Starbursts in H II Galaxies

H II galaxies fall at the lower end on the scale of the energy output of their starbursts. Still, they are genuine Starburst Galaxies, producing large numbers of massive stars, and at a rate which is unsustainable in the long term. In this contribution I discuss the effects of star formation on the interstellar medium in these dwarf galaxies, and review the possibility that interactions are responsible for the onset of the burst.
