Indonesia, officially the Republic of Indonesia, is a country in Southeast Asia and Oceania between the Indian and Pacific oceans. It consists of over 17,000 islands, including Sumatra, Java, Sulawesi, and parts of Borneo and New Guinea. Indonesia is the world's largest island country and the 14th-largest country by area, at 1,904,569 square kilometres. With over 279 million people, Indonesia is the world's fourth-most populous country and the most populous Muslim-majority country. Java, the world's most populous island, is home to more than half of the country's population.
The history of Indonesia has been shaped by its geographic position, natural resources, a series of human migrations and contacts, wars and conquests, as well as by trade, economics and politics. Indonesia is an archipelagic country of 17,000 to 18,000 islands stretching along the equator in Southeast Asia. The country's strategic sea-lane position fostered inter-island and international trade; trade has since fundamentally shaped Indonesian history. The area of Indonesia is populated by peoples of various migrations, creating a diversity of cultures, ethnicities, and languages. The archipelago's landforms and climate significantly influenced agriculture and trade, and the formation of states. The boundaries of the state of Indonesia match the 20th-century borders of the Dutch East Indies.
Tourism in Indonesia is an important component of the Indonesian economy as well as a significant source of its foreign exchange revenues. Indonesia was ranked at 20th in the world tourist Industry in 2017, also ranked as the ninth-fastest growing tourist sector in the world, the third-fastest growing in Asia and fastest-growing in Southeast Asia. In 2018, Denpasar, Jakarta and Batam are among of 10 cities in the world with fastest growth in tourism, 32.7, 29.2 and 23.3 percent respectively. The tourism sector ranked as the 4th largest among goods and services export sectors.
The culture of Indonesia has been shaped by long interaction between original indigenous customs and multiple foreign influences. Indonesia is centrally-located along ancient trading routes between the Far East, South Asia and the Middle East, resulting in many cultural practices being strongly influenced by a multitude of religions, including Buddhism, Christianity, Confucianism, Hinduism, and Islam, all strong in the major trading cities. The result is a complex cultural mixture, often different from the original indigenous cultures.
Indonesians are citizens or people who are identified with the country of Indonesia, regardless of their ethnic or religious background. There are more than 1,300 ethnicities in Indonesia, making it a multicultural archipelagic country with a diversity of languages, culture and religious beliefs. The population of Indonesia according to the 2020 national census was 270.2 million. 56% live on the island of Java, the world's most populous island. Around 95% of Indonesians are Native Indonesians, with 40% Javanese and 15% Sundanese forming the majority, while the other 5% are Indonesians with ancestry from foreign origin, such as Arab Indonesians, Chinese Indonesians, Indian Indonesians, and Indos.
Several different religions are practised in Indonesia. Indonesia is officially a presidential republic and a unitary state without an established state religion. Indonesia has the world's largest Muslim population and the first principle of Indonesia's philosophical foundation, Pancasila, requires its citizens to state the belief in "the one and almighty God". Although, as explained by the Constitutional Court, this first sila of Pancasila is an explicit recognition of divine substances and meant as a principle on how to live together in a religiously diverse society. However, blasphemy is a punishable offence and the Indonesian government has a discriminatory attitude towards its numerous tribal religions, atheist and agnostic citizens. In addition, the Aceh province officially applies Sharia law and is notorious for its discriminatory practices towards religious and sexual minorities. There are also Islamic fundamentalist movements in several parts of the country with overwhelming Muslim majorities.
Greater Indonesia was an irredentist political concept that sought to bring the so-called Malay race together, by uniting the territories of the Dutch East Indies with British Malaya and British Borneo. It was espoused by students and graduates of Sultan Idris Training College for Malay Teachers in the late 1920s, and individuals from Sumatra and Java, including Mohammad Natsir and Sukarno, on September 28, 1950. Indonesia Raya was adopted as the name of what later became the Indonesian national anthem in 1924.
The architecture of Indonesia reflects the diversity of cultural, historical, and geographic influences that have shaped Indonesia as a whole. Invaders, colonizers, missionaries, merchants, and traders brought cultural changes that had a profound effect on building styles and techniques.

The military history of Indonesia includes the military history of the modern nation of Republic of Indonesia, as well as the military history of the states which preceded and formed it. It encompassed a kaleidoscope of conflicts spanning over a millennia. The ancient and medieval part of it began as tribal warfare began among indigenous populations, and escalated as kingdoms emerged. The modern part is defined by foreign colonial occupations, battles for independence through guerrilla warfare during Indonesian National Revolution, regional conquests and disputes with neighbouring countries, as well as battles between the Republic and separatist factions. Since the formation of the Republic, the military has played significant role in state affairs. However, in Post-Suharto era, the Indonesian military has retreated from politics, yet it still possesses some influences.
The archaeology of Indonesia is the study of the archaeology of the archipelagic realm that today forms the nation of Indonesia, stretching from prehistory through almost two millennia of documented history.
