The Holish Islands is an overseas-Administrative District (Province) of Zamastan in the south-western Samson Ocean, roughly 1,700 miles north of Antartique and 1,980 miles east of Ausiana. The capital and largest city of the Holish Islands is Untavia, with more than 60% of the population on the main island of Unyt. The inhabitants of the Holish Islands are called Holishans, and they are Zamastanian citizens by birth. The Holish Islands became a territory of Zamastan in 1911 under President Jean Levasseur at the end of the Elkjop War. The indigenous Holish islanders have relative history with continental Ausianans. In 2018, 4,719,000 people resided on the three islands composing the archipelago.
Settled by continental Ausianans some time between 1000 and 1200 CE, the Holish Islands were home to numerous independent chiefdoms. In 1499, Quetanan explorer Miguelito Passos was the first Adulan to arrive at the archipelago; an influx of Adulan-Euronian explorers, traders, and whalers arrived shortly after leading to the decimation of the once isolated Indigenous community by introducing diseases such as syphilis, gonorrhea, tuberculosis, smallpox, measles, leprosy, and typhoid fever, reducing the native Holish population from between 300,000 and one million to less than 40,000 by 1870.
The Holish Islands has an area of 210 square miles (540 km2; 130,000 acres) and a population density of 12,420 per square mile, making it one of the most densely populated areas in the world. Since the 1950s, the economy has been supported by two industries: tourism and the Zamastanian Armed Forces. Three military bases belonging to Zamastan operate on the island, including the Navy's Holish Forward Navy Base and the Air Force's Kordia-Holish Airforce Base. The province attracts tourists, surfers, and scientists from around the world with its diverse natural scenery, generally warm climate, abundance of public beaches, oceanic surroundings, active volcanoes, and clear summer skies.
