A metre gauge railway was commenced in 1897 from Ahmedabad to Ahmednagar, through Parantij near the princely state of Ambliara. The Scott College, which was modeled on British public schools, was located at Sadra, where the sons of the native rulers or Indian Princes received education. There were other English language institutes and schools at Mansa Sadra and Idar. After the Second Anglo Maratha War that occurred during 1803- 1805, the states came under the British dominion and administration. After the decline of the Maratha Empire, in the year 1811, the British East India Company stipulated to collect and pay the yearly tribute of the Mahi Kantha states, over to the ruler of the princely state of Baroda.
Later in the year 1820, the British took over the administration of the entire territory approving to collect and pay over the tribute free of expense to Baroda, while the state of Baroda was pledged not to interfere with the management and administration or to send troops. During the 1830s, and later in 1857 and 1867, a few disturbances occurred in the region and the Mahi Kantha Agency remained in peace until the year 1881, when the Bhils of Pol state revolted against their chief and extracted a settlement of their claims from the chief.
The princely states in the Mahi Kantha Agency acceded to the newly formed Union of India after the nation attained independence from the British Government of India. The territory was reorganized and restructured into districts of Bombay State. In the year 1960, the Indian state of Bombay was divided along linguistic lines, and the region of Mahi Kantha was incorporated as a part of the newly formed state of Gujarat.
