When was the Kashmir issue taken to the United Nations Security Council by India?

The Kashmir issue was first taken to the United Nations Security Council by India in January 1948 following conflict between India and Pakistan over the princely state of Jammu and Kashmir. The UN called for a ceasefire and proposed a plebiscite to allow the people of Kashmir to decide their future. However; this plebiscite was never held. The issue remains one of the longest unresolved conflicts on the UN agenda; deeply affecting relations between India and Pakistan.
