The Battle of Chaldiran was fought between the Ottoman Empire under Selim I and the Safavid Empire under Ismail I. Ottoman use of firearms and artillery proved decisive against the more cavalry-oriented Safavid forces.
Chaldiran is important because it highlighted the growing centrality of gunpowder weapons in early modern warfare and shaped the Ottoman-Safavid frontier for generations. It was a strategic and technological watershed.
