Why do you think Eastern Europe has been the site of so much warfare??

It is a border land between Russia, powerful since Peter the Great and France once a world power( later Germany, arguably the most powerful nation in the world by 1914.). As was the case with post Charlemagne Lotharingia the border lands are competed for by major powers. This constant competition fueld warfare from Roman times until relatively recently.

theres alot of ethnic and religious diversity, slavs croats, muslims, catholics, eastern orthodox

Unfortunate location. See map of Roman empire. http://images.google.com/imgres?imgurl=http://www.unrv.com/images/provinces.jpg&imgrefurl=http://www.unrv.com/roman-empire-map.php&h=545&w=900&sz=78&tbnid=0KmkZOsCdjfq-M:&tbnh=88&tbnw=146&prev=/images%3Fq%3Droman%2Bempire%2Bmap&start=1&sa=X&oi= images&ct=image&cd=1
What we now call eastern Europe was at the frontier and open to invasion from the stepps. Then they were in the contested area between Christian Europe and the Moslem and Ottoman Empire. see map at http://ccat.sas.upenn.edu/~rs143/map6.jpg In more recent times the their history has left them with a devided culture so building a unified nation has proved immposible.


My answer does not apply to Poland, but Poland has not been the site of excessive warfare by Europran standards. Being between Russia and Germany in the 20th century was unfortunate to say the least.
