The Hindu-Muslim tension increased considerably in Gujarat during the 1960s. Between 1961 and 1971, there were 685 incidents of communal violence in the urban areas of Gujarat (plus, another 114 in the rural areas). Out of the 685 incidents, 578 incidents happened in 1969 alone. Although Ahmedabad had been divided along the
caste and religious lines, it was not a communally sensitive area until the 1960s. In the 1960s, the city's
textile mills attracted a large number of migrants from other parts of the state. During 1961–71, the city's population grew by nearly 38%, resulting in the rapid growth of
slums in the eastern part of the city. However, the mid-1960s onwards, a number of under-qualified mill workers in Ahmedabad became unemployed, as the jobs went to the small units of
Surat. During the 1960s, seven large mills in Ahmedabad shut down, and around 17,000 workers lost their jobs. The Hindus were over-represented among these workers, compared to the Muslims. Several incidents led to increase in tensions between the two communities in Ahmedabad. During a three-day rally held in
Maninagar during 27–28 December 1968, the RSS supremo
M. S. Golwalkar pleaded for a
Hindu Rashtra ("Hindu nation"). In addition, Muslims around Gujarat took part in protestations against attacks on the Al-Aqsa mosque in Jerusalem, but many Hindus took slogans of Muslim solidarity as anti-national, raising tensions in the state. During these protests in Ahmedabad, allegations that slogans like "Pakistan Zindabad" were shouted, emerged. On the evening of 3 March 1969, a Hindu police officer moved a
handcart that was obstructing traffic near the
Kalupur Tower. A copy of the
Koran placed on the handcart fell on the ground, resulting in a demand for an apology by a small Muslim crowd standing nearby. The crowd soon grew, and twelve policemen were injured in the subsequent violent protests. In the end, the police officer was twice asked to apologize to the Muslims in the area. On 31 August, the Muslims of the city held a large demonstration to protest the
burning of the
Al-Aqsa Mosque in
Jerusalem. On 4 September, a Muslim sub-inspector, while dispersing a
Ramlila festive crowd, hit a table. As a result, the Hindu text
Ramayana and an
Aarti thali (plate) fell. The Hindus alleged that the police officer also kicked the sacred book. There were demands for dismissal of the officer, but the government agreed to conduct an inquiry into his behaviour. This incident, and the disparate treatment between events led to protests by Hindus, and the formation of the Hindu Dharma Raksha Samiti by the RSS leaders. The Hindu Dharma Raksha Samiti ("Hindu Religion Protection Committee") organized protests in which anti-Muslim slogans were raised. The
Bharatiya Jana Sangh leader
Balraj Madhok visited the city and made fiery speeches on 14 and 15 September. Another incident included an alleged assault on some Muslim
maulvis, who were trying to construct a mosque in the
Odhav village near Ahmedabad. == September violence ==
