The edict of the Emperor Ashoka (273 to 136 B.C) was found in Saurashtra and Sopara near Bombay. Satrya Kshatrapas under the Kushana emperor seemed to have ruled over Daman District during the first century, A.D. The Coins of Bhumaka and Nahapan, the kshaharata rulers were discovered in the surrounding areas of Surat District. Ushavadatta, son-in-law of Nahapan, is said to have provided ferries on rivers Dhanuha Dhamana, Parada and Tapi.
This is the earliest reference of these rivers and the names of the places, i.e. Dahanu, Daman and Pardi, remained unchanged for the last 2000 years. The District seems to have been subjected to the rule of Gautamaputra Satakarnin, about 125 A.D., who drove away the Kshaharatas. But Satavahana's rule was short lived.
Rudraman I, grandson of Chastan of Kadamaka branch of Kshatrapas reconquered a large part of Western India including the sea-board from the river Mahi in Gujarat to Ratnagiri by about 150 A.D. from Satavahana ruler, Satakarni, and Daman district again passed under the rule of Kshatrapa Vijayasen (234-239 A.D.) who seems to have ruled over the district till 249 A.D. Abhir king Ishwarasena of Nasik, who conquered the western part of the Deccan from the Satavahanas seems to have been laid by Gautamaputra Yajnashri, campaigns the Kshatrapas from 180 to 200 A.D.
The District seems to have been subjected to the rule of traikutakas during the 5th century, A.D. The Lata Country was ruled by Rashtrakutas of Malkhed in the Deccan directly till 808 A.D. by the successors, Govinda II (575- 795 A.D), Druvaraja - I (795-800 A.D) and Govinda III (800 - 808 A.D.).
