Probably gasoline.
One of the first propellants used for rockets was gunpowder, which dates back to ancient China. Gunpowder, a mixture of sulfur, charcoal, and potassium nitrate, provided the explosive force needed to propel early rockets.
To get an even burn through the full length of the propellant. Also, burning from the inside out keeps the propellant tube from overheating. A crack in the propellant would cause a burn to the tube wall and rupture before all the propellant is consumed.
