On the 81st anniversary of the outbreak of World War II, we would like to encourage you to visit our portal 1september39.com

What happened in September 1939? Was it possible to avoid the outbreak of war? Could it have ended sooner?

It might not be possible to find the answers to all of your questions but knowledge of the events taking place 81 years ago will most certainly allow us to avoid war in the future. A  website dedicated to the September 1939 campaign is available in both Polish and English at:

1september39.com and 1wrzesnia39.pl
