Globalization is a process that 'undermines the hitherto established model of the nation state and the welfare state in particular'. When people talk about globalization, they are usually thinking of processes and events and movements that spill over and cross national borders. The term refers to movement, diffusion, expansion, from a local level and with local implications, to levels and implications that are worldwide, or at least region-wide. In the period since World War II, there has been an important movement to globalize human rights, that is, to develop, proclaim, publicize and enforce standards of human rights. If there is a globalized world, if business and trade are globalized, and if there is a globalized culture of production and consumption, then it follows that there must also be a globalized sector of law. In the modern world, or at least in the developed world, legal systems have increased in scale and scope in recent decades.
