Japanese occupation of Singapore in the context of "Greater East Asia Co-Prosperity Sphere"

Singapore, officially the Republic of Singapore, is an island country and city-state in Southeast Asia. Its territory comprises one main island, 63 satellite islands and islets, and one outlying islet. The country is about one degree of latitude (137 kilometres or 85 miles) north of the equator, off the southern tip of the Malay Peninsula, bordering the Strait of Malacca to the west, the Singapore Strait to the south along with the Riau Islands in Indonesia, the South China Sea to the east and the Straits of Johor along with the State of Johor in Malaysia to the north.

In its early history, Singapore was a maritime emporium known as Temasek; subsequently, it was a major constituent of several successive thalassocratic empires. Its contemporary era began in 1819, when Stamford Raffles established Singapore as an entrepôt trading post of the British Empire. In 1867, Singapore came under direct British control as part of the Straits Settlements. During World War II, Singapore was occupied by Japan in 1942 and returned to Britain as a Crown colony following Japan's surrender in 1945. Singapore gained self-governance in 1959 and in 1963 became part of the new federation of Malaysia, alongside Malaya, North Borneo and Sarawak. Ideological differences led to Singapore's expulsion from the federation two years later; it became an independent sovereign country in 1965. After early years of turbulence and despite lacking natural resources and a hinterland, the nation rapidly developed to become one of the Four Asian Tigers.

The Colony of Singapore was a Crown colony of the United Kingdom that encompassed what is modern-day Singapore from 1946 to 1959. During this period, Christmas Island, the Cocos (Keeling) Islands, and Labuan were also administered from Singapore. Singapore had previously been established as a British colony since 1824, and had been governed as part of the Straits Settlements since 1826. The colony was created when the Straits Settlements was dissolved shortly after the Japanese occupation of Singapore ended in 1945. The power of the British Government was vested in the governor of Singapore. The colony eventually gained partial internal self-governance in 1955, and lasted until the establishment of the State of Singapore in 1958, with full internal self-governance granted in 1959.

After a few years of self-governance, Singapore went on to merge with Malaya, Sarawak and North Borneo (Sabah) to form Malaysia on 16 September 1963, thereby completely ending 144 years of British rule in Singapore. Due to differing views in dealing with political, economic and racial issues, Singapore would eventually cease to be a part of Malaysia and become an independent sovereign country on 9 August 1965.

The Provisional Government of Free India or, more simply, Azad Hind, was a short-lived Japanese-controlled provisional government in India. It was established in exile in Japanese-occupied Singapore during World War II in October 1943 and has been considered a puppet state of the Empire of Japan.

It was a part of the political movement originating in the 1940s outside India with the purpose of allying with the Axis powers to liberate India from British rule. It was established by Indian nationalists in exile during the latter part of the World War II in Singapore with monetary, military and political assistance from Imperial Japan.

The Malayan Communist Party (MCP), officially the Communist Party of Malaya (CPM), was a Marxist–Leninist and anti-imperialist communist party which was active in British Malaya and later, the modern states of Malaysia and Singapore from 1930 to 1989. It was responsible for the creation of both the Malayan Peoples' Anti-Japanese Army and the Malayan National Liberation Army.

The party led resistance efforts against the Japanese occupation of Malaya and Singapore during World War II, and later fought a war of national liberation against the British Empire during the Malayan Emergency. After the departure of British colonial forces from the Federation of Malaya, the party fought in a third guerrilla campaign against both the Malaysian and Singaporean governments in an attempt to create a communist state in the region, before disbanding in 1989. Today, due to historical connotations surrounding the MCP, communism as an ideology remains a taboo political topic in both countries.

Pulau Tekong (Singapore English pronunciation: /ˈtəkɒŋ/ TUH-kong), also known colloquially as Tekong or Tekong Island, is Singapore's largest outlying island. It lies off the northeastern coast of the mainland, to the east of Pulau Ubin. Since the 1980s, Pulau Tekong has been used by the Singapore Armed Forces (SAF) as a restricted military training ground, with public access prohibited. Transport for permitted personnel is provided via the SAF Changi Ferry Terminal located at Changi Beach.

Historically, various pre-colonial maps recorded the island under different names, and the origins of the name "Tekong" remain the subject of several theories. Pulau Tekong was previously inhabited by a multi-ethnic population of Malays, Chinese and Indians who established agricultural and fishing kampongs across the island. During the British colonial period, the island played a modest role in regional trade and rubber and vegetable farming sustained its economy. During the Japanese occupation of Singapore, residents of Tekong were subjected to forced labour, and many of the island's villages were eventually abandoned following the war.

Sook Ching was a mass killing that occurred from 18 February to 4 March 1942 in Singapore after it fell to the Japanese. It was a systematic purge and massacre of 'anti-Japanese' elements in Singapore, with the Singaporean Chinese particularly targeted by the Japanese military during the occupation. However, Japanese soldiers engaged in indiscriminate killing and did not try to identify who was 'anti-Japanese.' Singapore was a crucial strategic point in World War II. From 8 February to 15 February, the Japanese fought for control of the city. The combined British and Commonwealth forces surrendered in a stunning defeat to the outnumbered Japanese on 15 February which led to its fall. The loss of Singapore was and still is Britain's largest surrender in history.

Three days later after the fall, on 18 February, the occupying Japanese military began mass killings of a wide range of "undesirables", who were mostly ethnic Chinese, influenced by the events of the Second Sino-Japanese War that was raging simultaneously as far back as 1937. The operation was overseen by the Imperial Japanese Army's Kempeitai, its secret police. Along with Singapore, the Sook Ching was subsequently also extended to include the Chinese population in Malaya, which was also under occupation by the Japanese. Concurrently, non-Chinese individuals were also not completely spared in other parts of Asia under Japanese occupation. The Japanese also brutally subjugated civilians in Burma and Thailand, with estimates of up to 90,000 additional deaths. Many of these victims were also forced to work on the Siam–Burma Railway, infamously known as the Death Railway.
