Why is "Slavery on the Barbary Coast" trending?

Wikipedia Overview

The Barbary slave trade involved the capture of an estimated 1.25 million Europeans and 700 Americans, then selling them at slave markets in the largely independent Ottoman Barbary states of North Africa during the early modern period. European civilians and American merchant seamen were captured by Barbary corsairs in slave raids on ships and by raids on coastal towns from Italy to Ireland, coasts of Spain and Portugal, as far north as Iceland and into the Eastern Mediterranean. Yearly, 20% of the US Federal Purse was given to the pirates for release of and to stop the enslavement of Americans. With frustration of Americans growing over the large amount of money given yearly to the pirates and capture of US Seamen, George Washington pled to Congress for the formation of the US Navy to stop them. In 1815 under American President James Madison, the US Marines and US Navy won the First Barbary War, stopping the capturing and enslavement of Americans. This historic war is referenced under the US Marine Corps Hymn as follows, “From the Halls of Montezuma, to the shores of Tripoli”.
