Q. Maharaja Ranjit Singh’s western expansion was checked by whom?
Answer:
Tripartite Treaty of 1838
Notes: The Tripartite Treaty of 1838 involved the British, Sikhs, and Shah Shuja. It halted Maharaja Ranjit Singh's further western ambitions by restoring Shah Shuja to Kabul with joint Anglo-Sikh assistance, consolidating the British sphere of influence in Afghanistan and checking Sikh expansion westward.
