After Jinnah's refusal to accept northern Arakan into the Dominion of Pakistan, some Rohingya elders who supported a "jihad" movement, founded the "Mujahid" party in northern Arakan in 1947. The aim of the Mujahid party was to create an autonomous Islamic state in Arakan. By the 1950s, they began to use the term "Rohingya" which may be a continuation of the term Rooinga to establish a distinct identity and identify themselves as indigenous. They were much more active before the 1962 Burmese coup d'état by General Ne Win, a Burmese general who began his military career fighting for the Japanese in World War II. Ne Win carried out military operations against them over a period of two decades. The prominent one was Operation King Dragon, which took place in 1978; as a result, many Muslims in the region fled to neighbouring Bangladesh as refugees. In addition to Bangladesh, a large number of Rohingyas also migrated to Karachi, Pakistan. Rohingya mujahideen are still active within the remote areas of Arakan.
