The Koeri (spelt as Koiry or Koiri), also referred to as Kushwaha and more recently self-described as Maurya in several parts of northern India are an Indian non-elite caste, found largely in Bihar and Uttar Pradesh, whose traditional occupation was agriculture. According to Arvind Narayan Das they were horticulturist rather than agriculturists. Koeris have attempted Sanskritisation— as part of social resurgence. During the British rule in India, Koeris were described as "agriculturalists" along with Kurmis and other cultivating castes. They are described as a dominant caste in various opinions. Bihar's land reform drive of 1950s benefitted the groups like Koeris, and they were able to consolidate their landholdings at the cost of big landlords, whose possession witnessed a liquidation. It is argued that these reforms weren't percolated down to the most vulnerable groups in agrarian society, the Schedule Castes, but the traditional agrarian relations based on caste did witness some changes. In the backdrop of this change many new landlords of post reform period hailed from groups like Koeris. In post-independence India, Koeris have been classified as Upper Backwards by virtue of being part of the group of four of the OBC communities in Bihar, who acquired land overtime, adopted improved agricultural technology and attained political power to become a class of rising Kulaks in the agricultural society of India. In some of the districts of Bihar, they have also participated in the Naxalite–Maoist insurgency against the feudal order. In parts of northern India, they, besides Yadavs, Jats and Kurmis, are considered as largest politically organised peasant community. The Koeris are found in Saran district and are also distributed more heterogeneously across Munger, Banka, Khagaria, Samastipur, East Champaran, West Champaran and Bhojpur district. Outside India, the Koeris are distributed among the Bihari diaspora in Mauritius where they were taken as indentured labourers. They also have a significant population residing in Nepal.
