World Order is a necessity in modern day society, for if it did not exist we would be faced with international anarchy. A nation state acts individually, therefore meaning that it can either choose to embrace Human Rights and international laws, or ignore them.
World Order is known as being the creation of global relationships and maintenance of world peace. It also governs the relationships between nation states and other global participants.
World Order exists so that world conflict and global destruction doesn’t. Not only this, but World Order works through relations between countries, meaning that no nation state will stand alone, hence global issues such as global warming can be addressed more easily. It also serves as the backbone of economic interdependence as well as globalization.
In the early modern era, several monarchs, by weakening the feudal nobles and allying themselves with the emerging commercial classes, began to consolidate power. Kings and queens tried to bring all of the people they ruled over and all the territories they ruled over into one, unified body (beforehand, even villages would not have anything to do with each other). This however, was a difficult process and sometimes required violence, as well as taking a long time. This birth of a nation-state also lead to the first signs of nationalism, due to monarchs encouraging their subjects to feel loyalty towards the newly established nations.
Nation states (being the country) have sovereignty, which means that they have the right to make all the laws within the territories they govern, but also allows them to make treaties with other states and these treaties are the primary source of international law. State sovereignty is the states exclusive right to make laws for its own people without interference from outside countries. It is defined by having : defined borders (geographical area), a permanent population and the ability to form a government and engage in international relations.
