Moments in History: The First Time America Invaded Libya

"Those who do not learn from history are doomed to repeat it.”
The situation unraveling today between the United States and Libya is fluid at best, but a look back at our Libyan invasion in 1805 shows a president and Congress who authorized military activities without a war declaration.
The “shores of Tripoli” is best known as a verse in the Marine Corps anthem. Today, Tripoli is the larget city in Libya, with 2.2 million people.
Article I, Section 8, of the Constitution gives Congress the power to declare war. But it specifies little else in the process. The War of 1812 was the first one that saw a Declaration of War approved by Congress.
Prior to this 1812 declaration, three U.S. military actions were sanctioned by the president and Congress without a war declaration: the "quasi-war" with France, and two military campaigns in North Africa.
However, in 1805 Tripoli was literally a pirates’ den that was a huge thorn in the side of three U.S. presidents: George Washington, John Adams and Thomas Jefferson.
It would take actions started by Jefferson, and then later by James Madison, to send U.S. military forces to the region, without a Declaration of War from Congress. The legislature did approve the military actions by statute, in a manner similar to some recent U.S. actions.
