franz ferninad assasanation- june 1914 he was killed in seri avo gabriello princip was the one who killed him he was part of a group put together specifically made to kill fernidad called the blackhand
they tried to kill him earlier by throwing a gernade in his car but he threw it out and it blew up the car behing him. the driver took wrong turn and drove past the assasin again and he shot ferninad and his wife. SPARK that IGNITIED the powderkeg. ethnic group never getting along well.
U.S. nuetrality. nuetrality-not involved in war non alliance international law 1-nuetral countries had right to trade a with a country in war, 2-country in war could stop and seize contraband on nuetral ships. germany blockaded by great brittian so german use u boats (submarines) had to send warning so u boats were like sitting ducks.
germany tried to mexico to start war with the U.S. and they would give mexico all there land back if they were to start war with us.
