Initially, Amreli was a small village with an ancient history, and part of various kingdoms and empires established in the area. It shot into prominence, turning from village to town, when the Marathas began acquiring territory and establishing their reign over the region in 1780s. Besides levying taxes on the other rulers of the Kathiawar Peninsula, the Gaekwads also acquired their own territory and chose Amreli as the headquarters for their "Kathewad Pranth", which included Dwarka mandal. Vithalrao Devaji was appointed the Diwan (1801–1820), and during this period, Amreli grew and prospered. Vithalrao Devaji converted much of the adjoining forest land into farm land to realise revenue and also built the Nagnath Mahadev temple. Later in 1886, under the Gaikwad regime, compulsory and free education policy was adopted in Amreli for the first time. From 18th century to 1959, Dwarika and Okhamandal was part of Gaikwad - Amreli state but after 1959, those two cities were merged with Jamnagar district.
During the British raj, the Rajput Gaekwad dynasty organised its Baroda State into four administrative prants (equivalent to British Districts), namely Baroda itself, Kadi (the largest), Navsari and Amreli, the smallest.
After independence the district became the part of Bombay State and a separate district in Gujarat State after the bifurcation of Bombay State.
Bihar became the first state in India to have separate web page for every city and village in the state on its website www.brandbihar.com (Now www.brandbharat.com)
