Campaign to Wala and Dagarti Land In 1890, Zarma troops invaded Wala. In the subsequent Battle of
Nasa, 12,000 warriors of the
Wala King Bazori faced off against 9,000 Zarma warriors of
Emir Babatu dan Isa. Both sides also had religious support from prominent Islamic leaders, known as “Mallams”. Babatu and his troops eventually emerged victorious and occupied the city of
Nasa. However, he found the city largely deserted, as much of the population had fled. Those who remained in the city hastily fled as Babatu's troops approached. The Zarma pursued the fleeing population and engaged in another battle near
Wa, in which Babatu's troops again emerged victorious. From here, the Zarma invaded the
Dagarti Land, triggering a general movement of people towards
Wala. However, envoys of the Wala king who went to negotiate with Babatu were murdered by the Zarma. Babatu then had the city of Wa occupied and established his new headquarters there. From Wa, Babatu soon began a campaign into Dagarti Land. However, he only reached Baire (Bayayiri), where the Zarma set up their camp. When attempting to capture the nearby city of Sankana, Babatu army's attack was successfully repelled. Despite the warning of his Mallams, Babatu was determined to continue the war. The Zarma army then moved to Sati and from there to the Kabala Land. The city of Kawulalawuri was occupied during this campaign, but was largely destroyed by the Zarma. However, the Zarma army continued on without staying for long. Unfortunately, nothing else is known about the further course of the campaign. The political result of this Zarma campaign was that the Bona (Boya) residing in the West Gonja area signed a friendship and protection treaty with the British on April 12, 1894. Similarly, on May 4, 1894, the Dagarti signed a similar treaty with the British near Wa, and the Mamprussi signed one in Gambaga on May 28, 1894.
Campaign to the North into Mossi-Land In order to avoid an open confrontation with the British, Babatu turned northward and invaded the
Mossi Empire of
Ouagadougou with his army, even though the
Mossi and Zarma had otherwise remained distant from each other. However, this action had a background: Wobogo, the Moro Naba of Ouagadougou, had previously brought Zarma warriors into the country as
mercenaries to "punish" a "disobedient vassal," the Lalle Naba, with their support. Despite this, due to the onset of the rainy season, the approaching Zarma army was forced to retreat without reaching the capital of the Lalle Naba. Various contemporary witnesses unanimously explain that the Zarma left a deep trail of destruction in their path. This Zarma raid also drove the remaining tribes of the Mossi Empire into the hands of the Europeans. As a result, the Mogho Naba (Mossi Emperor) signed a friendship and protection treaty with the British on July 2, 1894, in Ouagadougou.
Babatu, Samori, and the Europeans As part of the
Heligoland-Zanzibar Treaty negotiations, the governments in
London and
Berlin discussed a possible border between the
British and
German spheres of influence. As a result, the Dagbamba and large parts of
Mamprusi land were divided into British and German spheres of influence, dissolving the Neutral Zone. The north of Mamprusi land was allocated to French territory. The British's strategic goal was to prevent further German and French expansion into the hinterland of the
Ashanti Empire. However, they first needed to quickly eliminate the state structures of warlords like Babatu and
Samori Touré. While the
French and British were arguing over the
Kingdom of Gyaman (west of Ashanti), the Dagbamba began a rebellion that was directed mainly against the Europeans' efforts to gain political dominance in the Dagbon kingdom. Prior to this, the French had already reached the northern borders of
Dagbon and assigned the territory they occupied to the
Upper Senegal and Niger, which was part of
French West Africa, established on June 16, 1895. However, there was no final agreement at that time on the delineation of borders between these areas and the other European colonial powers' spheres of interest. Until then, both Samori and Babatu had avoided any confrontation with the French and had sought to cultivate relationships with the British. This approach initially worked out well for both of them since, as long as they did not pose a threat to the British government based in
Cape Coast, they were left alone. However, this changed with Babatu's campaigns into Mamprusi, Dagarti, and Mossi, and the local authorities' requests for European assistance. But it was Samori's crossing of the Black Volta with his eastern army, under the command of his son
Sarankye-Moré, that alarmed the British the most. In December 1895, Sarankye-Moré's soldiers entered the western Gonja region and left behind widespread destruction and depopulation, as was their custom. The British now felt compelled to act if they did not want to give up their positions north of the Ashanti Empire and leave the areas to the French and Germans. They therefore demanded the withdrawal of Samori's forces, albeit unsuccessfully. At the same time, preparations for a large military expedition aimed to the north were underway. Prior to this, there had been an attempt at reconciliation between Samori and Babatu. Samori proposed an anti-European alliance to Babatu, which also included the Ashanti king and the Gyaman kingdom's leadership. Although the Asantehene signaled his willingness to participate, Braimah, the new Imam of
Bondoukou north od present
Ivory Coast, rejected the proposal despite a generous offer to his person. The Zarma Mallams also threatened to withdraw their support if Babatu accepted Samori's offer. At that time, the Germans were expanding further north to the east of
Dagbon and were actively seeking to win over the Dagbamba king. His kingdom was the most economically powerful central power in the entire region, considering the convergence of crucial caravan routes. This alarmed the British as it posed an immediate threat that the Ashanti Empire's hinterland would be divided by European competition without British involvement. In 1896, the British established a garrison at
Kintampo on the northwest border of the Ashanti heartland, while simultaneously a British military detachment led by
Donald William Stewart marched northeast and occupied Gambaga in Mamprusi land, located northwest of the Dagbamba core area. The British were eager to win over the Dagbamba king to their side, hoping he would conclude a protection and trade treaty with the British Empire. However, the Dagbon anti-European uprising failed, and German troops defeated their army in the
Battle of Adibo on December 4, 1896, occupying the capital,
Yendi, the following day, and destroying much of it in the process. Babatu and Samori now found themselves caught between the European colonial powers and sensed that their downfall was inevitable, especially after the British rejected a negotiation offer from Samori, and the French refused to negotiate with him, having militarily fought against him for years. Samori decided to create political facts of his own and sent negotiators to the
Kong Empire in 1894 to purchase weapons. However, muslim
Dyula merchants, through whom trade in Kong almost exclusively ran, refused the deal due to the ravages of Samorian Sofa gang, which had not spared other Islamic believers on their raids. Kong had already allied itself with the French or did so now, and this amounted to a declaration of war against Samori. As no French military could be seen in Kong, Samori had it occupied. His Sofa gang plundered and looted extensively, capturing and selling a large part of the population into slavery. The once flourishing trading city with its 20,000 inhabitants was reduced to smoking ruins after the massacre, and the Islamic Kingdom of Kong, which had existed since 1710, ceased to exist.
Fall In early 1897, tensions between the British and French over
Bondoukou and the areas surrounding the
Black Volta prompted the British to establish the protectorate of the
Northern Territories of the Gold Coast. This move was intended to prevent the French and Germans from occupying the lands north of Ashanti as they battled against the pirate kings. However, this also meant that Babatu's army was cut off from their route back south. Together with their local allies, the French successfully defeated Babatu and his Zarma army on March 14, 1897, at
Gandiogo. The rest of Babatu's troops were defeated again on June 23, 1897, at
Doucie. The survivors of this battle then fled south, prompting the British to take military action against them in October 1897. The fighting lasted until June 1898, when the last resistance of Babatu's former private army was finally defeated. As the British military presence continued to grow in
Gambaga and other areas east of the
Black Volta, many of the remaining authorities of the Zabarma Emirate in the Gurunsi area fled eastward towards Dagbon. However, eventually, they submitted to British sovereignty. On March 29, 1897, Samori's East Army clashed with the British expeditionary corps commanded by Francis B. Henderson. The battle ended with a crushing defeat of the Samorian army. At this point, the area north of Ashanti and east of the Black Volta was free of slave raiders. However, it's worth noting that the Zabarma Emirate no longer existed as a united entity at that time. ==Ethnic Diversity in the Zabarma Emirate==
