Founding years of modern Singapore in the context of "State of Singapore (Malaysia)"

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 self-governance of Singapore was carried out in several stages. Since the founding of Singapore in 1819, Singapore had been under the colonial rule of the British. The first local elections on a limited scale for several positions in the government of Singapore started in 1948 following an amendment to the Constitution of Singapore.

This was further amended with the Rendel Constitution, strengthening local representation. Singapore was granted full internal self-government in 1959, but the colonial administration still controlled external relations and shared control of several key internal policies such as internal security.

The history of the modern state of Singapore dates back to its founding in the early 19th century; however, evidence suggests that a significant trading settlement existed on the island in the 14th century. The last ruler of the Kingdom of Singapura, Parameswara, was expelled by the Majapahit or the Siamese before he founded Malacca. Singapore then came under the Malacca Sultanate and subsequently the Johor Sultanate. In 1819, British statesman Stamford Raffles negotiated a treaty whereby Johor would allow the British to locate a trading port on the island, ultimately leading to the establishment of the Crown colony of Singapore in 1867. Important reasons for the rise of Singapore were its nodal position at the tip of the Malay Peninsula flanked by the Pacific and Indian Oceans, the presence of a natural sheltered harbour, as well as its status as a free port.

During World War II, Singapore was invaded and occupied by the Japanese Empire from 1942 to 1945. When the Japanese surrendered, Singapore reverted to British control, with increasing levels of self-government being granted, resulting in Singapore's merger with the Federation of Malaya to form Malaysia in 1963. However, social unrest, racial tensions, and political differences between Singapore's governing People's Action Party (PAP) and Malaysia's Alliance Party resulted in Singapore's expulsion from Malaysia. Singapore became an independent republic on 9 August 1965.

Indian Singaporeans are Singaporeans of Indian or broader South Asian ancestry. As of the 2020 census, they constitute approximately 9.0% of the country's residents, representing the third largest ethnic group in Singapore. In Singapore, "Indian" is an umbrella term defined in both geographical and ethnic-cultural contexts as pertaining to South Asia and bears no necessary relation to the contemporary Republic of India. Some Singaporeans of South Asian ancestry would simply just consider themselves "Singaporean", viewing themselves as distinct from the "India Indians" in terms of culture, identity and social reality.

The historical presence of ancient India influenced the indigenous Malay culture long before the founding of modern Singapore by the British Empire in 1819. Early Indian settlement was largely transient, composed primarily of male workers and soldiers. By the mid-20th century, however, the community had become more established, exhibiting a balanced gender ratio and a diversified age distribution. This period marked the emergence of a cohesive Indian Singaporean identity within the evolving social fabric of the island.

Christians in Singapore constitute 19% of the country's resident population, as of the most recent census conducted in 2020. Christianity is the second largest religion in the country, after Buddhism and before Islam. In 2020, about 37.1% of the country's Christians identified as Catholic with 62.9% labeled as 'Other Christians', most of which identify as Protestant, with some identifying as Orthodox or other minority Christian denominations.

Christianity was first introduced to Singapore by Anglicans, who were among the first British settlers to arrive shortly after the founding of a British colony by Stamford Raffles. The proportion of Christians among Singaporeans has increased in the last few decades: 9.9% in 1980; 12.7% in 1990; 14.6% in 2000 and 18.9% in 2020. A growing number of Singaporeans are converting to the faith or were born into Christian families.
