The belief in one GoD. ChristianIty, JudaIsm and IsLam are three famous examples of monotheistic religions. Note that the one GoD may have several aspects, such as the concept of the HolyTrinity in ChristianIty. Monotheistic religions have a tendancy to have strict sets of moral codes or laws (as they have a DivineLawgiver to provide them and justify them), often have a bias to one gender (due to the supposed gender of the GoD in question), and appear to have become more prevelant later in civilisations, when order is a GoodThing and explanations for random natural disasters are beginning to come from other sources than angry GoD''''''s.
