The EU in the past year, 2016. suffered perhaps the biggest change since its creation. Although formed of shocks, many important things happened during the year. All those events threatened the survival of the community, conceived as a Union of equal people which would guarantee all peace and prosperity. The decision of theBritsh votersabout leaving the EU, terrorism, the lack of agreement on the subject of migrant crisis, the growth of euroskepticisim and the increasing influence of extreme right - wing pointed us in 2016. year. So many see as annus horribilis, but in economic terms it was not so bad for the EU, as the first signs of economic recovery started to show. But, nevertheless, Brexit inflicted the greatest blow to the image and attractiveness of the Union. If one of the most successful countries leaves the Union, that shows that the British people are extremely dissatisfied with the policy of the EU. The fear of uncontrolled immigration and loss of sovereignty were greater than the various warnings of economic hardships that await them if they opt for independence. The consequences of Brexit in Ireland, can be tougher in the UK because of their dependence on trade with Britain. Other then that, Benelux may be threathened by it while the impact on Germany was very limited, because their production activities have nomerous markets all over Europe. Brexit attracted the attention of milion of citizens, rather euroskeptics, throughout the Union which were left on the margins of society by globalization and who do not see any benefits from the British ethnic diversity and free market.
