The Rosenstrasse Protest was like a big group of people standing outside a building and yelling, "Let our loved ones go!"
To explain it better, let's say that a long time ago in Germany, there was a group of people who didn't like the leader of their country, Adolf Hitler. This leader said that if a person had a Jewish grandparent, they were also Jewish, even if they didn't believe in it. He also said that these Jewish people were bad and had to be sent away to a special place called a concentration camp.
One day, the leader's army came and took away many of the Jewish husbands and wives from a street called Rosenstrasse. Their families were very upset and didn't know where their loved ones were being taken. So, some women (wives and mothers) who weren't Jewish themselves, went to Rosenstrasse and started protesting outside the building where the Jewish people were being held.
The women were very brave and stood there for days and days, even in the cold weather. They yelled, sang, and sometimes cried, asking for their loved ones to be released. They did this even though they were scared of getting in trouble with the leader's army.
Finally, after a week of the protest, the leader's army decided to release the Jewish people back to their families on Rosenstrasse. The brave women saved their loved ones!
This protest was important because it showed that even though the leader of the country was very powerful, people could still work together and stand up for what was right. The Rosenstrasse Protest is remembered even today as a symbol of hope and courage.
