What's the right verb in English to describe the process of one culture of one nation coming to another nation and starting to dominate there so much that the original culture of that second nation eventually disappears?
Geblerians attacked Finelia and fully conquered it. Soon all citizens of Finelia were forced to learn and speak Geblerian. No Finelian would be allowed to get any key position in the society unless he was fluent enough in Geblerian. And since Geblerians were much more versed in science and literature a lot of Geblerian words and terms started getting into Finelian. Within the following 20 years, with the birth and growth of a new generation of Finelians, situation was changed drastically. Young Finelians refused to communicate in Finelian, which they were now understanding less and less and used only to communicate with their parents. So, another ten years later Finelian culture was completely __________________ by the Geblerain culture.
- devoured ?
- engulfed ?
- superseded ?

Verbs like "superseded" and "replaced" don't strike me as suitable here because they don't seem to reflect the intrinsic aspect of the process.
