Although the Schengen Agreement was signed in 1985, the genuine execution of the Schengen Area began on 26 March 1995, with 7 Schengen member nations: Belgium, France, Germany, Luxembourg, Netherlands, Portugal, and Spain chose to cancel their inner border checks.
From that point forward, the Schengen Area began a quick growth pattern. Joining the original 7 Schengen member countries on 28 April 1995 was Austria. Then on 19 December 1996, Denmark, Finland, Iceland, Norway, and Sweden were the new 5 nations to be part of the Schengen Agreement. Then again, drove by the example of seven previously mentioned nations, in October, Italy and in December 1997, Austria nullified their inward border controls.
Another real advance appeared for the Schengen Agreement, when in May 1999 "The Treaty of Amsterdam" joined the understanding inside the legitimate system of the European Union, as in the past the Schengen Agreement and tenets set by the agreement were separate from the European Union and were working independently.
The growth of the Schengen Area proceeded with its prosperous voyage as on January 2000, Greece and on March 2001, Denmark, Finland, Sweden, Iceland, Norway, on 16 April 2003 Czech Republic, Estonia, Hungary, Latvia, Lithuania, Malta, Poland, Slovakia and Slovenia and on October 2004 Switzerland were the new 15 that joined as part of the Schengen Agreement. This fruitful story did not end there, as on December 2007 the countries mentioned above, announced the abolishment of their land and ocean, and on March 2008 of the air terminal border controls.
On February 2008, Liechtenstein was the 26th and the last nation so far to consent to the Schengen Arrangement and grow to be a part of the Schengen Area.
