of the capital to Delhi. New Delhi designed by the British architect Edwin Lutyens was inaugurated in 1931 after its construction was delayed due to World War I. New Delhi was officially declared as the seat of the Government of India after independence in 1947. Post-Independence (1947–present) During the partition of India, around five lakh Hindu and Sikh refugees, mainly from West Punjab fled to Delhi, while around three lakh Muslim residents of the city migrated to Pakistan. Ethnic Punjabis are believed to account for at least 40% of Delhi's total population and are predominantly Hindi-speaking Punjabi Hindus. Migration to Delhi from the rest of India continues (), contributing more to the rise of Delhi's population than the birth rate, which is declining. The States Reorganisation Act, 1956 created the Union Territory of Delhi from its predecessor, the Chief Commissioner's Province of Delhi. The Constitution (Sixty-ninth Amendment) Act, 1991 declared the Union Territory of Delhi to be formally known as the National Capital Territory of Delhi. The Act gave Delhi its own legislative assembly along Civil lines, though with limited powers. After 1967 relations between Hindus and Muslims deteriorated to the level that there was a significant uptick in the number of riots and other disruption of civil life. One of the most significant was the 1973 riot in Bao Hindu Rao area, which resulted in the injury of 18 police officers and financial losses estimated to be around 500,000 Rupees, according to police sources. Another significant riot happened on 5 May 1974 in the Sadar Bazar area between Hindus and Muslims in which 11 people were killed and 92 were injured. This riot was the worst in Delhi since independence. The Centre for the Study of Developing Societies carried out a survey in nearby areas that showed significant division between Hindus and Muslims who saw each other negatively. In 1966, an inscription of the Mauryan Emperor Ashoka (273-236 BCE) was discovered near Sriniwaspuri. Two sandstone pillars inscribed with the edicts of Ashoka were brought to by Firuz Shah Tughluq in the 14th century already exist in Delhi.
