British Malaya in the context of "Onn Jaafar"

Malaysia is a country in Southeast Asia. A federal constitutional monarchy, it consists of 13 states and three federal territories, separated by the South China Sea into two regions: Peninsular Malaysia on the Indochinese Peninsula and East Malaysia on the island of Borneo. Peninsular Malaysia shares land and maritime borders with Thailand, as well as maritime borders with Singapore, Vietnam, and Indonesia; East Malaysia shares land borders with Brunei and Indonesia, and maritime borders with the Philippines and Vietnam. Kuala Lumpur is the country's national capital, largest city, and the seat of the legislative branch of the federal government, while Putrajaya is the federal administrative capital, representing the seat of both the executive branch (the Cabinet, federal ministries, and federal agencies) and the judicial branch of the federal government. With a population of over 34 million, it is the world's 42nd-most populous country.

The country has its origins in the Malay kingdoms, which, from the 18th century on, became subject to the British Empire, along with the British Straits Settlements protectorate. During World War II, British Malaya, along with other nearby British and American colonies, was occupied by the Empire of Japan. Following three years of occupation, Peninsular Malaysia was briefly unified as the Malayan Union in 1946 until 1948 when it was restructured as the Federation of Malaya. The country achieved independence on 31 August 1957. On 16 September 1963, independent Malaya united with the then British crown colonies of North Borneo, Sarawak, and Singapore to become Malaysia. In August 1965, Singapore was expelled from the federation and became a separate, independent country.

Syonan (Japanese: 昭南, Hepburn: Shōnan; Kunrei-shiki: Syônan), officially Syonan Island (Japanese: 昭南島, Hepburn: Shōnan-tō; Kunrei-shiki: Syônan-tô), was the name for Singapore when it was occupied and ruled by the Empire of Japan, following the fall and surrender of British military forces on 15 February 1942, 6:20 p.m. local time, during World War II.

The Japanese military forces occupied Singapore after defeating the combined British, Indian, Australian, Malayan and the Straits Settlements garrison in the Battle of Singapore within 7 days. The occupation was to become a major turning point in the histories of several nations, including those of Japan, Britain, and Singapore. Singapore was renamed Syonan-to, meaning "Light of the South Island" and was also included as part of the Greater East Asia Co-Prosperity Sphere (Japanese: 大東亜共栄圏, Hepburn: Dai Tōa Kyōeiken).

Malaya, officially the Federation of Malaya, was a country in Southeast Asia from 1948 to 1963. It succeeded the Malayan Union and, before that, British Malaya. It comprised eleven states – nine Malay states and two of the Straits Settlements, Penang and Malacca. It was established on 1 February 1948.

Initially a self-governing colony of the United Kingdom, Malaya became fully sovereign on 31 August 1957, and on 16 September 1963, Malaya was superseded by Malaysia when it united with Singapore, North Borneo (Sabah) and Sarawak. Singapore was expelled on 9 August 1965, leaving the original states of Malaya along with Sarawak and Sabah – now collectively known as East Malaysia – to form modern-day Malaysia, while the former Federation of Malaya is now referred to as Peninsular Malaysia or West Malaysia.

The South-East Asian Theatre of World War II consisted of the campaigns of the Pacific War in the Philippines, Thailand, Indonesia, Indochina, Burma, India, Malaya, and Singapore between 1941 and 1945.

Japan attacked British and American territories with near-simultaneous offensives against Southeast Asia and the Central Pacific on 7/8 December 1941. Action in this theatre ended when Japan announced an intent to surrender on 15 August 1945. The formal surrender of Japan ceremony took place on 2 September 1945.

During World War I, conflict on the Asian continent and the islands of the Pacific included naval battles, the Allied conquest of German colonial possessions in the Pacific Ocean and China, the anti-Russian Central Asian revolt of 1916 in Russian Turkestan and the Ottoman-supported Kelantan rebellion in British Malaya. The most significant military action was the careful and well-executed Siege of Qingdao in China, but smaller actions were also fought at Bita Paka and Toma in German New Guinea.

All other German and Austro-Hungarian possessions in Asia and the Pacific fell without bloodshed. Naval warfare was common; all of the colonial powers had naval squadrons stationed in the Indian or Pacific oceans. These fleets operated by supporting the invasions of German-held territories and by destroying the East Asia Squadron of the Imperial German Navy.

Malaysia is a federation of thirteen states and three federal territories, which form the primary administrative divisions of the country. Eleven states and two territories are part of Peninsular Malaysia, while two states and one territory make up East Malaysia. Nine of the Peninsular states have monarchies, with the other four having appointed governors. State governments are led by chief ministers, who are appointed by the monarch or governor, provided they have the support of a majority in the state legislative assembly. The federal territories are governed directly by the national government.

Malaysia was formed through the union of various territories ruled by the United Kingdom in British Malaya and British Borneo. The federal system was created to maintain the status of the Malay sultans, who were the rulers of British protectorates in the Malay Peninsula. The Federation of Malaya was created in 1948, uniting these protectorates with two directly ruled British colonies. Malaya became independent in 1957. In 1963, Sabah and Sarawak, along with Singapore, joined with Malaya to form Malaysia. Singapore was expelled in 1965. The three federal territories–Kuala Lumpur, Labuan and Putrajaya–were created later, from land separated from existing states.

The Malayan Union (Malay: Kesatuan Malaya; Jawi: كساتوان مالايا) was a union of the Malay states and the Straits Settlements of Penang and Malacca. It was the successor to British Malaya and was conceived to unify the Malay Peninsula under a single government to simplify administration. Following opposition by the ethnic Malays, the union was reorganised as the Federation of Malaya in 1948.

Malaya, then under British administration, was gradually occupied by Japanese forces between 8 December 1941 and the Allied surrender at Singapore on 15 February 1942. The Japanese remained in occupation until their surrender to the Allies in 1945. The first Japanese garrison in Malaya to lay down their arms was in Penang on 2 September 1945 aboard HMS Nelson.

Tomoyuki Yamashita (山下 奉文, Yamashita Tomoyuki; 8 November 1885 – 23 February 1946; also called Tomobumi Yamashita) was a general in the Imperial Japanese Army during World War II. Yamashita led Japanese forces during the invasion of Malaya and Battle of Singapore. His conquest of Malaya and Singapore in 70 days earned him the sobriquet "The Tiger of Malaya". He was assigned to defend the Philippines from the advancing Allies later in the war. Although he was unable to prevent the superior Allied forces from advancing, despite dwindling supplies and Allied guerrilla action, he was able to hold on to part of Luzon until after the formal surrender of Japan in August 1945.

Under Yamashita's command, at least 350,000 to 450,000 were killed. Yamashita was in overall command during the Sook Ching massacre, the Rape of Manila, and other atrocities. After the war, Yamashita was tried for war crimes committed by troops under his command during the Japanese defense of the occupied Philippines in 1944. Yamashita denied ordering those war crimes and said that he did not have knowledge that they occurred. Conflicting evidence was presented during the trial concerning whether Yamashita had implicitly affirmed commission of these crimes in his orders and whether he knew of the crimes being committed. The court eventually found Yamashita guilty and he was executed in February, 1946. The ruling against Yamashita – holding the commander responsible for subordinates' war crimes as long as the commander did not attempt to discover and stop them from occurring – came to be known as the Yamashita standard.
