The attacks in Bombay are rooted in Indian history. India was under muslim rule for hundreds of years until the British took them out of power in 1857. The Islamists in India and Pakistan are still PO'ed and think they should be returned to power. This conflict is pretty much localized to the Indian subcontinent. The scary part is that both sides in this ongoing conflict have nukes.

Main article: Mughal Empire
The Mughal Empire was a product of various Central Asian invasions into the Indian subcontinent. It was founded by the Timurid prince Babur in 1526 with the destruction of the Delhi sultanate, with its capital in Agra. Babur's death some years later, and the indecisive rule of his son, Humayun, brought a degree of instability to Mughal rule. The resistance of the Afghani Sher Shah, through which a string of defeats had been dealt to Humayun, significantly weakened the Mughals. Just a year before his death, however, Humayun managed to recover much of the lost territories, leaving a substantial legacy for his son, the 13 year old Akbar (later known as Akbar the Great), in 1556. Under Akbar, consolidation of the Mughal Empire occurred through both expansion and administrative reforms. After Akbar, Jahangir and Shah Jahan came to power. Subsequently, Aurangazeb ruled vast areas include Afghanisthan, Pakistan, India and Bangladesh. He ruled India by changing the existing status quo and lead the country well provided justice to the people. [17][8]
The empire ruled most of present-day India, Pakistan, Bangladesh and Afghanistan for several centuries, before it declined in the early 18th century, which led to India being divided into smaller kingdoms and princely states. The Mughal dynasty was eventually dissolved by the British Empire after the Indian rebellion of 1857.[17][8] It left a lasting legacy on Indian culture and architecture. Famous buildings built by the Mughals, include: the Taj Mahal, the Red Fort, the Badshahi Mosque, the Lahore Fort, the Shalimar Gardens and the Agra Fort. During the empire's reign, Muslim communities flourished all over India, particularly in Gujarat, Bengal and Hyderabad. Various Sufi orders from Afghanistan and Iran were very active throughout the region. Consequently, more than a quarter of the population converted to Islam.[17]
