Jews in our timeline lived distributed in Europe in different pockets where they engaged in various traditional occupations,in Europe. What if in this timeline,there was a Jewish Kingdom in Europe that became a modern nation and the Jews,instead of being spread over in different parts of Europe as minorities,live in one Nation as a majority? Smaller communities of Jews would exist in other countries but too small in this timeline and mostly integrated into the majority peoples of the particular country. How would this affect the various economic and cultural aspects in Europe? How would Germany,Poland,Russia,Ukraine look like in this timeline as these are the countries that had the largest Jewish minorities? How would WW2 go about? How would the alternate Business communities look like in these countries? How would the Jewish nation look like,socially and economically and how would it's relations with others be? How would this in modern era be like?
