About this source

What it is

The Sidi Yahya Mosque is a mosque and madrasa in Timbuktu, Mali, with construction beginning around 1400 and finishing around 1440. It was named after its first imam, Sidi Yahya al-Tadelsi, and is associated with Timbuktu's historic community of scholars alongside the Djinguereber and Sankoré mosques.

Why it matters

This mosque belonged to the same Timbuktu scholarly establishment that clashed with Sonni Ali after he captured the city in 1469. The scholars connected to mosques like this one later wrote the chronicles, such as the Tarikh al-Sudan, that shaped Sonni Ali's harsh historical reputation. The mosque shows the depth and age of the learning community whose judgment of him has lasted for centuries.

Look closer

  • Why would the scholars of mosques like this one have a strong opinion about a conquering ruler like Sonni Ali?
  • What does the long history of this mosque tell us about Timbuktu's role as a center of learning?
  • How might buildings like this help explain why written history can be biased against certain rulers?
