Who created the class system in rwanda?

Can you please give more context to the question?

The early German colonizers created the class system in Rwanda.

Explanation:

Before the German invasion of Rwanda, the major communities like Hutus, Tutsis, and Twas in the region comprised of Rwanda and Burundi all shared an equal status irrespective of the fact that the Tutsis were in power and ruled the region. Though the Tutsis were the ones who controlled the region, the were a minority outnumbered by the Hutus. The German colonizers inculcated in the Tutsis the feeling of superiority over the other communities because they believed the Tutsis came from the regions closer to Europe.
