The French were intent on spreading their revolutionary republicanism to other European states, including Britain. The British initially stayed out of the alliances of European states which unsuccessfully attacked France trying to restore the monarchy. In France a new, strong nationalism took hold enabling them to mobilise large and motivated forces. Following the execution of King Louis XVI of France in 1793, France declared war on Britain. This period of the French Revolutionary Wars was known as the War of the First Coalition. Except for a brief pause in 1802–03, the wars lasted continuously for 21 years. During this time Britain raised several coalitions against the French, continually subsidising other European states with the Golden Cavalry of St George, enabling them to put large armies in the field. In spite of this, the French armies were very successful on land, creating several client states such as the Batavian Republic, and the British devoted much of their own forces to campaigns against the French in the Caribbean, with mixed results.
