Through the turbulent eighteenth century, Awadh grew to become one of the richest and most coveted regions in all of Hindustan. Although it was nominally ruled by the Mughal emperor in Delhi, the Mughal empire itself under Muhammad Shah 'Rangeeley', and later under Shah Alam II, was in terminal decline. The British and French East India Companies were vying for control of the subcontinent. As the Seven Years' War between these European powers came to an end, and the British lost territory in other parts of the world, they became more determined to seize power in India. Meanwhile, France began a 'war of revenge' against its old enemy to restore its prestige. The French Revolutionary wars (1792-99) and the Napoleonic wars (1803-1815) would lead to even greater volatility in India. French players continued to intrigue till the last quarter of the eighteenth century in various Indian courts. Awadh's rise to prominence began when Saadat Khan Burhan-ul-Mulk (r.1722-1739) was posted there by the Mughal emperor as a demotion for failing to quell a Jat rebellion.
