Okay kiddo, so imagine you and your friends are playing a game, but one of your friends keeps changing the rules to give themselves an advantage. That's not fair, right? Well, something similar happened a long time ago when America was becoming a country.
There were some people who wanted to make sure that the new Constitution, which is like the rules for the whole country, protected individual rights and freedoms. But some other people didn't think that was necessary. These two groups had a big argument about it, and they almost didn't agree on anything.
Then, a guy named James Tallmadge came up with an idea. He said that slavery was really bad and it shouldn't be allowed in any new territories that might become states in the future. This idea was called the Tallmadge Amendment.
Now, some people didn't like that idea either, because they owned slaves and they didn't want to give them up. But some other people thought it was a good way to make sure that the country didn't become too divided over the issue of slavery.
In the end, the Tallmadge Amendment didn't get approved, but it showed that people were still trying to figure out how to make the country fair for everyone. And eventually, the issue of slavery would become so important that it would lead to a big war, but that's a story for another day.
