There must be a number of ways, no?

Read the announcments

Read adventure log

SPEAK with players.

The forum is a sort of log of the entire activity, at least in the last 10-13 years or so.  

There are multiple ways of seeing MD history, depending what interests you.

The adventure kind of story is the adventure log, that stopped at some point and only presents a select and adjusted scenario.

The announcements is a 5000 pages long summary of what happend and when

md-archives is a nicely put, but seldom updated archive of things you can find in MD

 

In so many years of activity that spreads on parallel threads and topics, its impossible to have one single and simple line of history. 

It is like the history of the world, it depends on what exactly you are looking for to know. You can look at the history of global relations, or the history of a country, or the history of a single person, or the history and evolution of the tectonic plates.

 

Asking older players can help you find more about a specific thing, but many times very old players become fossils and they only know what happened in their age, unaware of further developments.

 

Myself, as creator and developer of this world, i can't tell such a story, i can just remember random events sometimes.
