Deeg district was once part of Bharatpur State before its accession to India.

In August 2023, Chief Minister Ashok Gelhot declared Deeg to be a new district.

The district is located at the junction of the Mewat region and Braj region, with northern tehsils part of Mewat and southern tehsils part of Braj Bhoomi.

Muslims, mainly Meos, are largely rural and are majority in the northern tehsils which are part of Mewat.

Southern tehsils are predominantly Hindu with very small minorities percentage.
