quickly suppressed. When the Second World War broke out, nationalism in British India had already divided into religious movements. Many Sikhs and other minorities supported the Hindus, who promised a secular multicultural and multireligious society, and Muslim leaders in Lahore passed a resolution to work for a Muslim Pakistan, making the Punjab region a center of growing conflict between Indian and Pakistani nationalists. At the end of the war, the British granted separate independence to India and Pakistan, setting off massive communal violence as Muslims fled to Pakistan and Hindu and Sikh Punjabis fled east to India. The British Raj had major political, cultural, philosophical, and literary consequences in the Punjab, including the establishment of a new system of education. During the independence movement, many Punjabis played a significant role, including Madan Lal Dhingra, Sukhdev Thapar, Ajit Singh Sandhu, Bhagat Singh, Udham Singh, Kartar Singh Sarabha, Bhai Parmanand, Choudhry Rahmat Ali, and Lala Lajpat Rai. At the time of partition in 1947, the province was split into East and West Punjab. East Punjab (48%) became part of India, while West Punjab (52%) became part of Pakistan. The Punjab bore the brunt of the civil unrest following partition, with casualties estimated to be in the millions. Another major consequence of partition was the sudden shift towards religious homogeneity occurred in all districts across Punjab owing to the new international border that cut through the province. This rapid demographic shift was primarily due to wide scale migration but also caused by large-scale religious cleansing riots which were witnessed across the region at the time. According to historical demographer Tim Dyson, in the eastern regions of Punjab that ultimately became Indian Punjab following independence, districts that were 66% Hindu in 1941 became 80% Hindu in 1951; those that were 20% Sikh became 50% Sikh in 1951. Conversely, in the western regions of Punjab that ultimately became Pakistani Punjab, all districts became almost exclusively Muslim by 1951.
