Pandit Jawaharlal Nehru presented the National Flag of India to the Constituent Assembly of India on July 22, 1947. Our National Flag is rectangular in shape and is made from cotton, khadi, wool or silk cloth. The ratio of the width of the flag to its length is always 2:3. The National Flag has three equal horizontal stripes of different colours. There is saffron (kesari) at the top, white in the middle and green at the bottom. This is why it is also called the tricolour.
