The USA Senate ratifies the Louisiana Purchase.

On this day in 1803, the U.S. Senate approves a treaty with France providing for the purchase of the territory of Louisiana, which would double the size of the United States.

At the end of 18th century, the Spanish technically owned Louisiana, the huge region west of the Mississippi that had once been claimed by France and named for its monarch, King Louis XIV. Despite Spanish ownership, American settlers in search of new land were already threatening to overrun the territory by the early 19th century. Recognizing it could not effectively maintain control of the region, Spain ceded Louisiana back to France in 1801, sparking intense anxieties in Washington, D.C. Under the leadership of Napoleon Bonaparte, France had become the most powerful nation in Europe, and unlike Spain, it had the military power and the ambition to establish a strong colony in Louisiana and keep out the Americans.

Realizing that it was essential that the U.S. at least maintain control of the mouth of the all-important Mississippi River, early in 1803 President Thomas Jefferson sent James Monroe to join the French foreign minister, Robert Livingston, in France to see if Napoleon might be persuaded to sell New Orleans and West Florida to the U.S. By that spring, the European situation had changed radically. Napoleon, who had previously envisioned creating a mighty new French empire in America, was now facing war with Great Britain. Rather than risk the strong possibility that Great Britain would quickly capture Louisiana and leave France with nothing, Napoleon decided to raise money for his war and simultaneously deny his enemy plum territory by offering to sell the entire territory to the U.S. for a mere $15 million. Flabbergasted, Monroe and Livingston decided that they couldn’t pass up such a golden opportunity, and they wisely overstepped the powers delegated to them and accepted Napoleon’s offer.

Despite his misgivings about the constitutionality of the purchase, Jefferson finally agreed to send the treaty to the U.S. Senate for ratification, noting privately, “The less we say about constitutional difficulties the better.” Despite his concerns, the treaty was ratified and the Louisiana Purchase now ranks as the greatest achievement of Jefferson’s presidency.

The United States Senate agrees to purchase Louisiana.

With the Louisiana Purchase in October 20,1803, the United States purchased approximately 828,000,000 square miles of territory from France, thereby doubling the size of the young republic. What was known as Louisiana Territory stretched from the Mississippi River in the east to the Rocky Mountains in the west and from the Gulf of Mexico in the south to the Canadian border in the north. Part or all of 15 states were eventually created from the land deal, which is considered one of the most important achievements of Thomas Jefferson’s presidency.

The acquisition of the Louisiana Territory for the bargain price of less than three cents an acre was among Jefferson’s most notable achievements as president. American expansion westward into the new lands began immediately, and in 1804 a territorial government was established. On April 30, 1812, exactly nine years after the Louisiana Purchase agreement was made, the first state to be carved from the territory Louisiana was admitted into the Union as the 18th U.S. state.
