The ancient Greeks actually lived in houses made of dried mud bricks. Unfortunately, their walls are not very strong. It was common for houses to be broken into pieces, and most had to be renovated. The roofs of the houses are covered with mud panels and the windows are small and covered with wooden shutters.
It was a trigger that showed that there were two competing powers in Europe: Russia and Austria-Hungary (and their allies).
Franz Ferdinand was killed by a Serbian separatist and the Austrians wanted to see him punished. On the other hand, Russia supported Serbia is saying that Austrian demands ( to be allowed to search for the culprit inside Serbia) were too much.
This lead to a direct conflict between the two powers (Austria and Russia) and further lead to the war.
