Can fire occur from a non-oxygenated reaction?

Combustion is the reaction of a material with oxygen, right? But the fire is a result of the energy being released from the exothermic reaction. So does that mean that other exothermic reactions can create fire? Or is it just oxygen, and why?

It probably depends who you talk to as to how specifically they'd define it.  But certainly there are other chemicals that burn exothermically - for example anything that can burn with oxygen can burn with fluorine.  Even after it's been burned with oxygen.
