The European Union is an economic integration that has proved to be a global power on the way to becoming a regional power. Although it is generally accepted that this integration formation started after the second world war, in fact, the origins of integration have been endeavouring to become an integrated Europe since the first centuries after Christ, either in the form of states and empires through wars or religious acceptance. In fact, the process after the Second World War is not a beginning but the result of the integration imposed by history. In the first book of the series, important people and empires until the Enlightenment period, in the second book, the period from the Enlightenment period to the Second World War, and in the last book, we will try to clarify the contributions and discourses of important people in the phase from the Second World War to the present day. When the readers finish the series, they will see that behind the developing and global power established in just 50 years is the spirit of the United European State, which comes from history and is constantly kept alive.
