Sabah in the context of "Constitution of Malaysia"

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colony of the United Kingdom, Malaya became fully sovereign on 31 August 1957, and on 16 September 1963, Malaya was superseded by Malaysia when it united with Singapore, North Borneo (Sabah) and Sarawak.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 Crown Colony of North Borneo was a Crown colony on the island of Borneo established in 1946 shortly after the dissolution of the British Military Administration. The Crown Colony of Labuan joined the new Crown colony during its formation. It was succeeded as the state of Sabah through the formation of the Federation of Malaysia on 16 September 1963.

Singapore, officially the State of Singapore, was briefly one of the 14 states of Malaysia from 1963 to 1965. Malaysia was formed on 16 September 1963 by the merger of the Federation of Malaya with the former British colonies of North Borneo (Sabah), Sarawak and Singapore. This marked the end of 144 years of British rule in Singapore, which began with the founding of modern Singapore by Stamford Raffles in 1819. With a land area of approximately 670 km (260 sq mi), it was the smallest state but had the largest population and was highly urbanised, playing a central role in the national economy. As part of the integration referendum and the Malaysia Agreement, Singapore was given autonomous status including in education, labour and healthcare.

The merger was supported by the British, Malayan and Singaporean leaders as a measure to counter the influence of communism in Southeast Asia, especially through the Malayan Communist Party (MCP). The threat of communist expansion was considered serious by all parties, and the union was seen as a means to contain it through political consolidation. However, serious disagreements soon surfaced between the governments of Singapore and Malaysia, led by the People's Action Party (PAP) and the Alliance Party respectively. Conflicts arose over financial contributions, political participation and racial policies. Although a common market had been promised in exchange for Singapore's substantial tax revenues, trade barriers remained in place. In response, Singapore withheld development loans to Sabah and Sarawak. The situation was worsened when the Malay–based United Malays National Organisation (UMNO) of the Alliance and the PAP contested elections beyond their agreed jurisdictions, triggering further mistrust.

Brunei, officially Brunei Darussalam, formally known as State of Brunei, is a country in Southeast Asia, situated on the northern coast of the island of Borneo. Apart from its coastline on the South China Sea, it is completely surrounded by the Malaysian state of Sarawak, with its territory bifurcated by the Sarawak district of Limbang. Brunei is the only sovereign state entirely on Borneo; the remainder of the island is divided between its multi-landmass neighbours of Malaysia and Indonesia. As of 2025, the country had a population of 466,330, of whom approximately 64,409 resided in the capital and largest city of Bandar Seri Begawan. Its official language is Malay, and Sunni Islam is the state religion of the country, although other religions are nominally tolerated. The government of Brunei is an absolute monarchy ruled by the Sultan, and it implements a fusion of English common law and jurisprudence inspired by Islam, including sharia.

At the Sultanate of Brunei's peak during the reign of Sultan Bolkiah (1485–1528), the state is claimed to have had control over the most of Borneo, including modern-day Sarawak and Sabah, as well as the Sulu archipelago and the islands off the northwestern tip of Borneo. There are also claims to its historical control over Seludong, in which Southeast Asian scholars believe the name of the location in question is actually in reference to Mount Selurong, in Indonesia, or Serudong River in eastern Sabah. The maritime state of Brunei was visited by the surviving crew of the Magellan Expedition in 1521, and in 1578 it fought against Spain in the Castilian War.

In biology, the canopy is the aboveground portion of a plant cropping or crop, formed by the collection of individual plant crowns. In forest ecology, the canopy is the upper layer or habitat zone, formed by mature tree crowns and including other biological organisms (epiphytes, lianas, arboreal animals, etc.). The communities that inhabit the canopy layer are thought to be involved in maintaining forest diversity, resilience, and functioning. Shade trees normally have a dense canopy that blocks light from lower growing plants.

Early observations of canopies were made from the ground using binoculars or by examining fallen material. Researchers would sometimes erroneously rely on extrapolation by using more reachable samples taken from the understory. In some cases, they would use unconventional methods such as chairs suspended on vines or hot-air dirigibles, among others. Modern technology, including adapted mountaineering gear, has made canopy observation significantly easier and more accurate, allowed for longer and more collaborative work, and broaddened the scope of canopy study.

Framing, in construction, is the fitting together of pieces to give a structure, particularly a building, support and shape. Framing materials are usually wood, engineered wood, or structural steel. The alternative to framed construction is generally called mass wall construction, where horizontal layers of stacked materials such as log building, masonry, rammed earth, adobe, etc. are used without framing.

Building framing is divided into two broad categories, heavy-frame construction (heavy framing) if the vertical supports are few and heavy such as in timber framing, pole building framing, or steel framing; or light-frame construction (light-framing) if the supports are more numerous and smaller, such as balloon, platform, light-steel framing and pre-built framing. Light-frame construction using standardized dimensional lumber has become the dominant construction method in North America and Australia due to the economy of the method; use of minimal structural material allows builders to enclose a large area at minimal cost while achieving a wide variety of architectural styles.

Mount Kinabalu (Dusun: Gayo Ngaran or Nulu Nabalu, Malay: Gunung Kinabalu) is the highest mountain in Malaysia and Maritime Southeast Asia, it is located on the Island of Borneo in Sabah. With a height of 4,098 metres (13,445 ft), it is the third-highest peak of an island on Earth, the 28th highest peak in Southeast Asia, and 20th most prominent mountain in the world. The mountain is located in Ranau district, West Coast Division of Sabah, Malaysia. It is protected as Kinabalu Park, a World Heritage Site.

In 1997, a re-survey using satellite technology was conducted. It established Mount Kinabalu had a summit (known as Low's Peak) height of 4,095 m (13,435 ft) above sea level, some 6 m (20 ft) less than the hitherto published figure of 4,101 m (13,455 ft).

Nusantara is the Indonesian name of Maritime Southeast Asia (or parts of it). It is an Old Javanese term that literally means "outer islands". In Indonesia, it is generally taken to mean the Indonesian Archipelago. Outside of Indonesia, the term has been adopted to refer to the Malay Archipelago.

The word Nusantara is taken from an oath by Gajah Mada in 1336, as written in the Old Javanese Pararaton. Gajah Mada was a powerful military leader and prime minister of Majapahit credited with bringing the empire to its peak of glory. Gajah Mada delivered an oath called Sumpah Palapa, in which he vowed not to eat any food containing spices until he had conquered all of Nusantara under the glory of Majapahit.The concept of Nusantara as a unified region was not invented by Gajah Mada in 1336. The term Nusantara was first used by Kertanegara of Singhasari in Mula Malurung inscription dated 1255. Furthermore, in 1275, the term Cakravala Mandala Dvipantara was used by him to describe the aspiration of united Southeast Asian archipelago under Singhasari and marked the beginning of his efforts to achieve it. Dvipantara is a Sanskrit word for the "islands in between", making it a synonym to Nusantara as both dvipa and nusa mean "island". Kertanegara envisioned the union of Southeast Asian maritime kingdoms and polities under Singhasari as a bulwark against the rise of the expansionist Mongol-led Yuan dynasty of China.

East Malaysia (Malay: Malaysia Timur), or the Borneo States, also known as Malaysian Borneo, is the part of Malaysia on and near the island of Borneo, the world's third-largest island. East Malaysia comprises the states of Sabah, Sarawak, and the Federal Territory of Labuan. The small independent nation of Brunei comprises two enclaves in Sarawak. To the south and southeast is the Indonesian portion of Borneo, Kalimantan. East Malaysia lies to the east of Peninsular Malaysia (also known as the States of Malaya), the part of the country on the Malay Peninsula. The two are separated by the South China Sea.

East Malaysia is less populated and has fewer developed settlements than West Malaysia. While West Malaysia contains the country's major cities (Kuala Lumpur, Johor Bahru, and George Town), East Malaysia is larger and much more abundant in natural resources, particularly oil and gas reserves. In the pan-regional style, city status is reserved for only a few settlements, including Kuching, Kota Kinabalu and Miri. Various other significant settlements are classified as towns, including many with over 100,000 residents. East Malaysia includes a significant portion of the biodiverse Borneo lowland rain forests and Borneo montane rain forests.
