House of Representatives must be aware of the interests within his or her district’s borders. Citizens within these borders often vote as a unit, based on shared political beliefs.
congressional districts protect ethnic, religious, or economic communities. In addition to North Korea, nations such as Myanmar and Cuba rarely allow their residents to cross their borders.īorders can also serve to protect resources. Most governments with these “closed borders” are not democratic. Sometimes, borders serve to keep citizens in. Cambodian and Thai military units are positioned along the border near Preah Vihear Temple, and skirmishes often result in deaths on both sides.
Cambodia and Thailand, for example, have disputed the territory of the Preah Vihear Temple for more than a century. This is especially true in areas where two or more countries have fought over the same land for many years. Countries protect their borders for several reasons. Most countries have some sort of military or law-enforcement presence along their borders. The United States issues “green cards”-officially known as permanent resident cards-that allow non-Americans to live and work inside the borders of the U.S. Visas and work permits are government documents issued to non- citizens that limit the type of work or travel they may do in the country, and for how long. North Koreans must also have official permission before they leave the secretive nation.Įvery country has its own rules about who may travel, work, and reside within its borders. Citizens of most countries must have a passport and official permission to enter the borders of North Korea. The zone, which is 4 kilometers (2.5 miles) wide and 243 kilometers (151 miles) long, separates the two countries with barbed-wire fences, land mines, and armed guards. On the opposite extreme, the Korean Demilitarized Zone-the border between communist North Korea and democratic South Korea-is the most heavily militarized border in the world. Only five EU members-Bulgaria, Cyprus, Ireland, Romania, and the United Kingdom-require travelers from other EU states to present a passport or ID card at the border. For example, citizens of the 27-country European Union may travel freely among any of the member states. When neighboring countries have similar wealth and political systems, their borders may be open and undefended. People can usually move freely within their own country’s borders, but may not be allowed to cross into a neighboring country. The borders of four countries divide Africa’s Lake Chad: Niger, Chad, Cameroon, and Nigeria.īorders-particularly national borders-affect travel and migration.
For part of its length, the boundary between the United States and Mexico follows a river called the Rio Grande. For example, the boundary between France and Spain follows the crest of the Pyrenees mountains. Sometimes, borders fall along natural boundaries like rivers or mountain ranges. Many times, land is parceled out after a war through international agreements. Other times, land is traded or sold peacefully. Sometimes the people in one region take over another area through violence. The government of a region can only create and enforce laws within its borders.īorders change over time. A border outlines the area that a particular governing body controls. They separate countries, states, provinces, counties, cities, and towns. A border is a real or artificial line that separates geographic areas.
