Dear Readers, I am very pleased to present you the 45th volume of the Polish Political Science Yearbook (2016). From the beginning, the journal was connected with the Polish Association of Political Science (established in 1957) and in fact, played a role in its organ. At first, the periodical was published under the title Polish Round Table, and then the name was changed into the current one. The fundamental aims of the Polish Political Science Yearbook for the last 45 years and even earlier have not changed. The authors have made an effort to maintain and even increase the quality of publishing papers. These aims were and are the priority tasks. In the near future the deepened emphasis will be directed towards theoretical and methodological background of every paper. The PPSY will be more open for scientific discourse on various vital challenges and threats of contemporary political science in Poland and in the World.
