In British Guiana and Trinidad, white overseers and managers would take advantage of Indian coolie women and use them in sexual relationships, the Indian women were then blamed for these incidents and viewed as allegedly "loose" and promiscuous by colonial officials, and Indian women were subjected to a high rate of "wife murders" by Indian men, the Indian women were also blamed for this due to their "inconstancy" due to alleged low "sexual morality". In one incident in Trinidad, seven Indian women were impregnated at the same time by an estate manager in 1854. The managers sexual relations with Indian women caused riots, at the most significant one, at the hands of the police, 59 Indians were wounded and 5 Indians were killed, in Non Pareil in 1896, due to an Indian woman cohabiting with Gerad Van Nooten, the acting manager. The low ratio of Indian women compared to Indian men, along with the factor of Portuguese, white overseers and managers, and Chinese men having sexual relations with Indian women, aggravated the problem of rivalry for Indian women between Indian men, and drove up the value of Indian women. The incidents of overseers and managers taking sexual advantage of the women laborers led to Indian laborers causing stoppages and protests. In British Guiana the overseers and managers sexual abuse of Indian women caused Indian workers to embark on a "struggle" from 1869–1872. Conflicts due to women led to attacks against drivers and overseers. The resentment of the workers was aggravated by the use of women on estates for sexual relations.
