Why the Europeans unwilling to help tewdros to modernic his army?

The Europeans were unwilling to help Emperor Tewdros II of Ethiopia modernize his army because they were concerned about the potential for Ethiopia to become a powerful regional power. The Europeans were also wary of the potential for Ethiopia to become a rival to their own colonial interests in the region. Additionally, the Europeans were not interested in investing in a country that was not part of their own sphere of influence.
