This chapter starts with the origin and a brief history of the application of the thermodynamic laws to (static) black holes and its subsequent generalization to Cosmology. The concepts of the generalized second law of thermodynamics, surface gravity and its connection with Hawking temperature, and Bekenstein entropy are carefully explained. Finally, the implications of the modified and the generalized Hawking temperatures are discussed with reference to the cosmological event horizon.
