The decision to leave the European Union membership as a result of the referendum held in the UK in 2016 caused shock in many countries, especially in EU member states. Since its establishment, for the first time, a country voluntarily wanted to leave the EU membership.
The EU, which had been waiting Turkey, which applied for full membership at its door since 1987 had deteriorated. The EU values that were being tried to be created were in danger. But I think for the first time in the member states of the EU, the current structure and decision-making processes of the EU began to be put on trial.
The United Kingdom, which defines itself as the cradle of democracy complained a lot about foreign immigrants and wanted the EU to take drastic measures in this regard. In fact, the legislation was more suitable for the citizens of the former "Commonwealth" member countries to settle in the UK. While millions of British people were already angry with the Polish, Romanian, Bulgarian and Greek citizens who took their jobs by taking advantage of the principle of "free movement of labor", they were also trying to deal with refugees from countries such as Afghanistan, Iraq and Syria, which were experiencing civil war.
Meanwhile, the rapid growth of countries such as Russia and Turkey against the main block that formed the European Union further increased the tension in the country. When currents such as racism and Islamophobia were added to this, the opposition winds pushed the EU supporters in the country to a minority position.
