Although such an approach proceeds rather slowly, the advantage is that Spain does not need to deploy too many troops. Within ten to twenty years, it can infiltrate the entire Sokoto Caliphate, establishing clear colonial rule over this area.
However, because the Berlin Conference accelerated the pace of colonization in Africa by various countries, Spain had no choice but to seek more effective and rapid methods to establish its own colonial rule.
Fortunately, by previously infiltrating economically, Spain had already gained the support of several indigenous states, so it didn't have to face the complete Sokoto Caliphate.
In fact, this seemingly powerful indigenous nation was already decaying. When the nation was initially established through a Holy War, the Sokoto Caliphate wielded formidable combat strength.
As the state was passed down, something called power and desire replaced fervor for religion, and devout warriors were doomed to become indulgent dragons seeking pleasure.
