Input: Charleston, South Carolina
By 1840, the Market Hall and Sheds, where fresh meat and produce were brought daily, became a hub of commercial activity. The slave trade also depended on the port of Charleston, where ships could be unloaded and the slaves bought and sold. The legal importation of African slaves had ended in 1808, although smuggling was significant. However, the domestic trade was booming. More than one million slaves were transported from the Upper South to the Deep South in the antebellum years, as cotton plantations were widely developed through what became known as the Black Belt. Many slaves were transported in the coastwise slave trade, with slave ships stopping at ports such as Charleston.

Input: Law of the United States
Federal law originates with the Constitution, which gives Congress the power to enact statutes for certain limited purposes like regulating interstate commerce. The United States Code is the official compilation and codification of the general and permanent federal statutes. Many statutes give executive branch agencies the power to create regulations, which are published in the Federal Register and codified into the Code of Federal Regulations. Regulations generally also carry the force of law under the Chevron doctrine. Many lawsuits turn on the meaning of a federal statute or regulation, and judicial interpretations of such meaning carry legal force under the principle of stare decisis.

Where are the regulations from executive branch agencies found?
Output: the Code of Federal Regulations
