The Schengen Visa may be the best-known example of a common visa. This visa has it origins in the 1985 Schengen Agreement among European states which allows for a common policy on the temporary entry of persons (including visas). The schengen visa allows a tourist or visitor access to the area covered by the agreement (known as the "Schengen Area" or "Schengenland", currently consisting of 25 countries). Those who require a schengen visa to enter the Schengen area, are simply required to get only the common Schengen Visa from the Embassy/Consulate of any of the Schengen countries. After this, they may visit any or all of the Schengen countries as tourists or for business without hindrance. They are not required to get separate Schengen visas for all the Schengen countries they wish to visit. If an alien is visiting multiple countries in the Schengen zone, he typically applies in the embassy/consulate of his main destination country (i.e. where he plans to stay the longest).
The Schengen Agreement is an agreement between various countries in Europe to guarantee free movement of persons with/without a Schengen visa between countries. Signatory states to the agreement abolish all borders between countries in lieu of a single external border on the edge of the Schengen Area.
The Schengen Agreement was originally created independently of the European Union, in part owing to the lack of consensus amongst EU members, and in part because those ready to implement the idea did not wish to wait for others to be ready to join. The United Kingdom and Denmark did not join the union, but Denmark joined later when Norway and other Nordic countries were allowed.

The two agreements which are commonly referred to as Schengen Agreement are:
The 1985 Agreement between the Governments of the States of the Benelux Economic Union, the Federal Republic of Germany and the French Republic on the gradual abolition of checks at their common borders, also known as Schengen I, which provided for simple visual surveillance of private vehicles crossing the common border at reduced speed, without requiring such vehicles to stop. Persons who did not have to meet specific requirements at internal borders, as, for example, visa requirements, could use this fast lane procedure by affixing to the windscreen a green disc measuring at least eight centimetres in diameter.
The 1990 Convention implementing the Schengen Agreement of 14 June 1985 between the Governments of the States of the Benelux Economic Union, the Federal Republic of Germany and the French Republic on the gradual abolition of checks at their common borders, also known as Schengen II or CIS.Source: http://en.wikipedia.org/wiki/Schengen_Agreement
