body: *Texas v. White* is generally regarded as the case that established that US states cannot unilaterally secede. The majority opinion stated that the union between Texas and the other States could not be dissolved:
  
  
  
  > 
  > . . . except through revolution or through consent of the States.
  > 
  > 
  > 
  
  
  How is "revolution" distinguished from secession and civil war? Did Chief Justice Chase ever elaborate on this, or did any other case ever examine this detail of the ruling? Is a "revolution" simply a militarily successful secession?
