Shakyamuni Buddha, Siddhartha Gautama, was born in the 5th or 6th century BCE in what is now Nepal. Although historians believe there was such a person, much of his life story is shrouded in legend and myth.
According to legend, Siddhartha Gautama was the son of a king, and as a youth and young adult, he lived a sheltered and pampered life. In his late 20s, he was shocked to witness sickness, old age, and death for the first time, and he was filled with such dread he resolved to give up his royal birthright to seek the peace of mind.
After several false starts, Siddhartha Gautama eventually settled determinately into deep meditation under the famous Bodhi tree in Bodh Gaya, in North Eastern India, and realized enlightenment, at about the age of 35. From this point on he was called the Buddha, which means “one who woke up.” He spent the rest of his life teaching and died at about the age of 80, achieving NIrvana. More detail about the life of the Buddha can be read in The Life of the Buddha.
