International borders are defined by geographical features or legal jurisdictions. These borders separate one country from another and crossing these borders requires permission from the country where you seek entry. Many of these international borders are famous (and thus have been named) because of reasons including wars and disputes. While countries in European Union allow free movement among member countries, international borders between countries like South Korea and North Korea are virtually sealed.

Today, we will have a look at some of the major international borders in India and the world.
