The Royal Expedition (Spanish: Expedición Real), also known as Don Carlos' Expedition, was an 1837 operation in the late stages of the First Carlist War undertaken by the Carlist insurgents. Marking the highest point of Carlist control, it ended with a humiliating defeat and laid the groundwork for the end of the war in 1839.
