Modern period of Chamba was started with the accession of Raja Sri Singh.
At the age of five he was appointed as the Raja of Chamba.
British period was started in Chamba under the rule of Raja Sri Singh.
Politically, Chamba state was attached with Jalandhar Division.
But after sometime it was transferred to Amritsar Division in 1862 and in the last it was attached to Lahore Division.
The Raja was married to a princess of Suket state. During his minority the economy of the state was completely shattered because of mismanagement and extravagance.
The Raja, therefore, asked for the services of an officer from the British Government and Major Blair Reid was appointed Superintendent of the State in January, 1863.
Major Reid introduced some significant and far reaching reforms. Post office, primary school, state hospital and a residency were instituted. Reforms were also introduced in the administration of forests.
The important places were linked with roads and income from revenue was increased. Raja Sri Singh died in 1870 and was succeeded by his brother Gopal Singh.
