Jews homes were broken into and ransacked, Jewish businesses and synagogues were burned down, and family members were separated to be sent off to camps and or killed.
The Nazis forced the Jews to wear stars to show they were Jewish, forced them into only Jew ghettos, gave them very little food, and told stories about Jews, saying that they were terrible and greedy people, to make sure the Germans wouldn't help them. Many fell sick and died from the amount of people there and how weak they were.
The Jews that were sent to concentration camps were separated by age and gender, forced to work, starved, and killed in gas chambers. Over six million Jews were killed in the Holocaust.
People resisted by running away and emigrating to other countries. They had to travel through forests and or oceans, sometimes alone, and often had to leave most of their belongings and family members behind. They fled to countries like the US and Britain, or groups set up camps in the forests.
People resisted by joining the army and coming back to Germany to fight, or they would fight back in the concentration camps, sometimes gathering enough people to fight, or destroying the camps.
People also resisted by sending their children to summer camps or non-Jew families so that they could either stay at the camp or be adopted by the families until the Nazis lose the war. They also hid in friends homes or in not well known areas, like the Secret Annex in The Diary of Anne Frank.
