Please refrain from making unconstructive edits to Wikipedia, as you did at Frederick the Great. Your edits appear to constitute vandalism and have been reverted. If you would like to experiment, please use your sandbox. Repeated vandalism may result in the loss of editing privileges. Thank you. -Bryan Rutherford (talk) 23:33, 9 September 2020 (UTC)
Your first edit changed text and replaced a reliable source ref (a newspaper) with a Youtube ref. Youtube is not considered a valid source for references because anyone can create content. For same reason, Wikipedia articles cannot use other Wikipedia articles as references. Your second edit entirely changed the meaning of a sentence. To do this, a valid ref is required.
