Why was the US Postal Service created?

Making sure that the mail was delivered as quickly and dependably as possible was critical to the colonies' survival. That's why three months after the battles of Lexington and Concord, the Continental Congress turned to Benjamin Franklin to establish a national post service as the first Postmaster General.

An efficient postal service, in addition to promoting national cohesion, provides an essential infrastructure for the expansion of industry and commerce. Postal money transfer and savings services are particularly valuable in developing economies, where banking facilities are limited.
