Arab Indonesians are citizens of Indonesia of Arab, mainly Hadrami, descent. Restricted under Dutch East Indies' law until 1919, the community elites later gained economic power through real estate investment and trading. Currently found mainly in Java and South Sumatra, they are almost all (generally orthodox) Muslims.
Indonesia has had contact with the Arab world for hundreds of years, prior to the emergence of Islam in Indonesia. Most contact was with spice traders, but the first Arab settlements in the archipelago may date from the fifth century. Some later founded dynasties, including the Sultanate of Pontianak, while others intermingled with existing kingdoms. These early communities adopted much of the local culture, and some disappeared entirely while others formed ethnically distinct communities.
Modern Arab Indonesians are generally descended from Hadramis, the oldest record referring to Hadrami Arabs in Indonesia goes back to the 9h century AD  They were classified as "foreign orientals" along with Chinese Indonesians by the Dutch colonists, which led to them being unable to attend certain schools and restricted from travelling, and having to settle in special Arab districts, or kampung Arab. These laws were repealed in 1919.
The community elites began to build economic power through trade and real estate acquisition, buying large amounts of real estate in Batavia (modern-day Jakarta), Singapore and other parts of the archipelago. Through charity work and "conspicuous consumption", they built and protected their social capital; eventually, some Arab Indonesians joined the Volksraad, the people's council of the Dutch East Indies.
During the Indonesian National Awakening, Arab Indonesians began to experience hostility from native Indonesians owing to their foreign descent; they also experienced hostility from the Dutch. This led to the formation of organizations exclusively for Arab Indonesians beginning in 1913; these organizations viewed the Arabian peninsula as a homeland and tended to ignore Indonesia. An Indonesian nationalistic movement, Persatoean Arab Indonesia, was founded by Abdurrahman Baswedan in 1934, eventually leading to a "cultural reorientation".
Indonesian scholar Azyumardi Azra depicts Indonesians of Arab descent as wishing to purge Indonesian Islam of its indigenous religious elements. Indonesian critics of Arab influence in Indonesia point to the founding of the radical group Jemaah Islamiah (JI) and leadership of Laskar Jihad (LJ) and Front Pembela Islam by Indonesian Arabs,.
First generation immigrants are referred to as wulayātī or totok. They are a small minority of the Arab Indonesian population. The majority, muwallad, were born in Indonesia and may be of mixed heritage.
Arab Indonesians are almost all Muslim; according to the 2000 census, 98.27 percent of Arab Indonesians are Muslim, compared to 88.22 percent of the general population. Historically, most have lived in kauman, or the area around mosques, but this has changed in recent years. The majority are Sunni, following the Shafi'i school of Islamic law; a growing minority are Shia. Children are generally sent to madrasahs.
The Islam practiced by Arab Indonesians tends to be more orthodox than the local, indigenous-influenced forms like abangan. Many Arab Indonesians attempt to convince local Muslims to follow a more orthodox form of Islam as well.
