Terra nullius-meaning land belonging to no-one-was the legal concept used by the British government to justify the settlement of Australia. This book is an article that explores Australia's "History Wars" from the inside. In 2005 the author published a book called The Invention of Terra Nullius. At the time Australian history, and law, was based on something called terra nullius. It was a term that everybody used and nobody understood. After the book was published academic historians and lawyers launched an attack on the book.
