Joespaniel, You have all answers right, except the second. I didn't imagine it was so difficult.
2) Henry IV was excommunicated by Pope Gregory VII "through the power he received from the Apostle and Christ himself" . Note that the bishops who supported him were excommunicated as well. Henry was thus officially incapable of governing, go to church, have funerals or receive any other sacrements. Accused by its partisans of tyrannic cruaulty, Gergory VII had to give his pardon to Henry. After that, Henry IV continued his struggle against the pope, was excommunicated a second time, took Rome and elected an anti-Pope (Clement III) who crowned Henry emperor again
. Pope Gregory VII escaped in the Normand ruled South of Italy, where he later died.
5) the German Laender are the following : Niedersachsen, Sachsen-Anhalt, Sachsen, Thueringe, Schlewig-Holstein, Mecklemburg-Vorpommern, Brandenburg, Hesse, Rheinland-Westfallen, Rheinland-Pfalz, Saarland, Baden-Wuertenberg, Bayern, Berlin, Hamburg and Bremen. So 16 alltogether. Hamburg and Bremen might disappear soon to join Niedersachsen, I have heard. They are city-state originating from the Middle-ages Hanse Staedte (part of the Baltic Hanse, which was a commercial confederation of cities of Scandinavia, the Baltic and Northern Germany and Poland). So, nowadays their proud to be indepenant city-state are somewhat old-fashioned. It's like if Florence or Venice asked a city-sate status in modern Italy.
Nobody got the 5 answers right, so I ask another, easier, question :
When did the second Reich start and by which treaty ?
