Why do both India and Pakistan claim territoriality over the region of Kashmir?

The maharaja (local ruler), Hari Singh, initially wanted Kashmir to become independent - but in October 1947 chose to join India, in return for its help against an invasion of tribesmen from Pakistan.

Today, Delhi and Islamabad both claim Kashmir in full, but control only parts of it - territories recognised internationally as "Indian-administered Kashmir" and "Pakistan-administered Kashmir".

Hope this helps!
