A ministry (usually preceded by the definite article, i.e., the ministry) refers to a collective body of government ministers headed by a prime minister or premier. Although the term "cabinet" can in some circumstances be a synonym, a ministry can be a broader concept which might include office-holders that do not participate in cabinet meetings. Other titles can include "administration" or "government" to describe similar collectives in a parliamentary system.
As head of the collective ministry, from 1911 to 1933, the official title of the prime minister of Portugal was that of President of the Ministry (Portuguese Presidente do Ministério).
