We remember Manzikert as the defeat that lost Anatolia. I'd argue Myriokephalon (1176) was the worse one and I tried to work out why.
I've been reading around the late Komnenian period and kept hitting the same thing: Manzikert (1071) gets treated as the start of Byzantine decline, while Myriokephalon (1176) barely registers outside specialist circles. The longer I looked, the more that ranking felt backwards.
Whilst Manzikert was indeed a catastrophe, the empire recovered from it. The real loss of Anatolia came in the civil wars of the 1070s, not on the field itself, and within a decade, Alexios I had seized the throne and started rebuilding. A full century of Komnenian recovery followed. By the 1170s, the empire was richer and stronger than it had been before 1071.
Myriokephalon is the defeat with no recovery after it. Manuel I marched on Iconium in 1176 with the largest Roman army in two centuries, let it get strung out through a pass in Phrygia, and watched the supply train and the rear get cut to pieces. He and the empire survived the defeat. But there was no second Alexios. Manuel died in 1180, the dynasty came apart, and the line runs more or less straight from there to 1204.
What I find interesting is why one is famous and the other isn't. Manzikert fits a clean story: emperor captured, one afternoon, "the day it all changed." Myriokephalon doesn't, because the damage shows up in what didn't happen afterward — the recovery that never came. We tend to remember the defeats we can narrate.

Genuinely curious whether people think the comparison holds, or whether I'm overcorrecting against the popular Manzikert story. Where would you put 1176 in the chain that ends in 1204?
