I'm researching the history of the Trojan Reach and I'm having trouble pinning down a factoid - *when* did the Tyrian Lordships happen? When did it end? Is there a canon answer?

Dear Abu Dhabi,

A word search of the Traveller Integrated Timeline, and of my (unpublished) update of it gave no hits for "Tyrian".  

Of note, I own and have read the MgT Trojan Reach sector book, but have not yet "harvested" it for Timeline entries.  A word search of that PDF finds a few mentions of the Tyrian Lordships, but none with firm dates attached.  If MgT Trojan Reach is a document you are using, I don' t think there would be much else in Traveller published material which would help you expand on the information there.

Cheers,
