The document summarizes the major consequences of World War 1 across political, economic, social, colonial, and international realms. Politically, four major European empires collapsed while new countries emerged from partitioned territories. Economically, Europe lost its global supremacy as the US benefited and took the lead. Socially, traditional norms were challenged and women gained new rights and roles. The League of Nations was formed to promote cooperation but lacked power without the US and defeated nations. Overall, the post-war treaties set the stage for renewed tensions in Europe.
