Starting in 1910, Punjabi women began trickling into California, joining a community of men who started arriving from the northern Indian province of Punjab in the 1890s. But even as their numbers grew these women remained largely invisible. Their women’s story is now being told, thanks to Nicole Ranganath, historian and assistant adjunct professor of Middle East/South Asia Studies (ME/SA) in the UC Davis College of Letters and Science. Along with amassing an archive of interviews, photographs, letters and archival footage, she has created a documentary film “Walking into the Unknown: A History of Punjabi Women in California.”
