Law 19th Century North America

Congress Bans Importation of Slaves

By the early 1800s, the international slave trade had supplied labor for expanding Southern plantations despite growing moral and political opposition. The U.S. Constitution had deferred any ban on importation until 1808, giving Congress time to act. President Thomas Jefferson urged legislation in his 1806 message, and after debate the bill passed both houses. On March 2, 1807, Jefferson signed the Act Prohibiting Importation of Slaves into law, making it effective January 1, 1808. The statute criminalized bringing enslaved people into U.S. ports from abroad, imposed fines and forfeiture, and regulated coastwise trade to prevent evasion. It represented the first major federal restriction on the trade but left domestic slavery and interstate commerce untouched.

Law 19th Century Europe

Britain Abolishes the Slave Trade with Royal Assent

After decades of campaigning led by William Wilberforce and allies in Parliament, the Slave Trade Act reached its final stages in early 1807. The bill, prohibiting British subjects from participating in the Atlantic slave trade, passed the Commons overwhelmingly and received royal assent from King George III on March 25. It took effect May 1 but did not immediately free existing slaves in British colonies. The legislation empowered the Royal Navy to enforce the ban and pressured other nations to follow suit over subsequent decades.

Fulton's Clermont Begins First Commercial Steamboat Service

In the early 19th century, American inventor Robert Fulton partnered with Robert Livingston to develop practical steam-powered navigation on rivers. After years of experimentation in Europe and the United States, Fulton constructed the North River Steamboat, later known as the Clermont, with a Boulton and Watt engine driving paddlewheels. On August 17, 1807, the vessel departed New York City carrying paying passengers on its maiden voyage up the Hudson River toward Albany, covering about 150 miles in roughly 32 hours at an average speed of five miles per hour. The successful round-trip demonstrated reliable commercial viability despite initial skepticism from observers who doubted steam technology. This journey established scheduled passenger and freight service between the two cities within weeks.
