Can you explain me the difference betwen border and frontier ?
Thank you a lot
A border is boundary line established by a state, or a region, to define its spatial extent, but a frontir is the part of a country which lies on the limit of the settled area. Frontier differs from a border because the term frontier indicates outward expansion into an area previously unsettled by a particular state. Some frontiers have occurred where two nations advance from different directions, leading to boundary disputes. A settlement frontier marks the furthest advance of settlement within a state while the political frontier is where the limit of the state coincides with the limit of settlement.
Hope this helps
