Tripoli.
When America refused to pay a bribe to the Barbary States in the early 19th century, particularly to Tripoli, it led to the First Barbary War (1801-1805). The ruler of Tripoli, Pasha Yusuf Karamanli, declared war on the United States in response to this refusal. The conflict arose from ongoing tensions over piracy and the demands for tribute from American merchant ships in the Mediterranean.
