This paper aims to study the impact of the “migrant crisis” in 2015 and 2016 on German and Polish security. The article is divided into three parts. The first presents the causes and the evolution of the “migrant crisis” in the European Union. The second part compares previous migration experiences of Germany and Poland. The third part examines the state security implications of the last “crisis”. According to the author, the real impact of the migration processes on the state security is largely determined by the capacity of a government to deal with the changes that occur.
