In 1668, England allied itself with Sweden, and with its former enemy the Netherlands, to oppose Louis XIV in the War of Devolution. Louis made peace with the Triple Alliance, but he continued to maintain his aggressive intentions towards the Netherlands. In 1670, Charles, seeking to solve his financial troubles, agreed to the Treaty of Dover, under which Louis XIV would pay him £160,000 each year. In exchange, Charles agreed to supply Louis with troops and to announce his conversion to Catholicism "as soon as the welfare of his kingdom will permit". Louis was to provide him with 6,000 troops to suppress those who opposed the conversion. Charles endeavoured to ensure that the Treaty—especially the conversion clause—remained secret. It remains unclear if Charles ever seriously intended to convert.
