Sukarno and Mohammad Hatta proclaim the independence of Indonesia, igniting the Indonesian National Revolution against the Dutch Empire.

Sukarno was an Indonesian statesman, orator, revolutionary, and nationalist who was the first president of Indonesia, serving from 1945 to 1967.

Mohammad Hatta was an Indonesian statesman, nationalist, and independence activist who served as the country's first vice president as well as the third prime minister. Known as "The Proclamator", he and a number of Indonesians, including the first president of Indonesia, Sukarno, fought for the independence of Indonesia from the Netherlands. Hatta was an important figure during the Indonesian national awakening and during the national revolution. As a youth he was politically active in both the Netherlands and the Indies, which led him to be imprisoned in the Boven Digoel concentration camp for his activism. He also played a crucial role in the proclamation of Indonesian independence, being the second person to sign the declaration besides Sukarno, thus making him one of the founders of Indonesia.

The Proclamation of Indonesian Independence was read at 10:00 Tokyo Standard Time on Friday, 17 August 1945 in Jakarta. The declaration marked the start of the diplomatic and armed resistance of the Indonesian National Revolution, fighting against the forces of the Netherlands and pro-Dutch civilians, until the latter officially acknowledged Indonesia's independence in 1949. The document was signed by Sukarno and Mohammad Hatta, who were appointed president and vice-president respectively the following day.
