Hello! Welcome to Wikipedia, and thank you for your contributions. At least one of your edits, while it may have been in good faith, was difficult to distinguish from vandalism. To help other editors understand the reason for the changes, you can use an edit summary for your contributions. You can also take a look at the welcome page to learn more about contributing to this encyclopedia. For example, you replaced "Ottomans" with "Muslims" without adding any sources or explanation in Slavery in Sudan or deleting "utopian" from "utopian socialism" at Figuerism. Many of your edits have been reversed — please do not make substantive changes to wording without explaining in the edit summaries why they are necessary.
