Lord Buddha: Buddha, born with the name Siddhartha Gautama, was a teacher, philosopher and spiritual leader who is considered the founder of Buddhism. He lived and taught in the region around the border of modern-day Nepal and India sometime between the 6th to 4th century B.C. The Buddha is undoubtedly one of the most influential figures in world history, and his teachings have affected everything from a variety of other faiths (as many find their origins in the words of the Buddha) to literature to philosophy, both within India and to the farthest reaches of the world.
