A brief history of Tai Chi
Tai Chi often traces its root back to Taoist and Buddhist influence from the Song Dynasty with some insisting that the well known Taoist Master Zang Sanfeng invented the system.
These mythical origins however are hard to prove, instead, we can say that Tai Chi emerged in the Chen Village some time in the 17th century in the form of the Chen Family martial art. Up until the time of Master Yang Lu Chan, the art likely went by other names, including possibly "touch boxing" (Zhan Quan) or "Soft Boxing" (Mian Quan)
Yang Lu Chan was the first to use the term Taiji Quan (Tai Chi Chuan) to describe the art after an imperial court scholar described it thus in the mid 19th Century. Master Yang learned in the Chen village for roughly 18 years and emerged with his version of their martial arts, which would become known as the 'Yang Style Tai Chi'.
Other family styles would emerge from either Chen Style or Yang Style Tai Chi including the Wu Style, Sun style and Hao Style. But without doubt, it was the Yang Style that would be most widely spread, largely due to one of Yang Lu Chans sons, the famous master Yang Cheng Fu.
