Abstract
Islamic Caliphate started from the Caliphate Rashidun established in 632 AD soon after the death of the Holy Prophet Muhammad صلى الله عليه وسلم ,followed by the Caliphates of Umayyad (661 AD), Abbasid (750 AD), and Ottoman in 1299 AD of which the latter was revoked forever by the first President of Turkey; Kamal Ataturk in 1924. The basic purpose for the creation of Islamic Caliphate is to establish the Din of Almighty Allah on earth by spreading international peace, harmony and by implementing principles laid down in the Holy Quran and Sunnah of the Holy Prophet Muhammad صلى الله عليه وسلم .This paper makes a case for the erection of Islamic Union having characteristics of not only of the various Caliphates but also in resemblance to the structure and functioning of the contemporary European Union. Interdisciplinary research methodology will be deployed to prepare a strong case for the establishment of Islamic Union. Discourse analysis techniques will be utilized to examine, analyse and evaluate traditional and contemporary literature on the topic. Research findings are: Islamic Union would be consisted of all existing Muslim states of the World headed by one Caliph for the establishment of Islamic Law and the purposes stated before. In modern era, we have an example of European Union which was formally established in 1993 under the Maastricht Treaty. A total of 26 countries of Europe have open their borders, 19 countries have same currency, and 27 member states of the European Union have same Parliament, a Court of Justice and other institutions to achieve the common cause of economic growth, peace and prosperity in the region to prevent war between members of the European Union. Keeping in mind the method of Caliphate Rashidun and manner of European Union, an Islamic Union would be created by all existing Islamic countries of the World. One currency can be adopted, one visa may be allowed to travel to all Muslim countries, an Islamic Court of Justice would be created and an Islamic Central Bank is suggested to be created, but it is a long process, first of all, an integration of all Muslim countries are required in different fields like the European countries first started the European Coal and Steal Community in 1952, the European Economic Community in 1957, and informally started the European Union and finally the European Union was formally established in 1993 under the Maastricht Treaty. Islamic Union is a suggested method to be adopted to move forward towards achieving the ultimate goal of Islamic Caliphate i.e., Islamic Union, based on principles laid down in the Holy Quran and Sunnah of Holy Prophet Muhammad صلى الله عليه وسلم and practically shown to us during the reign of Caliphate Rashidun.
