[12:22.97]The last reading.
[12:25.79]Border
[12:27.66]A border is a real or artificial line that separates geographic areas.
[12:34.47]Borders are political boundaries.
[12:37.00]They separate countries, states, provinces, counties, cities, and towns.
[12:44.17]A border outlines the area that a particular governing body controls.
[12:50.16]The government of a region can only create and enforce laws within its borders.
[12:56.16]Borders change over time.
[12:59.25]Sometimes the people in one region take over another area through violence
[13:04.52]and other times land is traded or sold peacefully.
[13:09.14]Many times, land is parceled out after a war through international agreements.
[13:15.74]Borders-particularly national borders-affect travel and migration.
[13:21.76]People can usually move freely within their own country's borders,
[13:26.70]but may not be allowed to cross into a neighboring country.
[13:30.91]When neighboring countries have similar wealth and political systems,
[13:35.38]their borders may be open and undefended.
[13:38.63]For example, citizens of the 27-country European Union
[13:43.96]may travel freely among any of the member states.
