Nepal

Nepal the most mountainous country on earth lying between India and the Tibetan Autonomous Region of China, Nepal contains Mount Everest (29,035 ft; 8,850 m), the tallest mountain in the world. Along its southern border, Nepal has a strip of level land that is partly forested, partly cultivated. North of that is the slope of the main section of the Himalayan range, including Everest and many other peaks higher than 8,000 m. 

The first civilizations in Nepal, which flourished around the 6th century B.C., were confined to the fertile Kathmandu Valley where the present-day capital of the same name is located. It was in this region that Prince Siddhartha Gautama was born c. 563 B.C. Gautama achieved enlightenment as Buddha and spawned Buddhism. 

Nepali rulers' early patronage of Buddhism largely gave way to Hinduism, reflecting the increased influence of India, around the 12th century. Though the successive dynasties of the Gopalas, the Kiratis, and the Licchavis expanded their rule, it was not until the reign of the Malla kings from 1200–1769 that Nepal assumed the approximate dimensions of the modern state. 

The kingdom of Nepal was unified in 1768 by King Prithvi Narayan Shah, who had fled India following the Moghul conquests of the subcontinent. Under Shah and his successors, Nepal's borders expanded as far west as Kashmir and as far east as Sikkim (now part of India). A commercial treaty was signed with Britain in 1792 and again in 1816 after more than a year of hostilities with the British East India Company.
