The multi-party democratic process of Singapore has been described as "minimal" in comparison to the state's focus on economic development and social order. According to Gordon P. Means, professor emeritus of political science at McMaster University , Singapore reinvented
11935-724: The Singapore Government to create the Singapore Armed Forces (SAF) from scratch, and Israeli instructors were brought in to train Singaporean soldiers. Military courses were conducted according to the IDF's format, and Singapore adopted a system of conscription and reserve service based on the Israeli model . Singapore still maintains strong security ties with Israel and is one of the biggest buyers of Israeli arms and weapons systems, with one recent example being
12090-471: The Temenggong's help, Raffles managed to smuggle Tengku Long back into Singapore. Raffles offered to recognise Tengku Long as the rightful Sultan of Johor, under the title of Sultan Hussein , as well as provide him with a yearly payment of $ 5000 and another $ 3000 to the Temenggong; in return, Sultan Hussein would grant the British the right to establish a trading post on Singapore. The Treaty of Singapore
12245-550: The US-led coalition to fight terrorism, with bilateral co-operation in counter-terrorism and counter-proliferation initiatives, and joint military exercises. As Singapore has diplomatic relations with both the United States and North Korea , and was one of the few countries that have relationships with both countries, in June 2018, it hosted a historic summit between US President Donald Trump and North Korean leader Kim Jong-un ,
12400-488: The US. The capacity, volume, or storage of a reservoir is usually divided into distinguishable areas. Dead or inactive storage refers to water in a reservoir that cannot be drained by gravity through a dam's outlet works , spillway, or power plant intake and can only be pumped out. Dead storage allows sediments to settle, which improves water quality and also creates an area for fish during low levels. Active or live storage
12555-568: The United Kingdom. According to the 2024 Global Peace Index , Singapore is the 5th most peaceful country in the world. Capital punishment is a legal and enforced penalty in Singapore. The country is one of four in the developed world to retain the death penalty, along with the United States , Japan and Taiwan . Particularly, its use against drug trafficking has been a source of contention with non-governmental organisations such as Amnesty International and Human Rights Watch . The government has responded that it has "no doubts" that it
12710-773: The United States are: Luke Air Force Base in Arizona , Marana in Arizona, Mountain Home Air Force Base in Idaho , and Andersen Air Force Base in Guam . The SAF has sent forces to assist in operations outside the country, in areas such as Iraq , and Afghanistan , in both military and civilian roles. In the region, they have helped to stabilise East Timor and have provided aid to Aceh in Indonesia following
12865-535: The area flooded versus power produced, a reservoir built for hydro- electricity generation can either reduce or increase the net production of greenhouse gases when compared to other sources of power. A study for the National Institute for Research in the Amazon found that hydroelectric reservoirs release a large pulse of carbon dioxide from decay of trees left standing in the reservoirs, especially during
13020-428: The base of the dam or some distance away. In a flat river valley a reservoir needs to be deep enough to create a head of water at the turbines; and if there are periods of drought the reservoir needs to hold enough water to average out the river's flow throughout the year(s). Run-of-the-river hydro in a steep valley with constant flow needs no reservoir. Some reservoirs generating hydroelectricity use pumped recharge:
13175-465: The build, often through a temporary tunnel or by-pass channel. In hilly regions, reservoirs are often constructed by enlarging existing lakes. Sometimes in such reservoirs, the new top water level exceeds the watershed height on one or more of the feeder streams such as at Llyn Clywedog in Mid Wales . In such cases additional side dams are required to contain the reservoir. Where the topography
13330-556: The building of a reservoir at Girnar in 3000 BC. Artificial lakes dating to the 5th century BC have been found in ancient Greece. The artificial Bhojsagar lake in present-day Madhya Pradesh state of India, constructed in the 11th century, covered 650 square kilometres (250 sq mi). The Kingdom of Kush invented the Hafir , a type of reservoir, during the Meroitic period . 800 ancient and modern hafirs have been registered in
13485-442: The context of system-wide demands and supplies. In many countries large reservoirs are closely regulated to try to prevent or minimize failures of containment. While much of the effort is directed at the dam and its associated structures as the weakest part of the overall structure, the aim of such controls is to prevent an uncontrolled release of water from the reservoir. Reservoir failures can generate huge increases in flow down
13640-612: The country continuously since full internal self-government was achieved in 1959, and holds a supermajority in Parliament . One of the five founding members of ASEAN , Singapore is also the headquarters of the Asia-Pacific Economic Cooperation Secretariat, the Pacific Economic Cooperation Council Secretariat, and is the host city of many international conferences and events . Singapore
13795-615: The country's third prime minister. Lee Hsien Loong's tenure included the 2007–2008 financial crisis , the resolution of a dispute over land ownership at Tanjong Pagar railway station between Singapore and Malaysia, the introduction of the two integrated resorts (IRs), located at the Marina Bay Sands and Resorts World Sentosa , and the COVID-19 pandemic . The PAP suffered its worst ever electoral results in 2011, winning just 60% of votes, amidst debate over issues including
13950-750: The death penalty is by no means uncontested internationally" and that the report contains "grave errors of facts and misrepresentations". From 1938 to 2023, sexual relations between men were technically illegal under Section 377A of the Penal Code , first introduced during British colonial rule. During the last few decades, this law was mostly unenforced and pressure to repeal it increased as homosexuality became more accepted by Singaporean society. Meanwhile, sexual relations between women had always been legal. In 2022, Prime Minister Lee Hsien Loong announced that Singapore would repeal 377A, effectively decriminalising homosexual behaviour. Nevertheless, he added that
14105-530: The delivery of fresh water to Singapore, and access by the Singapore Armed Forces to Malaysian airspace. Border issues exist with Malaysia and Indonesia, and both have banned the sale of marine sand to Singapore over disputes about Singapore's land reclamation. Some previous disputes, such as the Pedra Branca dispute , have been resolved by the International Court of Justice . Piracy in
14260-460: The developed world Naturally occurring lakes receive organic sediments which decay in an anaerobic environment releasing methane and carbon dioxide . The methane released is approximately 8 times more potent as a greenhouse gas than carbon dioxide. As a human-made reservoir fills, existing plants are submerged and during the years it takes for this matter to decay, will give off considerably more greenhouse gases than lakes do. A reservoir in
14415-507: The downstream river to maintain river quality, support fisheries, to maintain downstream industrial and recreational uses or for a range of other purposes. Such releases are known as compensation water . The units used for measuring reservoir areas and volumes vary from country to country. In most of the world, reservoir areas are expressed in square kilometers; in the United States, acres are commonly used. For volume, either cubic meters or cubic kilometers are widely used, with acre-feet used in
14570-594: The end of the 14th century, its ruler Parameswara was attacked by either the Majapahit or the Siamese, forcing him to move to Malacca where he founded the Sultanate of Malacca . Archaeological evidence suggests that the main settlement on Fort Canning Hill was abandoned around this time, although a small trading settlement continued in Singapore for some time afterwards. In 1613, Portuguese raiders burned down
14725-440: The environmental impacts of dams and the reservoirs that they contain. Some impacts, such as the greenhouse gas production associated with concrete manufacture, are relatively easy to estimate. Other impacts on the natural environment and social and cultural effects can be more difficult to assess and to weigh in the balance but identification and quantification of these issues is now commonly required in major construction projects in
14880-457: The fighting for Singapore were heavy, with a total of nearly 85,000 personnel captured. About 5,000 were killed or wounded, of which Australians made up the majority. Japanese casualties during the fighting in Singapore amounted to 1,714 killed and 3,378 wounded. The occupation was to become a major turning point in the histories of several nations, including those of Japan , Britain , and Singapore. Japanese newspapers triumphantly declared
15035-499: The first decade after flooding. This elevates the global warming impact of the dams to levels much higher than would occur by generating the same power from fossil fuels . According to the World Commission on Dams report (Dams And Development), when the reservoir is relatively large and no prior clearing of forest in the flooded area was undertaken, greenhouse gas emissions from the reservoir could be higher than those of
15190-800: The first-ever meeting between the sitting leaders of the two nations. It also hosted the Ma–Xi meeting in 2015, the first meeting between the political leaders of the two sides of the Taiwan Strait since the end of the Chinese Civil War in 1950. The Singaporean military, arguably the most technologically advanced in Southeast Asia, consists of the Army , the Navy , the Air Force and
15345-413: The flow in highly managed systems, taking in water during high flows and releasing it again during low flows. In order for this to work without pumping requires careful control of water levels using spillways . When a major storm approaches, the dam operators calculate the volume of water that the storm will add to the reservoir. If forecast storm water will overfill the reservoir, water is slowly let out of
15500-555: The formal surrender of Japanese forces in the region from General Seishirō Itagaki on behalf of General Hisaichi Terauchi on 12 September 1945. Meanwhile, Tomoyuki Yamashita was tried by a US military commission for war crimes, but not for crimes committed by his troops in Malaya or Singapore. He was convicted and hanged in the Philippines on 23 February 1946. Much of the infrastructure in Singapore had been destroyed during
15655-479: The hill into houses. Earlier service reservoirs were built on Mount Emily (1878), Pearl's Hill (1903), and Bukit Timah Hill . The size of the Fort Canning Reservoir is 30 million gallons. A spring used to exist on the west side of Fort Canning Hill and served as a source of water in the early days of Singapore. The spring was called pancur larangan or "forbidden spring", where the women of
15810-580: The hydroelectric reservoirs there do emit greenhouse gases, it is on a much smaller scale than thermal power plants of similar capacity. Hydropower typically emits 35 to 70 times less greenhouse gases per TWh of electricity than thermal power plants. A decrease in air pollution occurs when a dam is used in place of thermal power generation, since electricity produced from hydroelectric generation does not give rise to any flue gas emissions from fossil fuel combustion (including sulfur dioxide , nitric oxide and carbon monoxide from coal ). Dams can produce
15965-596: The influx of foreign workers and the high cost of living. On 23 March 2015, Lee Kuan Yew died , and a one-week period of public mourning was observed nationwide. Subsequently, the PAP regained its dominance in Parliament through the September general election , receiving 69.9% of the popular vote, although this remained lower than the 2001 tally of 75.3% and the 1968 tally of 86.7%. The 2020 election held in July saw
16120-439: The introduction of the non-constituency members of parliament in 1984 to allow up to three losing candidates from opposition parties to be appointed as MPs. Group representation constituencies (GRCs) were introduced in 1988 to create multi-seat electoral divisions, intended to ensure minority representation in parliament. Nominated members of parliament were introduced in 1990 to allow non-elected non-partisan MPs. The constitution
16275-546: The island became a global centre for rubber sorting and export. Singapore was not greatly affected by the First World War (1914–18), as the conflict did not spread to Southeast Asia . The only significant event during the war was the 1915 Singapore Mutiny by Muslim sepoys from British India, who were garrisoned in Singapore. After hearing rumours that they were to be sent to fight the Ottoman Empire ,
16430-432: The landscape is relatively flat. Other service reservoirs can be storage pools, water tanks or sometimes entirely underground cisterns , especially in more hilly or mountainous country. Modern reserviors will often use geomembrane liners on their base to limit seepage and/or as floating covers to limit evaporation, particularly in arid climates. In the United Kingdom, Thames Water has many underground reservoirs built in
16585-498: The legal tradition established during British rule and with substantial local differences. Criminal law is based on the Indian Penal Code originally intended for British India , and was at the time as a crown colony also adopted by the British colonial authorities in Singapore and remains the basis of the criminal code in the country with a few exceptions, amendments and repeals since it came into force. Trial by jury
16740-477: The main island, training involving activities such as live firing and amphibious warfare are often carried out on smaller islands, typically barred to civilian access. However, large-scale drills, considered too dangerous to be performed in the country, have been performed in other countries such as Brunei, Indonesia, Thailand and the United States. In general, military exercises are held with foreign forces once or twice per week. Due to airspace and land constraints,
16895-469: The merger would prevent Singapore from becoming a haven for communism. To obtain a mandate for a merger, the PAP held a referendum on the merger . This referendum included a choice of different terms for a merger with Malaysia and had no option for avoiding merger altogether. On 16 September 1963, Singapore joined with Malaya, the North Borneo, and Sarawak to form the new Federation of Malaysia under
17050-672: The merger, the Singaporean government and the Malaysian central government disagreed on many political and economic issues. Despite an agreement to establish a common market, Singapore continued to face restrictions when trading with the rest of Malaysia. In retaliation, Singapore did not extend to Sabah and Sarawak the full extent of the loans agreed to for economic development of the two eastern states. Talks soon broke down, and abusive speeches and writing became rife on both sides. This led to communal strife in Singapore, culminating in
17205-470: The modern use of rolled clay. The water stored in such reservoirs may stay there for several months, during which time normal biological processes may substantially reduce many contaminants and reduce turbidity . The use of bank-side reservoirs also allows water abstraction to be stopped for some time, for instance when the river is unacceptably polluted or when flow conditions are very low due to drought . The London water supply system exhibits one example of
17360-527: The new country, the development of its military forces became a priority. In addition, in October 1971, Britain pulled its military out of Singapore, leaving behind only a small British, Australian and New Zealand force as a token military presence. A great deal of initial support came from Israel , a country unrecognised by Singapore's neighbouring Muslim-majority nations of Malaysia and Indonesia. The Israel Defense Forces (IDF) commanders were tasked by
17515-761: The new port. The island was then nominally ruled by Tengku Abdul Rahman , the Sultan of Johor , who was controlled by the Dutch and the Bugis . However, the Sultanate was weakened by factional division: Abdul Rahman , the Temenggong of Johor to Tengku Abdul Rahman, as well as his officials, were loyal to the Sultan's elder brother Tengku Long , who was living in exile in Penyengat Island , Riau Islands . With
17670-521: The newspaper about the construction quality, stability and leakages from the reservoir. The structure of the reservoir on top of the hill rather than sunken into the hill (like Fort Canning reservoir) appears to have been the root cause of the public concern. When filtered water was first imported from Gunong Pulau in Johor, beginning in 1929, it was stored in Pearl's Hill Reservoir. The South End Reservoir
17825-407: The next half-century. Economic growth continued throughout the 1980s, with the unemployment rate falling to 3% and real GDP growth averaging at about 8% up until 1999. During the 1980s, Singapore began to shift towards high-tech industries, such as the wafer fabrication sector, in order to remain competitive as neighbouring countries began manufacturing with cheaper labour. Singapore Changi Airport
17980-415: The operating rules may be complex. Most modern reservoirs have a specially designed draw-off tower that can discharge water from the reservoir at different levels, both to access water as the water level falls, and to allow water of a specific quality to be discharged into the downstream river as "compensation water": the operators of many upland or in-river reservoirs have obligations to release water into
18135-517: The population has also affected the way the SAF has been designed, with a small active force and a large number of reserves. Singapore has conscription for all able-bodied males at age 18, except those with a criminal record or who can prove that their loss would bring hardship to their families. Males who have yet to complete pre-university education, are awarded the Public Service Commission (PSC) scholarship, or are pursuing
18290-481: The pre-flooded landscape, noting that forest lands, wetlands, and preexisting water features all released differing amounts of carbon dioxide and methane both pre- and post-flooding. The Tucuruí Dam in Brazil (completed in 1984) had only 0.4 times the impact on global warming than would generating the same power from fossil fuels. A two-year study of carbon dioxide and methane releases in Canada concluded that while
18445-655: The press as well as some civil and political rights. In 2023, Singapore was ranked 129th out of 180 nations by Reporters Without Borders on the global Press Freedom Index . Freedom House ranks Singapore as "partly free" in its Freedom in the World report, and the Economist Intelligence Unit ranks Singapore as a "flawed democracy", the second freest rank of four, in its " Democracy Index ". All public gatherings of five or more people require police permits, and protests may legally be held only at
18600-442: The public nor elites had experience with democracy" helped create Singapore's political culture, as dominated by status-focused hierarchies committed to economic development. The legacy of Asian values and the limited political culture within Singapore has led to the country being described as "classic illustration of soft authoritarianism", and "profoundly illiberal". The judicial system is based on English common law , continuing
18755-437: The quality of the water and the ecology of the surrounding area. Many reservoirs now support and encourage less formal and less structured recreation such as natural history , bird watching , landscape painting , walking and hiking , and often provide information boards and interpretation material to encourage responsible use. Water falling as rain upstream of the reservoir, together with any groundwater emerging as springs,
18910-453: The repeal will not affect the recognition of "traditional familial and societal norms," including how marriage is defined, leaving the legal status of same-sex marriage unchanged for the time, although the possibility of civil unions was not officially ruled out. Lee described this as a compromise between the conservative (and often religious) and progressive elements of Singaporean society to prevent further political fracturing. The law
19065-646: The reservoir at Fort Canning in 1928. Jalan Eunos Service Reservoir is a service reservoir located along Kaki Bukit Avenue 4 in Singapore . It is found in the northern part of Kaki Bukit estate near the Paya Lebar Air Base and is therefore part of the Bedok planning area . The reservoir provides water supply to the eastern regions of Singapore and stores treated water mainly from Bedok Reservoir . It can reportedly hold 22 million gallons/ 100,000 cubic metres of water. Access to this service reservoir
19220-432: The reservoir began on 1 April 1927 on the former site of a large artillery barracks and parade ground to help supplement the large impounding reservoirs. The reservoir was constructed in two sections: the southern section was ready for water storage by 1 August 1928, and the final work completed by the middle of January 1929. Water is pumped from the large reservoirs into the service reservoirs, thus enabling water to flow down
19375-638: The reservoir prior to, and during, the storm. If done with sufficient lead time, the major storm will not fill the reservoir and areas downstream will not experience damaging flows. Accurate weather forecasts are essential so that dam operators can correctly plan drawdowns prior to a high rainfall event. Dam operators blamed a faulty weather forecast on the 2010–2011 Queensland floods . Examples of highly managed reservoirs are Burrendong Dam in Australia and Bala Lake ( Llyn Tegid ) in North Wales . Bala Lake
19530-406: The ruler's household were said to bathe in ancient times In early 19th century Singapore, the spring was used to provide clean drinking water for all ships stopping at the port until the demand exceeded the capacity by 1830. The spring then dried up as wells were dug around the hill. A cache of Javanese-style gold ornaments dating to the mid-14th century was discovered when workers were excavating for
19685-699: The same sex were not wrong at all or not wrong most of the time, up from 10% in 2013. The survey found that 27% felt the same way about same-sex marriage (an increase from 15% in 2013) and 30% did so about same-sex couples adopting a child (an increase from 24% in 2013). In 2021, six Singaporeans protested for improved trans protections in the educational system outside the Ministry of Education headquarters at Buona Vista . Pimps often traffic women from neighbouring countries such as China , Malaysia and Vietnam at their brothels as well as rented apartments and hostels for higher profit margins when they get
19840-481: The settlement, and the island faded into obscurity for the next two centuries. By then, Singapore was nominally part of the Johor Sultanate . The wider maritime region and much trade was under Dutch control for the following period after the 1641 Dutch conquest of Malacca . The British governor Stamford Raffles arrived in Singapore on 28 January 1819 and soon recognised the island as a natural choice for
19995-952: 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. Singapore's history dates back at least eight hundred years, having been a maritime emporium known as Temasek and subsequently
20150-433: The structure and responsibility of governance. The President is the head of state . The governance of Singapore is separated into three branches: The president is directly elected by popular vote for a renewable six-year term. Requirements for this position, which were enacted by the PAP government, are extremely stringent, such that only a handful of people qualify for the candidacy. These qualifications include that
20305-627: The subject of academic debates, it is nevertheless known from various documents that Singapore in the 14th century, then known as Temasek , was a trading port under the influence of both the Majapahit Empire and the Siamese kingdoms, and was a part of the Indosphere . These Indianised kingdoms were characterised by surprising resilience, political integrity and administrative stability. Historical sources also indicate that around
20460-573: The surrounding forested catchments, or off-stream reservoirs , which receive diverted water from a nearby stream or aqueduct or pipeline water from other on-stream reservoirs. Dams are typically located at a narrow part of a downstream of a natural basin. The valley sides act as natural walls, with the dam located at the narrowest practical point to provide strength and the lowest cost of construction. In many reservoir construction projects, people have to be moved and re-housed, historical artifacts moved or rare environments relocated. Examples include
20615-587: The temples of Abu Simbel (which were moved before the construction of the Aswan Dam to create Lake Nasser from the Nile in Egypt ), the relocation of the village of Capel Celyn during the construction of Llyn Celyn , and the relocation of Borgo San Pietro of Petrella Salto during the construction of Lake Salto . Construction of a dammed reservoir will usually require the river to be diverted during part of
20770-529: The terms of the Malaysia Agreement . Under this Agreement, Singapore had a relatively high level of autonomy compared to the other states of Malaysia. Indonesia opposed the formation of Malaysia due to its own claims over Borneo and launched Konfrontasi ("Confrontation" in Indonesian) in response to the formation of Malaysia. On 10 March 1965, a bomb planted by Indonesian saboteurs on
20925-606: The trade unions and Chinese schools, waged a guerrilla war against the government, leading to the Malayan Emergency . The 1954 National Service riots , Hock Lee bus riots , and Chinese middle schools riots in Singapore were all linked to these events. David Marshall , pro-independence leader of the Labour Front , won Singapore's first general election in 1955. He led a delegation to London , and Britain rejected his demand for complete self-rule. He resigned and
21080-425: The two. It was thought that reuniting with Malaya would benefit the economy by creating a common market, alleviating ongoing unemployment woes in Singapore. However, a sizeable left-wing faction of the PAP was strongly opposed to the merger, fearing a loss of influence, and hence formed the Barisan Sosialis , after being kicked out from the PAP. The ruling party of Malaya, United Malays National Organisation (UMNO),
21235-439: The use of bank-side storage: here water is taken from the River Thames and River Lee into several large Thames-side reservoirs, such as Queen Mary Reservoir that can be seen along the approach to London Heathrow Airport . Service reservoirs store fully treated potable water close to the point of distribution. Many service reservoirs are constructed as water towers , often as elevated structures on concrete pillars where
21390-575: The victory as deciding the general situation of the war. Between 5,000 and 25,000 ethnic Chinese people were killed in the subsequent Sook Ching massacre . British forces had planned to liberate Singapore in 1945/1946; however, the war ended before these operations could be carried out. After the Japanese surrender to the Allies on 15 August 1945, Singapore fell into a brief state of violence and disorder; looting and revenge-killing were widespread. British, Australian, and Indian troops led by Lord Louis Mountbatten returned to Singapore to receive
21545-410: The war, including those needed to supply utilities. A shortage of food led to malnutrition, disease, and rampant crime and violence. A series of strikes in 1947 caused massive stoppages in public transport and other services. However, by late 1947 the economy began to recover, facilitated by a growing international demand for tin and rubber. The failure of Britain to successfully defend its colony against
21700-412: The water, which tends to partition some elements such as manganese and phosphorus into deep, cold anoxic water during the summer months. In the autumn and winter the lake becomes fully mixed again. During drought conditions, it is sometimes necessary to draw down the cold bottom water, and the elevated levels of manganese in particular can cause problems in water treatment plants. In 2005, about 25% of
21855-476: The world's 33,105 large dams (over 15 metres in height) were used for hydroelectricity. The U.S. produces 3% of its electricity from 80,000 dams of all sizes. An initiative is underway to retrofit more dams as a good use of existing infrastructure to provide many smaller communities with a reliable source of energy. A reservoir generating hydroelectricity includes turbines connected to the retained water body by large-diameter pipes. These generating sets may be at
22010-487: The world. It has the third highest population density of any country in the world , although there are numerous green and recreational spaces as a result of urban planning . With a multicultural population and in recognition of the cultural identities of the major ethnic groups within the nation, Singapore has four official languages : English , Malay , Mandarin , and Tamil . English is the common language , with exclusive use in numerous public services . Multi-racialism
22165-494: Was abolished in 1970. Singapore is known for its strict laws and conservative stances on crime; both corporal punishment (by caning ) and capital punishment (by hanging ) are retained and commonly used as legal penalties. The right to freedom of speech and association is guaranteed by Article 14(1) of the Constitution of Singapore , although there are provisions in the subsequent subsection that regulate them. The government has restricted freedom of speech and freedom of
22320-420: Was amended in 1991 to provide for an elected president who has veto power in the use of past reserves and appointments to certain public offices. In 1990, Goh Chok Tong succeeded Lee and became Singapore's second prime minister. During Goh's tenure, the country went through the 1997 Asian financial crisis and the 2003 SARS outbreak. In 2004, Lee Hsien Loong , the eldest son of Lee Kuan Yew , became
22475-460: Was first expanded in 1971 and was then expanded again in 1974 to increase water supply to the east of Singapore which was developing rapidly and was in need of connection to potable water. As Singapore had gained independence by then, there were also fears that Malaysia would eventually cut off water supply from its reservoirs despite agreements made beforehand. In line with the need of Singapore for self reliance to provide its own water, Bedok Reservoir
22630-432: Was fully occupied with defending Britain, leaving Singapore vulnerable to Japanese invasion . During the Pacific War , the Japanese invasion of Malaya culminated in the Battle of Singapore . When the British force of 60,000 troops surrendered on 15 February 1942, British prime minister Winston Churchill called the defeat "the worst disaster and largest capitulation in British history". British and Empire losses during
22785-456: Was granted in 1959. The PAP, self-described as pragmatic, have a syncretic ideology combining free-market principles , civil nationalism , and welfarism . Despite promulgating restrictions on civil liberties, Singapore under the PAP has seen consistent economic growth and political stability. The most represented and popular opposition party is the centre-left Workers' Party , which holds 8 seats in Parliament. The long-standing hegemony of
22940-403: Was nonetheless the largest dry dock in the world, the third-largest floating dock , and had enough fuel tanks to support the entire British navy for six months. The base was defended by heavy 15-inch (380 mm) naval guns stationed at Fort Siloso , Fort Canning and Labrador, as well as a Royal Air Force airfield at Tengah Air Base . Winston Churchill touted it as the " Gibraltar of
23095-413: Was officially repealed on 3 January 2023. Pink Dot SG , an event held in support of the LGBT community, has drawn thousands of people annually since 2009 with increasing attendance. According to a survey conducted by the Institute of Policy Studies in 2019, Singaporean society has become more liberal on LGBT rights. In the survey, more than 20% of people said that sexual relations between adults of
23250-399: Was one of the earliest references to Singapore Island, which corresponds to a Chinese account from the third century referred to a place as Pú Luó Zhōng ( Chinese : 蒲 羅 中 ), a transcription of the Malay name for 'island at the end of a peninsula '. Early references to the name Temasek (or Tumasik) are found in the Nagarakretagama , a Javanese eulogy written in 1365, and
23405-488: Was opened in 1981 and Singapore Airlines was formed. The Port of Singapore became one of the world's busiest ports and the service and tourism industries also grew immensely during this period. The PAP has remained in power since independence.
