Is it reasonable to consider the Crusades as early examples of Christian/European colonialism, imperialism, and barbarism, which modern Muslims sometimes suggest?

by RusticBohemian

And how does this play into the disputed lands being previous domains of the Roman Empire, which was Christian?

I answered a somewhat similar question a few years ago:

Did Crusader states make attempts at colonizing the area with European settlers?

It goes a little bit into the historiographical question of what colonialism is and why some historians think the crusades were an early attempt at colonization and why some disagree. I'm not sure if that fully answers your question but hopefully it helps!
