Borderlands Borders and Global Frontiers

At first glance the concept of borders, borderlands, or frontiers would seem to be straightforward. A border or boundary is a line on a map delineating a territorial boundary or the limit of a political jurisdiction. Borders are primarily, but far from exclusively, seen as properties of and under the control of states. Nevertheless, this has generally not always been the case. Even in the contemporary world where such an interpretation often does apply, the concept of borders frequently becomes much more complicated.
