In the 800s, the empire began to fall apart. One king named Langdarma took power. He was unkind to Buddhist monks. This caused much trouble. After he died, the big empire broke into many small parts. 
The Tibetan Empire was a powerful state on the Tibetan Plateau. It began with the Yarlung dynasty, which started in the Yarlung Valley in 127 BC. 
Growth happened in stages as kings took control of new areas. First, a leader named Namri Songtsen united many nearby clans. He gained control of the area around Lhasa before 618. 
Religion also changed as the empire grew larger. King Songtsen Gampo helped introduce Buddhism to Tibet. 
At its greatest size, the empire was truly huge. It reached its peak under the ruler Tritsuk Detsen. 

Eventually, the empire began to fall apart in the 9th century. This started after the death of King Tritsuk Detsen in 838. His brother, Langdarma, took the throne after a period of trouble. Langdarma targeted Buddhist monasteries and many practitioners. This caused the unified empire to dissolve. 
The Tibetan Empire was a powerful state centered on the high Tibetan Plateau. It emerged from the expansions of the Yarlung dynasty during the 7th century. 
The empire's growth began with the unification of local clans. A leader named Namri Songtsen rose to power by overcoming neighboring groups. He conquered the Kingdom of Sumpa in the early 7th century. By the time he died around 618, he controlled the area near Lhasa. His government sent embassies to the Chinese Sui dynasty in 608 and 609. 
Songtsen Gampo, the 33rd king of the Yarlung dynasty, was the first great emperor. He moved the capital from Yungbulakang Palace to Lhasa. He was a skilled diplomat and a strong military leader. In 635–636, he defeated the Tuyuhun people near Lake Koko Nur. This victory helped him control important trade routes into China. He also famously requested a Chinese princess for marriage. After military campaigns, the Chinese emperor provided Princess Wencheng, who arrived in 641.
During this era, the empire underwent significant cultural and religious shifts. Songtsen Gampo is credited with introducing Buddhism to Tibet. He worked to develop the Tibetan language and script to translate Buddhist texts. 
The empire reached its greatest territorial extent under the ruler Tritsuk Detsen. 

Maintaining such a large state required complex administration and diplomacy. The empire used various divisions, such as the "Four Horns," to manage its territory.
The empire began to dissolve in the 9th century due to internal conflict. The murder of Tritsuk Detsen in 838 by his brother Langdarma triggered this decline. Langdarma's reign saw the targeting of Nyingma monasteries and Buddhist practitioners. This period of instability led to the fragmentation of the unified state.
