The Carolina Constitutions
It has been some time since my last post, so it might help to skim over the previous post before continuing with this one.
The Carolina Constitution of 1669 came out four years after the Concessions and Agreements of the Proprietors of East New Jersey. Undoubtedly, Shaftesbury and Locke were acquainted with it. But when Berkeley and Carteret became the first proprietors of New Jersey in 1664, they probably studied the first Carolina Constitution of 1663 before publishing their Concessions and Agreements. Berkeley and Carteret knew what was happening in Carolina because they were among the eight Lords Proprietors of the colony, so we can assume there was a lot of cross-pollination.
