Okay, kiddo, let me explain a little bit about Crimean-Nogai raids into East Slavic lands.
So, first of all, there are three groups of people we need to know about: the Crimean Tatars, the Nogai people, and the East Slavs. The Crimean Tatars and the Nogai people were two groups of nomadic tribes who lived in what is now modern-day Ukraine and Russia a very long time ago. They were both known for being fierce warriors and for living nomadic lifestyles, which means they didn't settle down in one place but instead moved around a lot.
Now, the East Slavs were the people who lived in the areas that the Crimean Tatars and the Nogai people would sometimes raid. These East Slavs lived in what is now modern-day Ukraine and parts of Russia, and they were known for being farmers and for living in small villages and towns.
So, what exactly are these raids that we're talking about? Well, a raid is when a group of warriors attack another group of people to steal things, like goods and supplies, and sometimes to take people captive. The Crimean Tatars and the Nogai people would often go on raids into East Slavic lands because they wanted to get these things for themselves.
These raids were a big problem for the East Slavs, who were just trying to live their lives and take care of their families. They would often have to flee their homes and hide in the forests to avoid being kidnapped or killed by the raiders. Sometimes, the East Slavs would try to fight back against the raiders, but often they were outnumbered and outmatched by the experienced and skilled warriors of the Crimean Tatars and the Nogai people.
In summary, the Crimean-Nogai raids into East Slavic lands were when nomadic tribes, known for being fierce warriors, attacked and stole things from settled farmers and villagers living in what is now modern-day Ukraine and parts of Russia. These raids were a big problem for the East Slavs and often caused them to flee their homes or hide in the forests to avoid being kidnapped or killed.
