List of monarchs of the Muhammad Ali dynasty: Monarchs of the Muhammad Ali dynasty reigned over Egypt from 1805 to 1953.  Their rule also extended to Sudan throughout much of this period, as well as to the Levant, and Hejaz during the first half of the 19th century.  The Muhammad Ali dynasty was founded by Muhammad Ali Pasha, an Albanian commander in the expeditionary force sent by the Ottoman Empire in 1801 to dislodge the French occupation of Egypt led by Napoleon Bonaparte.  The defeat and departure of the French left a power vacuum in Egypt, which had been an Ottoman province since the 16th century, but in which the pre-Ottoman Mamluk military caste maintained considerable power.  After a three-year civil war, Muhammad Ali managed to consolidate his control over Egypt, and declared himself Khedive of the country.  The Ottoman Porte refused to acknowledge this title, instead recognizing Muhammad Ali by the more junior title of "Wāli" (meaning governor or viceroy) on 18 June 1805, making Muhammad Ali the successor to Ahmad Khurshid Pasha in that position.  In the years following his consolidation of power, Muhammad Ali extended Egypt's borders south into Sudan, and eastwards into the Arab Mashreq, particularly the Levant.  In 1840, his demand for hereditary control of Egypt and Sudan to be passed to his heirs and successors was accepted and confirmed by the Convention of London, but he was compelled to agree that, upon his death, control over his territories in the Mashreq would revert to the Porte.

He was amongst the first to respond to the call of Pakistan sounded by Muhammad Iqbal in 1930 (Qutote from Chaudhry Muhammad Ali, Prime Minister of Pakistan), Dr. Khursheed kamal aziz Pakistan's official historian) has described this book as "the most comprehensive and far reaching scheme aimed at furthering and elaborating the idea of Pakistan.  Waheed uz-Zaman wrote in his book, "Pakistan", Lahore, 1964, P. 168, "The book was taken into consideration by the Muslim league, while preparing the Lahore resolution and the fact the solution proposed in the confederacy of India" differed but little from the proposed by the Muslim League in March 1940.  The venear of a Confederacy, which was the main theme of his scheme, could anytime be set aside and the remainder would have precisely... Pakistan.  So scholarly and so cogent was his reasoning that men like Dr.Rajendra Prasad felt compelled to join issues with him in his books, ("Pakistan"(Bombay and Calcutta, September 1940), p 34; see also his book ""India Divided"" page 180-181).  The book was reviewed in leading newspapers and journals.  Comparatively more scholarly appraisal was in the "Tarjaman-ul-Quran" of Maulana Abul Ala Maududi.  According to Mian Kifait Ali "The idea was suggested to me by the late Choudhary Rahmat Ali's writings and I developmed it to an extent to which no one had done earlier (Letter to Dr. K.K, September 5, 1968)".  Ali also stated that originally it was proposed to publish the book under the title of "Pakistan" a typed manuscript which bore this page title was sent to the press.  Soon after he received a telegraphic message from the Muhammad Ali Jinnah that book should not appear under the pen name of "Pakistan".  It was to comply with the Quaid's directive he prepared a federal scheme and was incorporated in the introduction of the book.  Thus the book was titled as "Confederacy of India".  (Nation article, 23 December 1994 by Sarfraz Hussain Mirza, ""Confederacy of India by A Punjabi"", also in Daily Times, Cam Diary, ""Pak history in Leichester"", and article by V.P Bhatia ""'Jinnah was against the name 'Pakistan' at First"".  It was in recognition of this work of Mian Kifait Ali that he was invited to work on the committee presided over by Sir Abdullah Haroon set up in February 1940 to examine the various schemes of constitutional reforms for India and to see whether a consolidated scheme can finally be framed.  His book has been referred to as the most comprehensive schemes at demystifying and detailing the ideas regarding the inception of Pakistan, quite a lot has been written about him and his work.  Mian Kifait Ali has done "pioneering work in the evolution of Muslim political thoughts and has suffered the hardship of a pioneer… when an objective appraisal of Muslim political movement is made by the historian.  He will find an honourable place among the pioneers and selfless workers in this great field of Muslim reconstruction (Quoted by Governor Punjab, Mushtaq Ahmed Gurmani).  Famous independence-era personalities such as Abul Ala Maududi, Chaudhry Muhammad Ali, Dr. Rajendra Prasad, Vengalil Krishnan Krishna Menon, and Sardar V. Patel took issue with him.  He responded in several pamphlets.
