Was The Byzantine Empire In The Second Crusade?

Question

????

Answer 1

Second crusade 1145 -1149 AD
Byzanine Empire - 330 - 1453 AD

Manuel I Komnenos was Byzantine emporer during the second crusade and had an alliance with the pope so he effectively handled the movement of the second crusade through his kingdom without to much damage.

Answer 2

Yes, to its great distress. About the only accomplishment of this crusade was the pillaging of the Balkan dependencies of the Christian Byzantine Empire by the armies of both France and the Holy Roman Empire. It was in terms of its announced intentions a dismal failure.
