A border is a conventional line that marks the end of a State . Borders can be physically defined (with walls or fences ), although it does not always happen this way. That's why we talk about convention: the different countries agree as far as their respective limits reach; when passing this limit (the border), it enters the territory of the neighboring country.
The border, therefore, marks a sovereignty . He government of a country has authority within the limits of its borders. What happens beyond, even a few meters away, is beyond your business, as long as it does not affect your national interests.
The borders can be terrestrial, although there are also maritime, river, lake and even air borders.
Also when talking about borders we also have to make clear that there is a wide typology of them. Thus, for example, in addition to those already mentioned, we can refer to what are the cultural, social or economic boundaries. The latter are those established taking into account financial issues.
However, we must not forget the existence of those known as natural borders, which, as the name implies, are those that separate territories through a geographical accident, whether it is a mountain, a valley or a river, for example.
Every border is usually monitored to prevent illegal entry of immigrants or prohibited products (such as drugs or contraband).
The border between U.S and Mexico For example, it is one of the most guarded in the world, as thousands of Mexican citizens try to enter the northern country in search of a better living condition, although, in many cases, they do not meet the legal requirements necessary to Enter the neighboring country.
Spain in this regard we must emphasize that it has a series of borders that periodically become news in the various media by the large number of people trying to skip them. We are referring to the three borders that it maintains with Morocco: in Melilla, in Ceuta and in Vélez de la Gomera.
And it is that many are the African inhabitants of that country who engineer all kinds of actions to be able to jump the metal fences that separate them from Spain with the clear objective of trying to find a better future outside their nation.
On the other hand, Border It is a car model manufactured by General Motors . According to market , you can buy a Opel Frontera , a Isuzu Frontera or a Holden Frontera .
In the same way we cannot ignore that in Spain there is a musical group called “La Frontera”. In the decade of the 80s was when said training was launched, led by Javier Andreu, which has since released almost twenty albums that have reported great successes through songs such as "Duel in the sun" , "Judas the Miserable," "The Limit" or "Drink to Remember You."
