Abstract: 
Black holes appear spontaneously during the inflationary era through
quantum pair creation. The instantons responsible for this process are
presented and the pair creation rate is calculated semi-classically.
This analysis has implications both for the boundary conditions and
for the global structure of the universe.  The black holes thus
created are ideal for the study of black hole physics, since their
evolution depends non-trivially both on classical and quantum
effects. The cases of neutral and charged black holes are investigated
separately, because their evolution is qualitatively different. The 
inclusion of a dilaton field leads to some highly unusual features.
