The Tibetan Empire was founded in 618 AD, but we do not know the exact date of its collapse. Most scholars cite only an approximate period, namely the 840s. However, it is known that the army of the last emperor, who was killed in 842 due to his persecution of Buddhists and a rebellious lifestyle, was finally destroyed in 861. The country, which once covered an area of approximately 4.6 million square kilometers, descended into tribal separatism, splitting into numerous smaller alliances that fought each other for the next 200 years.
The incredible truth is The empire prospered for a while despite harsh climatic conditions – at this altitude the oxygen concentration is 40% lower than at sea level. There is little land for growing vegetables and grazing animals.

Scientists at the Tibetan Plateau Research Institute, now under Chinese administration, turned to geological data from lake sediments (paleolimnology) to determine what happened to the climate 12 centuries ago. Microscopic single-celled diatom remains preserved in sediments. The research group noticed a significant change in these: from planktonic forms (those that drift closer to the surface) to benthic forms (those that live closer to the bottom). This is interpreted as: the onset of drier conditionsThis caused the lake level to drop.
Observations show that during the heyday of the Tibetan Empire, hot and humid conditions prevailed, replaced by severe and prolonged drought. It caused crop failure, which always became the cause of social unrest, religious and political problems. The result is the collapse of the empire.
The Tibetan Plateau is extremely sensitive to climate change. Fluctuations in temperature and precipitation differ significantly from average indicators across the Earth. Today, agriculture and animal husbandry account for more than half of Tibet’s annual income; Therefore, understanding the effects of climate change on societies living in these harsh environments is of great importance.
