Anglo-Sikh Wars — Key Changes

Entry	Year	Description	Impact
N/A (Administrative Change)	1846	Establishment of a British Resident at Lahore under the Treaty of Lahore, followed by the formation of a Council of Regency under the Resident's control by the Treaty of Bhyroval. This marked the formal imposition of British administrative oversight.	Significantly eroded Sikh sovereignty, placing the administration of Punjab under de facto British control and fueling resentment among the Sikh populace and aristocracy.
N/A (Administrative Change)	1849	After the annexation of Punjab, a Board of Administration was established to govern the newly acquired territory. This board initially comprised Sir Henry Lawrence, John Lawrence, and Charles Mansel, tasked with consolidating British rule.	Introduced a 'non-regulation system' of administration in Punjab, characterized by a more direct and flexible approach, focusing on law and order, infrastructure, and revenue collection. This system proved effective in integrating Punjab into British India and maintaining peace.
N/A (Administrative Change)	1853	The Board of Administration was abolished, and Punjab was placed under a Chief Commissioner, with John Lawrence becoming the first Chief Commissioner.	Streamlined the administration, centralizing authority and further consolidating British control. This move reflected the British confidence in their hold over Punjab and the success of the 'non-regulation' system.
