This is a list of selected July 21 anniversaries that appear in the "On this day" section of the Main Page. To suggest a new item, in most cases, you can be bold and edit this page. Before doing so, please review the selected anniversaries guidelines. If your suggestion is potentially controversial or relates to a day currently or soon to appear on the Main Page, post it on the talk page instead.
Please note:
- Events listed on the Main Page are selected based on article quality and to provide a diverse range of topics, rather than solely on the importance or significance of the events.
- Only four or five events are featured each day; therefore, not all important or significant events can be included.
- An event is generally excluded if it is already the subject of the scheduled featured article or picture of the day.
