Answer:
assassination of Archduke Franz
Explanation:
Nationalist groups contributed to the weakening of the Ottoman Empire in eastern Europe, by seeking to throw off Muslim rule It was this pan-Slavic nationalism that inspired the assassination of Archduke Franz Ferdinand in Sarajevo in June 1914, an event that led directly to the outbreak of World War 1
Gutenburg's printing press was such an important invention, because before he invented it, people would either write stuff all by hand, or make some stamping system. If Gutenburg hadn't invented the printing press, we wouldn't have printers to print things out!
Extra:
Gutenburg designed the printing press in a town called Strasbourg, France. he built the actual thing in Mainz, Germany.
It might lower the population drastically.
Hope this helps!
