but incorporates religious law.
World government
World War II (1939–1945) resulted in an unprecedented scale of destruction of lives (over 60 million dead, most of them civilians), and the use of weapons of mass destruction. Some of the acts committed against civilians during the war were on such a massive scale of savagery, they came to be widely considered as crimes against humanity itself. As the war's conclusion drew near, many shocked voices called for the establishment of institutions able to permanently prevent deadly international conflicts. This led to the founding of the United Nations in 1945, which adopted the Universal Declaration of Human Rights in 1948. Many, however, felt that the UN, essentially a forum for discussion and coordination between sovereign governments, was insufficiently empowered for the task. A number of prominent persons, such as Albert Einstein, Winston Churchill, Bertrand Russell and Mohandas K. Gandhi, called on governments to proceed further by taking gradual steps towards forming an effectual federal world government. The United Nations main goal is to work on international law, international security, economic development, human rights, social progress, and eventually world peace. The United Nations replaced the League of Nations in 1945, after World War II. Almost every internationally recognized country is in the U.N.; as it contains 193 member states out of the 196 total nations of the world. The United Nations gather regularly in order to solve big problems throughout the world. There are six official languages: Arabic, Chinese, English, French, Russian and Spanish. The United Nations is also financed by some of the wealthiest nations. The flag shows the Earth from a map that shows all of the populated continents.
