Abyssinia (modern-day Ethiopia) was the first African state to defeat a European army in the field during the Battle of Adwa in 1896. The Ethiopian forces successfully resisted an invasion by Italy, which was attempting to establish a colony in Ethiopia. This victory was significant as it challenged the notion of European racial superiority and inspired anti-colonial movements across Africa.
