Coming to nationhood late put Germany on a collision course with other established European nations and led in some ways to the turbulent period between 1870 and 1945. After the war Germany sort to rebuild and invested great amounts of money in its engineering and technology driven companies, it also tried relatively successfully to make amends for the blackest moments in European history The Holocaust with a huge amount of educational discussion in schools. Currently in Germany, denial of the Holocaust or that six million Jews were murdered in the Holocaust is a criminal act; violations can be punished with up to five years of prison. In 1991 the Berlin wall came down that separated East Berlin from West this also led to the reunification of Germany a successful project.
