<P> The' Taj Mahal' represents the finest and most sophisticated example of Mughal architecture . Its origins lie in the moving circumstances of its commission and the culture and history of an Islamic Mughal empire's rule of large parts of India . The distraught Mughal Emperor Shah Jahan commissioned the mausoleum upon the death of his favorite wife Mumtaz Mahal . </P> <P> Today it is one of the most famous and recognizable buildings in the world and while the large, domed marble mausoleum is the most familiar part of the monument, the Taj Mahal is an extensive complex of buildings and gardens that extends over 22.44 hectares (55.5 acres) and includes subsidiary tombs, waterworks infrastructure, the small town of' Taj Ganji' to the south and a' moonlight garden' to the north of the river . Construction of Taj Mahal began in 1632 AD, (1041 AH), on the south bank of the River Yamuna in Agra, and was substantially complete by 1648 AD (1058 AH). The design was conceived as both an earthly replica of the house of Mumtaz Mahal in paradise and an instrument of propaganda for the emperor . </P> <P> In 1607 (AH 1025) the Mughal Prince Khurrum (later to become Shah Jahan) was betrothed to Arjumand Banu Begum, the grand daughter of a Persian noble . She would become the unquestioned love of his life . They were married five years later in 1612 . After their wedding celebrations, Khurram "finding her in appearance and character elect among all the women of the time," gave her the title Mumtaz Mahal (Jewel of the Palace). </P>

When did the construction of the taj mahal end
