The Indonesian Revolution was a struggle for independence from Dutch colonial rule that began after World War II. It started in 1945 when leaders like Sukarno and Mohammad Hatta declared Indonesia's independence. The revolution involved both diplomatic efforts and armed conflict, as the Indonesian people sought to establish a sovereign nation. The conflict lasted until 1949, when the Dutch formally recognized Indonesia's independence following international pressure and negotiations. The revolution was significant in shaping Indonesia's national identity and laid the foundation for its future as a democratic state.
