Hindus (Hindustani: [ˈɦɪndu] (listen); ) are persons who regard themselves as culturally, ethnically, or religiously adhering to aspects of Hinduism

Historically, the term has also been used as a geographical, cultural, and later religious identifier for people living in the Indian subcontinent

The term “Hindu” trace back to Old Persian which derived these names from the Sanskrit name Sindhu (सिन्धु ), referring to the river Indus

The Greek cognates of the same terms are “Indus” (for the river) and “India” (for the land of the river)

The term “Hindu” also implied a geographic, ethnic or cultural identifier for people living in the Indian subcontinent around or beyond the Sindhu (Indus) River

By the 16th century CE, the term began to refer to residents of the subcontinent who were not Turkic or Muslims

Hindoo is an archaic spelling variant, whose use today may be considered derogatory

The historical development of Hindu self-identity within the local Indian population, in a religious or cultural sense, is unclear

Competing theories state that Hindu identity developed in the British colonial era, or that it may have developed post-8th century CE after the Muslim invasions and medieval Hindu–Muslim wars

A sense of Hindu identity and the term Hindu appears in some texts dated between the 13th and 18th century in Sanskrit and Bengali

The 14th- and 18th-century Indian poets such as Vidyapati, Kabir and Eknath used the phrase Hindu dharma (Hinduism) and contrasted it with Turaka dharma (Islam)

The Christian friar Sebastiao Manrique used the term ‘Hindu’ in a religious context in 1649

In the 18th century, European merchants and colonists began to refer to the followers of Indian religions collectively as Hindus, in contrast to Mohamedans for groups such as Turks, Mughals and Arabs, who were adherents of Islam

By the mid-19th century, colonial orientalist texts further distinguished Hindus from Buddhists, Sikhs and Jains, but the colonial laws continued to consider all of them to be within the scope of the term Hindu until about mid-20th century

Scholars state that the custom of distinguishing between Hindus, Buddhists, Jains and Sikhs is a modern phenomenon

At more than 1

2 billion, Hindus are the world’s third-largest religious group after Christians and Muslims

The vast majority of Hindus, approximately 966 million (94

3% of the global Hindu population), live in India, according to the 2011 Indian census

After India, the next nine countries with the largest Hindu populations are, in decreasing order: Nepal, Bangladesh, Indonesia, Pakistan, Sri Lanka, the United States, Malaysia, the United Arab Emirates and the United Kingdom

These together accounted for 99% of the world’s Hindu population, and the remaining nations of the world combined had about 6 million Hindus as of 2010
