Tea for horses: the Sichuan–Tibet exchange
A state-managed barter that ran for centuries and shaped an entire category of tea. Compressed dark tea exists in the form it does because it had to survive months on a mule.
From around the Tang and Song, formalised under later dynasties
A process, not a moment. This happened over a period rather than on a date, and the span is the honest answer.
A long institution rather than an event. The state monopoly arrangements change repeatedly across dynasties and TeaHQ does not attempt to fix the transitions here.

What happened
Chinese states exchanged tea for Central Asian and Tibetan horses, at times under a formal monopoly, over routes running from the Sichuan basin and Yunnan up onto the plateau. Tea travelled compressed into bricks and cakes, carried by porters and pack animals over months.
Why it matters
The format follows the route. Compression, and the long slow change that happens to tea while it is compressed and travelling, are consequences of a transport problem — and the taste that resulted became the taste that the destination expected. Tibetan butter tea, and the whole dark-tea category behind it, descend from this.
