The roots of culture in Assam goes back almost five thousand years when the first wave of humans, the
Austroasiatic people reached the Brahmaputra valley. They mixed with the later immigrant
Tibeto-Burman and the
Indo-Aryan peoples out there in prehistoric times. The last wave of migration was that of the Tai/Shan who later formed the idea of Assamese culture and its identity. The Ahoms, later on, brought some more Indo-Aryans like the Assamese Brahmins and Ganaks and Assamese Kayasthas to Assam. " According to the epic
Mahabharata and on the basis of local folklore, people of Assam (Kiratas) probably lived in a strong kingdom under the Himalayas in the era before
Jesus Christ, which led to early assimilation of various Tibeto-Burman and Autro-Asiatic ethnic groups on a greater scale. Typical naming of the rivers and spatial distribution of related ethno-cultural groups also support this theory. Thereafter, western migrations of Indo-Aryans such as those of various branches of Irano-Scythians and
Nordics along with mixed northern Indians (the ancient cultural mix already present in
northern Indian states such as Magadha enriched the aboriginal culture and under certain stronger politico-economic systems,
Sanskritisation and Hinduisation intensified and became prominent. Such an assimilated culture, therefore, carries many elements of source cultures, of which exact roots are difficult to trace and are a matter for research. However, in each of the elements of cultures in Assam, i.e. language, traditional crafts, performing arts, festivities, and beliefs, either indigenous local elements or the indigenous local elements in Sanskritised forms are always present. It is believed that Assamese culture developed its roots over 750 years as the country of
Kamarupa during the first millennium AD of
Bodo-Kachari people assimilation with
Aryan which is debatable as the idea of Assam as an entity was not present. The first 300 years of
Kamarupa was under the great
Varman dynasty, 250 years under the
Mlechchha dynasty and 200 years under the
Pala dynasty. The records of many aspects of the language, traditional crafts (silk, lace, gold, bronze, etc.) are available in different forms. When the
Tai-Shans entered the region in 1228 under the leadership of
Sukaphaa to establish
Ahom kingdom in Assam for the next 600 years, again a new chapter of cultural assimilation was written, and thus the modern form of Assamese culture developed. The original Tai-Shans assimilated with the local culture adopted the language on one hand and on the other also influenced the culture with the elements from their own. Similarly, the
Chutiya kingdom in eastern Assam, the
Koch Kingdom in western Assam and the medieval
Kachari and
Jaintia kingdoms in southern Assam provided stages for assimilation at different intensities and with different cultural-mixes. The Vaishnava Movement, a 15th-century religio-cultural movement under the leadership of
Srimanta Sankardeva and his disciples, has provided another dimension to the Assamese culture. A renewed Hinduisation in local forms took place, which was initially greatly supported by the
Koch and later by the Ahom Kingdoms. The resultant social institutions such as
namghar and
sattra –
the Vaishnav Hermitage have become part of the Assamese way of life. The movement contributed greatly towards language, literature, and performing and fine arts. On many occasions, the Vaishnav Movement attempted to introduce alien cultural attributes and modify the way of life of the common people.
Brajavali, a language specially created by introducing words from other Indian languages, failed as a language but left its traces on the
Assamese language. Moreover, new alien rules were also introduced changing people's food habits and other aspects of cultural life. This had a greater impact on the alienation of many ethnocultural and political groups in the later periods. During periods when strong politico-economic systems emerged under powerful dynasties, greater cultural assimilation created common attributes of Assamese culture, while under less powerful politico-economic systems or during political disintegration, more localized attributes were created with spatial differentiation. Time-factors for such integrations differentiations have also played an important role along with the position of individual events in the entire series of events.

British rule of Assam and in the Post-British Era. The language was standardized by American Missionaries according to that of the
Sibsagar District, the nerve center of the Ahom politico-economic system while a renewed Sanskritisation was increasingly adopted for developing Assamese language and grammar (). A new wave of Western and northern Indian influence was apparent in the performing arts and literature. Due to increasing efforts of standardization in the 19th and 20th centuries, the localized forms present in different districts and also among the remaining source-cultures with the less-assimilated ethnocultural groups have seen greater alienation. However, Assamese culture in its hybrid form and nature is one of the richest and is still under development. 20th century saw numerous self-determination and identity movement and many states were new states created in the process as most indigenous tribal communities of the state refused to accept the idea of collective Assamese identity which was imposed upon them. Many indigenous tribal communities of the state still oppose the efforts of assimilation into Assamese cultural identity. ==Composition and characteristics==
