The Schengen Agreement is a treaty signed in 1985 that allows free movement of people within 26 European countries. This agreement has become an essential part of the European Union`s freedom of movement policy, and it has simplified travel for millions of people throughout Europe.

The Schengen Agreement is named after the town of Schengen in Luxembourg, where it was signed. The treaty abolished internal borders in the participating countries, which means that citizens of any participating country can travel freely across other participating countries without having to go through border controls. Therefore, there are no passport or visa checks when crossing these borders.

The agreement has also established a common visa policy for the participating countries, which means that a person who is granted a visa by one Schengen country is permitted to travel freely throughout the other Schengen countries as well. This has made travel easier for tourists, students, and business professionals who need to travel across several European countries.

The Schengen Agreement has created a common database of information on visa holders, which is shared between the participating countries. This ensures that people who pose a security threat can be tracked and monitored effectively.

However, it`s important to note that the Schengen Agreement does not apply to all EU countries. Some countries, such as the UK and Ireland, have opted out of the agreement, while others, such as Romania and Bulgaria, are still in the process of joining.

In conclusion, the Schengen Agreement is a vital treaty that promotes freedom of movement and travel within the European Union. It has made travel easier and more convenient for millions of people, and it has set a standard for other countries to follow. Its success can be attributed to the cooperation and trust between the participating countries, and it continues to be an essential part of the EU`s integration process.
