Amnat Charoen gained city status during the reign of King Rama III. It was first administered from Nakhon Khemarat, and later from Ubon Ratchathani. It became a province in its own right on 12 January 1993, when it was split off from Ubon Ratchathani. It is thus one of the four newest provinces of Thailand, together with Nong Bua Lam Phu and Sa Kaeo, both also established in 1993, and Bueng Kan, established in 2011.

The province is overwhelmingly agricultural. In 2008, Amnat Charoen locals developed the so-called "Dhamma agriculture" model based on self-governance and aimed at making the province a hub for organic farming.

Sugarcane plantations increased from 40,688 rai in 2015 to 51,446 rai in 2016.

In the middle of the provincial seal is an image of the Buddha called Phra Mongkol Ming Muang. Also known as Phra Yai (Big Buddha), this 20 m high statue is among the most sacred in the city of Amnat Charoen.

The provincial tree is Hopea ferrea. The provincial aquatic life is the Siamese mud carp (Henicorhynchus siamensis).
