Indian Independence day -- August 15

, observed annually on 15 August, is a national holiday in India commemorating the nation's independence from Kingdom of Great Britain [Commonly known as United Kingdom] on 15 August 1947. India attained independence following anindependence movement noted for largely nonviolent resistance and civil disobedience led by the Indian National Congress (INC). Independence coincided with the partition of India, in which the British Indian Empire was divided along religious lines into the Dominions of India and Pakistan; the partition was accompanied by violent riots and mass casualties, and the displacement of nearly 15 million people due to sectarian violence.

On 15 August 1947, Jawaharlal Nehru, who had become the first Prime Minister of India that day, raised the Indian national flag above the Lahore Gate of the Red Fort in Delhi. On each subsequent Independence Day, the Prime Minister has raised the flag and given a speech.

The holiday is observed throughout India with flag-hoisting ceremonies, parades and cultural events. Indians celebrate the day by displaying the national flag on their attire, accessories, homes and vehicles; by listening to patriotic songs, watching patriotic movies; and bonding with family and friends. Books and films feature the independence and partition in their narrative. Separatist and militant organisations have often carried out terrorist attacks on and around 15 August, and others have declared strikes and used black flags to boycott the celebration.
