A major provision of these treaties is the recognition of sovereignty.
The British are concerned that rulers of the weaker gulf families will yield some of their territory under pressure from more powerful groups, such as the Al Saud or the Ottomans.
Accordingly, the treaties signed between 1820 and 1916 recognize the sovereignty of these rulers within certain borders and specify that these borders cannot be changed without British consent.
