On macOS, I would recommend using aliases to create links like this; they'll allow you to use "habsburgs" as if it were a link to "the habsburgs". After renaming the page to "habsburgs", the "habsburgs" parts of your old links will still work are direct you to the page.
Aliases also allow you to link to a page called "habsburgs" with the text "the house of habsburg", or link to a page called "the house of habsburg" with the text "habsburgs"! They can be quite useful if you find yourself renaming pages and not wanting to change every link to that page.
Note that there is currently no equivalent for this functionality on VoodooPad for iOS.
