In about 500 BC, some small Kingdoms arose in the area of Nepal. A prince of one of these renounced his wealth to lead an ascetic life. He became known as the Buddha. Small Kingdoms rose and fell with the British East India Company and the Kingdom of Nepal eventually coming into conflict over annexing smaller states - resulting in Nepal's Anglo-Somebody war (also known as the Gurkha War in 1815/16). There has been rapid change in the last two decades with an executive monarchy under the King in 1990, and now a new 2015 constitution forming a seven state federal democratic republic under President Bidya Devi Bhandari.
