When Florida became an American territory in 1821, almost no means of communication existed between its settlements or with other parts of the country. If a viable government and a prosperous economy were to be instituted, effective links of correspondence would have to be developed. To accomplish these ends, the post office department in succeeding years authorized many post roads and post offices. By 1845, there were approximately fifty post offices, and 2,920 miles of post roads in Florida.
