Check out Khanacademy.org under Arts and Humanities. All sorts of history content. Seems to be focused on the US, but there is international stuff there as well. All free.

Keep it up! There is so much to discover😊

I personally like Extra Credits. They started as a education gaming group and moved to a bunch of different topics one of which is Extra History. They talk about some very specific topics in an interesting way.

Check out the podcast Behind the Bastards, it's really cool and will teach you stuff you won't learn in school about really terrible people in history and the present day! I wouldn't recommend it for elementary aged kids but it's appropriate for teenagers (though some of Robert's references are a bit outdated for young people today).
