The invasion by which group significantly contributed to the fall of the Old Oyo Empire?

The **Fulani** played a significant role in the fall of the Old Oyo Empire through the series of conflicts known as the Fulani Jihad. The Old Oyo Empire, located in what is now modern-day Nigeria, was one of the largest and most powerful Yoruba-speaking states in West Africa.

During the early 19th century, the Fulani, under the leadership of Usman dan Fodio and his followers, initiated a religious and military campaign known as the Fulani Jihad. This movement primarily aimed at spreading Islam and establishing Islamic states. As the Jihad progressed, it led to increased military pressure and disruptions in regions surrounding the Oyo Empire.

**The Fulani invasions weakened the Oyo Empire in several ways**:

• **Military Pressure**: Continuous attacks and raids weakened Oyo's military strength and resources.
• **Internal Strife**: The invasion contributed to internal unrest, as local leaders and factions vied for power and control amid the crisis.
• **Economic Disruption**: Trade routes were disrupted by conflicts, impacting the economic stability of the empire.

Eventually, the pressure led to the empire's collapse, with the Fulani taking control over many territories that previously belonged to the Old Oyo Empire. Traditional leadership structures also weakened, paving the way for new powers in the region.
