The Prevention of Terrorism Acts were a series of acts of the Parliament of the United Kingdom from 1974 to 1989 that conferred emergency powers upon police forces where they suspected terrorism.[citation needed]
The direct ancestor of the bill was the Prevention of Violence (Temporary Provisions) Act 1939 which was brought into law in response to an Irish Republican Army (IRA) campaign of violence under the S-Plan. The Prevention of Violence Act was allowed to expire in 1953 and was repealed in 1973 to be reintroduced under the Prevention of Terrorism (Temporary Provisions) Act 1974.
In 2000, the acts were replaced with the more permanent Terrorism Act 2000, which contained many of their powers, and then the Prevention of Terrorism Act 2005. See also Terrorism (Northern Ireland) Act 2006.
