Republic of West Florida -

The region had recently been purchased by the United States from Spain as part of the Louisiana Purchase. The locals, however, were not at all taken with the prospect of a new government, especially as they were already in the process of kicking out the Spanish. So they declared themselves an independent nation in September 1810.

The West Floridians named their new capital St. Francisville, and a president was elected to run the fledgling country. But it wasn't to last. In December, the United States forcibly annexed the area and West Florida was no more. St. Francisville, meanwhile, ended up in Louisiana.

Over the next two months, the Paris Commune governed the "City of Light" as an independent sovereign state.

The prospect of Japanese rule irked the locals to the point where on May 23, 1895, they proclaimed the establishment of a new country, the Republic of Formosa. Nonetheless, just 155 days after the birth of their nation, the Japanese waded ashore and took over the Republican capital Tainan.

But the Slovene people fought back. They declared their homeland a sovereign state, the Republic of Slovene Styria, and over the next few years effectively engaged in guerilla warfare with their unwelcome occupiers.

Republic of South Maluku -

The Republic of South Maluku was an unrecognized secessionist republic that used the Dutch withdrawal from Indonesia to declare itself an independent, sovereign nation in 1950. In the process, nearly 13,000 South Moluccans followed their former colonial rulers back to the Netherlands, where they settled for good (pictured).

Independence was short-lived, however. With the Dutch having deserted, Indonesian authorities moved to take back control of the errant state. By 1963, South Maluku had been reintegrated into the Maluku Islands archipelago.

Republic of Katanga -

Out of the violence and turmoil that was Congo in the early 1960s was born the Republic of Katanga, which claimed its independence on July 11, 1960. The bold move was declared by Congolese businessman and politician Moïse Tshombe.

Republic of Katanga -

Katanga's independence came after Belgium had withdrawn from the Congo. The former colonial power wanted nothing more to do with the ethnic strife engulfing the African country. Tshombe saw an opportunity to fill the political vacuum left by Brussels. But Katanga's mineral wealth also played an important part in the secession.

The Katanga Republic, though, failed to be recognized as a state by the wider world. And as proxy Cold War conflict broke out across the region, people simply lost interest in Katanga. By 1963, Moïse Tshombe was languishing abroad in exile. His republic vanished the following year.

East Timor -

By removing itself from East Timor, Portugal left the door open for Indonesia to invade the country and brutally stamp its authority on the islanders. In a vain attempt to govern themselves, the Timorese declared themselves independent. By early 1976, however, Indonesian strongman Suharto had effectively closed the country down.

Independence was restored in 2002. Suharto died in 2008. Today, the country is known as the Democratic Republic of Timor-Leste.
