A political boundary is an imaginary line separating one political unit, such as a country or state, from another. Sometimes these align with a natural geographic feature like a river to form a border or barrier between nations. Occasionally, two countries may contest where a particular border is drawn. These disputes might arise due to a natural resource both groups want, like in the case of Sudan and South Sudan, or in an attempt to gain more political power, as in the case of Pakistan and India in the Kashmir region.
