For nearly 900 years, from the middle of the 10th century, Ladakh was an independent kingdom, its ruling dynasties descending from the kings of old Tibet. The kingdom attained its greatest geographical extent and glory in the early 17th century under the famous king Singge Namgyal, whose domain extended across Spiti and western Tibet right up to the Mayum-la, beyond the sacred sites of Mount Kailash and Lake Mansarovar.
Ladakh became recognized as the best trade route between the Punjab and Central Asia. For centuries it was traversed by caravans carrying textiles, spices, raw silk, carpets, dyestuffs, narcotics, etc.
The famous pashmina (better known as cashmere) also came down from the high-altitude plateau of eastern Ladakh and western Tibet, through Leh, to Srinagar, where skilled artisans transformed it into shawls known the world over for their softness and warmth. Ironically, it was this lucrative trade that finally spelt the doom of the independent kingdom. It attracted the covetous attention of Gulab Singh, the ruler of Jammu in the early 19th century, who sent his general Zorawar Singh to invade Ladakh in 1834 AD. There followed a decade of war and turmoil, which ended with the emergence of the British as the paramount power in north India.
