Australian historian Lyndall Ryan was in her mid-twenties when she discovered the glaring gaps and inaccuracies in the documented history of her country’s Aboriginal people. At 38, she published her first book which chronicled the early history of the relationship between the Tasmanian Aborigines and the European settlers in the region.

Four years ago, Ryan received the Australian Research Council Grant to probe the 146-year-long bloody saga of the frontier wars fought between the indigenous Australian tribes and British colonists. At 74 today, she has come out with a digital story map that records more than 170 sites of Indigenous fatalities along with historical evidence, wherever available.

The thing is, this story map only lists the places where more than six people were slain, in accordance with the traditional definition of a frontier massacre. As such, the common figure quoted by historians for frontier war causalities till a few years ago has been 20,000 Aborigines for 2,000 Europeans. However, new academic research, which also takes smaller attacks into account, has indicated that the ratio of black to white deaths could be as high as 44 to one.

But there really is no way to corroborate that. In frontier wars, the assassins and victims usually know each other. Since these slayings take place in secret, the code of silence makes detection extremely difficult. “The perpetrators would remain silent. Even after the event, they were reluctant to talk about it. Some of them kept diaries and might record the event. Some of them would tell close friends on the grounds that they remain silent. And they themselves would not come clean,” Ryan explains in a video interview.

So, all the historical evidence available today comes from what can be called as ‘white people’s sources’ – diary entries and letters of the settlers, court records, newspaper clippings, photographs. Which is why Ryan has kept this project ongoing. She believes that there are over 500 massacre sites in total, and not even half of them have been discovered till now.

The historian is now inviting the general public to share any information they may have (including hearsay stories) about those gory times to add to her research. To contribute or to view the map, click here.
