The National flag of India is rectangular in shape and consists of three colors: Saffron, White and Green. The present form of the flag was adopted by the Constituent Assembly of India on 22 July, 1947 - 24 days prior to the formal declaration of Independence.

Symbolism:
In the national flag of India the top band is of Saffron colour, indicating the strength and courage of the country. The white middle band indicates peace and truth with Dharma Chakra. The last band is green in colour shows the fertility, growth and auspiciousness of the land.

Philosopher and Vice President of India, Dr. Sarvapalli Radha Krishnan put forward to the world the interpretation of the Indian Flag in an eloquent expression, “Bhagwa or the saffron colour denotes renunciation or disinterestedness. Our leaders must be indifferent to material gains and dedicate themselves to their work. The white in the centre is light, the path of truth to guide our conduct. The green shows our relation to (the) soil, our relation to the plant life here, on which all other life depends. The "Ashoka Chakra" in the centre of the white is the wheel of the law of dharma. Truth or satya, dharma or virtue ought to be the controlling principle of those who work under this flag. Again, the wheel denotes motion. There is death in stagnation. There is life in movement. India should no more resist change, it must move and go forward. The wheel represents the dynamism of a peaceful change”

Evolution of the Indian Flag:
Prior to the Sepoy Mutiny in 1857, the fragmented nation of India was represented by the individual flags of the various princely states. Post the Sepoy Mutiny, the British established Imperial rule in India and a flag was introduced to represent the British colony of India. The flag was blue, with the Union Jack on the upper left corner, and a star enclosed by a crown on the down right corner.

The first unofficial flag to be hoisted by the Indians happened on August 7, 1906, in Parsee Bagan, Calcutta. The rectangular flag consisted of three horizontal stripes of green, yellow and red from top to bottom. The uppermost green segment contained 8 lotuses representing 8 provinces, the middle yellow segment bore the words Bande Mataram in Sanskrit and the bottom red band had a crescent on the left and a sun on the right hand side.

A slightly modified version of the previous flag was hoisted in 1907 by Madame Cama and her group of exiled revolutionaries in Paris. The uppermost strip had 7 lotuses instead of 8 and it was the first time the color saffron was used in the flag.

In the next decade, several other concepts for the flag were proposed but they did not gain popularity. In 1921, Gandhi proposed a tricolored flag with the symbol of the spinning wheel at its center. The colors of the flag represented the dominant religions of the Indian subcontinent with clear message of promoting religious harmony. But growing demands for further modification led him to change the interpretations of the colors into something more secular. The lowermost strip of red represented sacrifice, middle green stripe represented hope and the topmost white stripe represented peace.

The version of the flag closest to the current one came into existence in 1923. It was designed by Pingali Venkayya and had the saffron, white and green stripes with the spinning wheel placed in the white section. It was hoisted on April 13, 1923 in Nagpur during an event commemorating the Jallianwallah Bagh Massacre. It was named the Swaraj Flag and became the symbol of India’s demand for Self-rule led by the Indian National Congress.

The resolution to adopt the tricolor as the National Flag of India was passed in 1931. On July 22, 1947, the Constituent Assembly of India adopted the Swaraj Flag as the National Flag of Sovereign India with the Ashok Chakra replacing the spinning wheel.

Significance of the National Flag

The National Flag of India represents the concept of secularism that the country was built upon. The austerity of the rectangular tricolor underlines the rich spiritual and philosophical history of India. The basis of the flag is the Swaraj Flag, adopted by the Indian National Congress during the Indian Freedom Struggle movement under Gandhi and is reminiscent of the same.
