Cunhambebe vs Mahmud I of Great Seljuk

Cunhambebe became the principal leader of the Tupinamba people in the region of Rio de Janeiro, organizing resistance against Portuguese colonization. He led attacks on Portuguese settlements and allied with the French to oppose Portuguese expansion.

Cunhambebe formed an alliance with French traders and colonists, including Nicolas Durand de Villegagnon, who established the France Antarctique colony. The alliance provided the Tupinamba with firearms and support against the Portuguese.

Cunhambebe led Tupinamba warriors in a major attack on the Portuguese settlement of Rio de Janeiro, which had been founded by Est

Cunhambebe died, possibly from wounds or disease, during the ongoing conflict with the Portuguese. His death weakened the Tupinamba resistance, and his successor continued the struggle but with less success.

Following the death of his father Malik Shah I, Mahmud I was proclaimed sultan at age five. His mother Terken Khatun acted as regent, but the succession was contested by his half-brothers Barkiyaruq and others, leading to civil war.

Forces loyal to Mahmud I, led by his mother Terken Khatun and general Kerbogha, fought against Barkiyaruq's army near Al-Ruhaymi in Iraq. Mahmud's forces were defeated, weakening his claim to the sultanate.

Mahmud I died at age seven, likely from illness. His death ended his brief reign and allowed Barkiyaruq to consolidate power as the sole Seljuk sultan, though the empire remained divided by ongoing succession conflicts.
