Question

i have to summarize what that means for a history paper... and im not entirely sure what it means

Answer 1

And you are answering this question in Olde English???

We Y/Aers aren't sure what you mean.  Chefe ilands?   Is your question about the meaning of an act declaring that certain island in the bay of Mexico are under the jurisdiction of the Spanish crown?  What year?  Now  (which would be a truly interesting question...)?
