The Nazis tried to destroy Jewish life and culture - but Jewish people fought back in several ways
For example, secret schools, theatres and places of worship were set up in some ghettos
Also, some Jews violently rebelled against what was happening to them
In 1943, in the Warsaw ghetto in Poland, Jews rebelled against the German soldiers there
It took 43 days for the Germans to regain control
They then arrested and executed all those involved and burned down the ghetto
There were sometimes rebellions in death camps too
The best-known of all was in Treblinka in 1943
One of the prisoners managed to get into the weapons store when he handed out guns and grenades
After setting the camp on fire, 150 prisoners managed to escape, killing 15 guards in the process
However, the Nazis soon regained control and many escapees were killed
