'One Chief Letter Office at New-York': Packet Ships, Imperial Administration, and the Geography of the American Post, 1692-1783

The postal system in the American colonies is an understudied arm of the first British Empire. Although outside the main institutions of colonial administration, the post office followed the overall periodisation of imperial affairs, as America waxed and waned in London's attention. This directly shaped the geography of the post office, because American officials focused on the post's ability to connect American towns, while British officials emphasised the transatlantic connection of the postal packet ships. The packets, however, were not as important to transatlantic communications as they imagined, which led the American officials to resist when London wanted to make New York City the headquarters of the American post.
