jul 24, 1813 - The Louisiana Purchase between Spain and the United States of America happens with the US giving a large sum to the Bourbon Spanish government for control of Louisiana. The Loyalists are losing the Carlist war and lack enough money to fund the war effort, thus this allows them to survive a few more years before being defeated in 1815
