Here's an experimental timeline we made in 2011 to mark the launch of our new Buddhist Centre Online. It's presented here as a multi-media slideshow (with integrated movies and audio). It's a whopping 53 minutes long - so feel free to download from Vimeo and watch at your leisure (we've posted a smaller version too under resources!)...
The timeline starts in 1925 with the birth of Sangharakshita, the community's founder, and ends in 2010 with the launch of the 'Triratna Story', which you can also read as a free eBook.
Thanks to Viriyalila for assembling this!
