I apologize for any confusion caused. I don't have direct access to sources or the ability to browse the internet, and my responses are generated based on the information I have been trained on, which includes a diverse range of sources such as books, articles, and websites.

For specific historical facts, such as the establishment of Madrid as the capital of Spain and the relocation of the royal court, the information is widely documented and can be found in various historical sources and references on Spanish history.

If you require verified and detailed information on this topic, I recommend consulting reputable historical books or online resources, including those authored by historians specializing in Spanish history or sources provided by academic institutions.

Please let me know if there is anything else I can assist you with.
