| @exackerly: Your comment raises an excellent question effecting all the quizes of this type. I am sure there were a thousand variations of what rights were granted to colonizing powers and its citizens, but they clearly could be, and often were, pretty extensive.
Here is one example of how a trade treaty might grant substantial concessions to an outside power to the point whereby one could not reasonably say the granting country retained sovereign control over an area: http://en.wikipedia.org/wiki/Pactum_Warmundi (spoiler alert for the Venetian Empire quiz)
In this case, the "colonizing" power, Venice, was granted, for example, its "own church, street, square, baths, market, scales, mill, and oven in every city" of the granting power. In one city, it was "granted one-third of the city and one-third of the surrounding countryside" and "These privileges were entirely free from taxation". Citizens of Venice were subject to their own country's law and their estates sent back to Venice upon death rather than being colonized by the granting power's king. |
