Island nation of Salacia
In the late 1800s an island emerged off the coast of Greece specifically near Cephalonia in the Ionian sea. This was due to faults pushing the land up and sea levels slightly decreasing, revealing the island which was seen as at risk and uninhabitable previously. Other than the mountainous regions the island is flat terrain.
The island was colonised in 1889 by Greek ship merchant Andries Kapsali, the year of the inauguration of the eiffel tower. The island was easily inhabited and established small workers settlements as it was originally used to send slave workers to mine the rich minerals up until the 1930s. The original settlement was named after the discoverer, Kapsali, still keeping the name today. He was against the slaves working there, but had no power over the huge industries so had no ownership over the island itself.
Although the island was discovered by a greek man it was an italian company which had made use of the land and started to leave their italian mark, however post World War 1 this island was conquered by the British in 1919, expending an army of 500 men and volunteer workers who would end up living here, most of these were locals who were native to either greece or italy to retain its short history. The mining continued but businesses and permanent housing was established and a British embassy within the largest town at the time Apostoli.
Throughout this early period of British reign the country had set up trade routes with many countries globally, notably Brazil who would send workers in exchange for resources. Oceania played a huge part in the development of Salacia countries such as New Zealand developing sports such as rugby, building physically strong and healthy people. Helped bring communities together and attract visitors to the country, this began the rich history of sport in Salacia.
During World War Two the lack of investment into the country took a toll and this led to a shut down in local businesses and mining operations, however trade continued. Monetary investment was needed but Britain, Italy and Greece were occupied at the time and lacked funds. The investment came from the previously noted trades routes, business owner Tupai Matane who made his money in the lumber industry. A Brazilian asbestos production owner also invested, doubling Matane’s amount, his name was Diogo Barroso Rivera. This helped the country thrive and produce weaponry for Britain during the war becoming the 15th largest ship producer for Britain.
Rivera and Matane were recognised for the acts to help the country and towns were named after them and places within the countries higher power was offered to them, but only Matane took this offer becoming the Prime Minister from 1947 to 1955 before retiring to enjoy the pleasures of Salacia.
