This scholarly monograph looks at a little-researched diaspora, originating on the Greek Aegean Island of Ikaria. Ikaria itself is a small, isolated island, close to the Turkish coast. It has had a long and independent history, with periods of autonomy and self-rule, including the short-lived Free State of Ikaria in 1912, which was the outcome of the Ikarian Revolution against the Ottoman Empire. Ikarians themselves remained quite insular until the nineteenth century, when they began emigrating. Ottoman port-cities and urban centres, as well as nearby Aegean islands, received the first Ikarian emigrants. Eventually, Ikarians found themselves in growing hubs of migration such as Egypt and the United States. By 1910, the first Ikarians had arrived in Port Pirie, South Australia, beginning a long tradition of Ikarian migration and settlement in the state. This book explores the Ikarians in South Australia between 1900 and 1945 - an under-researched period, and a contrast from most studies on Greeks in Australia, which have focused heavily on the mass migration post-World War II and post-Greek Civil War. This also leaves a gap for a later study on Ikarians in South Australia beyond 1945. The book positions itself around four key themes: emigration, settlement, community building and integration, with ideas such as localism and identity being explored as facets within those themes.
