John Macdonell, 1911 Encyclopædia Britannica (1911)
“ Rather we may say with Maine, “Sovereignty is divisible, but independence is not.” To hold sovereignty not to be divisible is for juridical purposes not a working theory; states part, permanently or temporarily, with few or many of the rights and powers comprehended in sovereignty; to speak of it as undivided in the case of Crete, Egypt or Tibet is to do violence to facts. A frequent deduction from the theory of the indivisibility of sovereignty is that there cannot be double allegiance; in other words, no one can be the subject of two states. ”
