An inauguration is a ceremony of formal investiture whereby an individual assumes an office or position of authority. The term is usually used in reference to a politician's assumption of the duties of head of state or head of government (e.g. "the President's inauguration").
Political inaugurations often have lavish ceremonies, in which the politician publicly takes his or her oath of office in front of a large crowd of spectators.

Note
It remains unclear whether the decision of Popes John Paul I and John Paul II to opt for the simplified Papal Installation as a form of inauguration rather than a traditional Papal Coronation has set a precedent to be followed, or whether the successor to Pope John Paul II will return to the traditional coronation favoured by past popes for over one millennium.
