One of the most significant factors in Bangladesh's foreign policy is its close relationship with Muslim countries. Geographically Bangladesh belongs to South Asia and culturally Bangladeshis are not as close to Arabs, Persians or Turks as Pakistanis or North Indians are. Some Muslim states have even interpreted this movement as an act of ruin of Islamic brotherhood. The Indo-Pakistani war, which began on December 3, and the surrender of the Pakistani army to the joint command of the Indian and Bangladeshi armies, fueled this suspicion. After independence, the Mujib government immediately proclaimed itself a secular and socialist country, which further increased suspicions. After gaining independence, there was no recognition for Bangladesh by any Muslim country. The existence of the Indian Army on Bangladeshi soil until March 1972 created suspicions about the sovereignty of the newly independent country. The Pakistani government's threat to sever diplomatic relations with countries cooperating with Bangladesh also played an important role. The Government of Pakistan withdrew from the Commonwealth when Bangladesh was admitted into the organisation. Some states that had weaknesses towards Bangladesh could not express their support due to the confusing circumstances. Cairo and Beirut can be mentioned here as perfect examples of this. However, with the departure of the Indian army and the gradual intervention of the Bangladesh government, the situation began to improve. Malaysia and Indonesia recognized Bangladesh in March 1972. Both countries supported Bangladesh's bid for membership in the United Nations. Afghanistan also came out in favor of Bangladesh in this debate; recognized Bangladesh... halfway through the paper... the Constitution took place. 'Bismillahir Rahmanir Rahim' was included in the preamble of the constitution through a proclamation in 1978. In the same proclamation, secularism, one of the principles of the state, was also eliminated. Article 12, which prohibited the patronage of any type of state religion, was also deleted. The new leadership did all this for two main reasons: to satisfy their countrymen who were reluctant towards the Mujib government for its "secular stance" which had led to the rise of Islamic sentiments. among themselves” and to secure much-needed financial help from Arab countries to finance its ambitious economic programs. At this stage Bangladesh's relations with Muslim countries were very cordial. Bangladesh has been benefited both economically and politically. The process of developing relations with Muslim countries reached its peak at this stage.
