The drive for globalisation has contributed to the emergence of global citizens who must work together and stand as one. Citizens who are a part of this globalisation process are not just citizens; rather, they are global citizens who have contributed to the world's various cultures coming together and seeming as one huge family. Despite the fact that the globalisation movement became more visible in the 1990s, the idea of global citizenship has existed in various forms since ancient times and may be found throughout history. With the advancement of technology and economic development there exist a paradoxical pattern that the world is diverse yet closely knit. One has to understand and behave in a socially just manner while dealing with a multi-diverse world or population. Justice is a basic requirement of life similar to the air we breathe, an essential element for living. Pre-service teachers play a pivotal role in shaping the future of students as they progress through the education system which becomes the bedrock for instilling values. It is therefore essential for pre-service teachers to be familiar with global citizenship and social justice.
