Postal service is established between Boston and New York City.

The mail is delivered by a rider who left New York City on January 22, 1673 and traveled along the Upper Road through New Haven, Hartford, and Springfield. The monthly service is established by New York Governor Francis Lovelace, after being instructed by King Charles II that “his American subjects to enter into a close correspondency with each other.” The service is suspended first when the Dutch retake New York City later in the year, then by King Philip’s War. It resumes in 1685, becomes weekly in 1711, three times a week in 1814, and daily in 1880.
