Deletion of Riograndense Republic

Comment: I have to point out that the first three sources clearly fail  - and can't |verify existence or anything else due to this. The third, a report on the secessionist feeling in southern Brazil only mentions the Riograndense Republic in passing, and does nothing to establish the existence of such a state, just that some organisations in the south exist who want secession
