In early 1946, Heinrich Harrer and Peter Aufschnaiter reached the city of Lhasa. They had spent twenty-one months traveling through the dangerous mountain passes after escaping a prison camp in British India. The high-altitude plateau was almost entirely closed to foreigners at the time. Local officials initially told the men to leave, but they eventually allowed them to stay. Lhasa was a city of stone buildings and narrow streets dominated by the Potala Palace. This massive structure stood on a hill and housed thousands of monks along with the young Dalai Lama.
Harrer and Aufschnaiter integrated into the local society during their seven-year stay. They used their engineering skills to help the city improve its infrastructure. They helped build a sewer system and created detailed maps of the capital. Most Tibetan people lived according to ancient religious traditions and slow-paced routines. Citizens wore heavy wool robes called chubas to protect themselves from the thin, freezing mountain air. Religious festivals filled the streets with bright colors and traditional music throughout the year.
In 1948, the teenage Dalai Lama sent for Harrer. The young leader was curious about the world outside the Himalayas. Harrer became his tutor, teaching him subjects like geography, science, and math. They met in a private room inside the Potala Palace. Harrer also helped the Dalai Lama build a small cinema so he could watch films from other countries. The young ruler had a keen interest in Western technology and mechanical objects like watches and cameras.
By 1950, the isolation of Tibet ended as political tensions rose. The Chinese army invaded the eastern regions of the country, and the news caused great anxiety in Lhasa. The Dalai Lama took on full political power earlier than expected to lead his people. Harrer realized that his time in the country was ending. He helped the Dalai Lama prepare for a potential escape toward the Indian border. The tranquil life of the previous years was replaced by military preparations and high-stakes diplomacy.
