Buddha lived in northern India sometime between the mid-6th and the mid-4th centuries before the Common Era. In ancient India the title buddha referred to an enlightened being who has awakened from the sleep of ignorance and achieved freedom from suffering. According to the various traditions of Buddhism, buddhas have existed in the past and will exist in the future. Some Buddhists believe that there is only one buddha for each historical age, others that all beings will become buddhas because they possess the buddha nature --Encyclopaedia Britanica
