Popular demands for a Constituent Assembly soon emerged. In December 1899, the U.S. War Secretary assured the Cuban populace that the occupation was temporary, that municipal and general elections would be held, that a Constituent Assembly would be set up, and that sovereignty would be handed to Cubans. Brooke was replaced by General Leonard Wood to oversee the transition. Parties were created, including the Cuban National Party, the Federal Republican Party of Las Villas, the Republican Party of Havana and the Democratic Union Party.
