According Venerable Geshe Kelsang says in Introduction to Buddhism

According to Aboutbuddhism.org “The founder of Buddhism in this world is Buddha Shakyamuni. He was born as a royal prince in 624 BC in a place called Lumbini, which was originally in northern India but is now part of Nepal. ‘Shakya’ is the name of the royal family into which he was born, and ‘Muni’ means ‘Able One’. His parents gave him the name Siddhartha and there were many wonderful predictions about his future. In his early years he lived as a prince in his royal palace but when he was 29 years old he retired to the forest where he followed a spiritual life of meditation. After six years he attained enlightenment under the Bodhi Tree in Bodh Gaya, India.” He was subsequently requested to teach and as Venerable Geshe Kelsang says in Introduction to Buddhism ‘ As a result of this request, Buddha rose from meditation and taught the first Wheel of Dharma. These teachings which include the Sutra of the Four Noble Truths and other discourses, are the principal source of the Hinayana, or Lesser Vehicle, of Buddhism. In all Buddha Shakyamuni gave eighty-four thousand teachings. His intention in founding Buddhism was to lead living beings to permanent liberation from suffering. He realized temporary liberation from suffering and difficulties is not enough. Motivated by love and compassion his aim was to help living beings find lasting peace or nirvana. A couple of significant points that I’ve learn due to choosing to write about this religion is that the religion has 360 million followers making it the fourth largest religion in the world. Even though they have a founder Buddhists don’t believe in a supreme being or creator god. Because of its emphasis on meditation and mindfulness, Buddhism is often considered to be a form of psychology rather than a religion. The term ‘Buddhism’ was coined by Western scholars in the 1830s. Buddhists don’t actually refer to their religion as “Buddhism”.  Last but not least the first mention of the Buddha in Western writing is in the writings of Clement of Alexandria, 2 AD.
