The Trent affair, which occurred during the early years of the U.S. CIVIL WAR, challenged the traditional concepts of freedom of the seas and the rights of neutrals and almost precipitated a war between the United States and Great Britain.

In England, however, news of the impending death of Prince Albert diverted attention from the Trent affair. When the English demands were received in the United States, Charles Francis Adams, U.S. diplomat to England, was ordered...
