This article is misleading and somewhat inaccurate. Although the historical accuracy of any events taking place over 2500 years ago may be difficult to ascertain, it is well known that the story goes more like this:
Sakyamuni left his "home life" which was really a life of luxury and decadence at the age of 29 to search for the end of human suffering. He learned from various Indian masters all that they could teach him, and he quickly absorbed all they had to offer. He proceeded on a path of asceticism, basically starving oneself for a prolonged period of time, in order to try and find an end to suffering. After six years of this he realized that it was not The Way (to enlightenment), as he collapsed and almost died -- he would have died before attaining Enlightenment or The Truth and he realized that asceticism is not the way to cultivate The Way.
Meditating deeply under the Bodhi tree, Siddartha attained total wisdom and was awakened to the "true reality of things." That moment was his enlightenment and he stayed silent for seven weeks (or 40 days in some sources) and then, finally began teaching the Four Noble Truths. This article implies that he began teaching and the material finally evolved into "The Four Noble Truths" which is not the case. He attained enlightenment and then proceeded, for the next 40-some years until his death, to tirelessly teach and demonstrate The Dharma (what we now call the collection of his teachings).
For those interested in where he was born, Buddha was born in what is now Nepal, although the actual land area of Nepal is smaller today because when the British colonized India a portion of Nepal also came under their control -- when the British abdicated "occupying" India, they returned all the territory to India -- however, part of the territory that they held was originally Nepalese, so Nepal almost magically became smaller, although by international agreement it seems that India should return this territory -- depending on your point on view.
For more, accurate information, I would encourage all those with an interest in Buddhism to read from multiple sources and multiple translations. Truly, Dharma is a superb thing -- it is the liberating message for all of mankind, and it is unfortunate that it has become clouded in this many years since The Blessed One last walked the earth. Really, the actual "birth" and "death" of Sakyamuni are just appearances -- in Buddhism birth and death are small segments of a continuous transformation.

The vocabulary will become familiar to you over time so do not fret if there are unfamiliar words. It is all about patience, and trying to truly understand who we are. It is all about The Truth.
