This and the next chapters address, in an introductory manner, two fundamental questions that lie at the root of private international law and serve to understand its broad conceptual scope. Both questions are approached from the Colombian perspective, considering the current situation of the discipline in the country. The first question, which is dealt with here, is quite wide and refers to the role that private international law plays in today’s world. Thus, this chapter outlines what lies behind the national, international, and global dimensions of private international law, and also the relevance it has when it is particularly considered from the global perspective. The second question, on which the next chapter focuses, is not less vast and concerns the interactions between comparative law and private international law.
