The word Beldar is derived from two words; "bel" meaning a digging instrument, and "dar" referring to the person who handles it. They are associated with digging and carrying soil in the context of agriculture. They have also been noted for making bricks and clearing agricultural land.
They live in Madhya Pradesh, but some live in Uttar Pradesh or West Bengal. A smaller number are further east in Bangladesh or further north in Nepal.

Though fewer in number, there are Beldar who are engaged in animal husbandry, small business, industrial work and unskilled labor. Some produce and sell an alcoholic drink. Alcoholism and drug addiction is common among the Beldar. There are Beldar people doing well economically in major cities.
The Beldar people have their own folk songs and folktales. Though they speak in the Baghelkandi dialect at home, most of them also speak Bengali in Bangladesh.

They are Hindus. After cremating their dead, they worship the deceased's spirit a year later.

They perceive themselves as part of a lower caste, and others perceive them as being in this category as well. This belief holds them back socially and economically. The few Christian believers among them live in India, not Bangladesh.

Pray for the Lord to bless them materially and spiritually as a testimony of his power and goodness.
Pray for missionaries to produce stories and songs in the Beldar traditions that will lead them to seek Jesus Christ.
Pray for the Beldar people to have easy access to Christian materials in the Hindi language.
Pray for spiritual discernment and hunger among the Beldar people.
