The flag of Indonesia, known as the Sang Saka Merah Putih or simply the Merah Putih, is a powerful symbol of independence, courage, and national unity. Featuring two equal horizontal bands of red and white, it reflects centuries of Indonesian history and the struggle to build an independent nation. The flag was officially adopted on 17 August 1945, the day Indonesia declared independence from the Netherlands.

History of the Flag of Indonesia
The red-and-white colours have deep roots in Indonesian history. They were used by the Majapahit Empire, which ruled much of the Indonesian archipelago between the 13th and 16th centuries.
During the nationalist movement of the early 20th century, red and white became symbols of resistance to Dutch colonial rule. On 17 August 1945, when Sukarno and Mohammad Hatta proclaimed Indonesia’s independence, the red-and-white flag was raised in Jakarta.
The first flag raised at independence became known as the Bendera Pusaka, or Heirloom Flag. It was reportedly sewn by Fatmawati, the wife of Sukarno.
