Westminster diocese was dissolved in 1550, but the abbey was recognised (in 1552, retroactively to 1550) as a second cathedral of the Diocese of London until 1556. The already-old expression "robbing Peter to pay Paul" may have been given a new lease of life when money meant for the abbey, which is dedicated to Saint Peter, was diverted to the treasury of St Paul's Cathedral.
The abbey was restored to the Benedictines under the Catholic Mary I of England, but they were again ejected under Elizabeth I in 1559. In 1560, Elizabeth re-established Westminster as a "Royal Peculiar" – a church responsible directly to the Sovereign, rather than to a diocesan bishop – and made it the Collegiate Church of St Peter (that is, a church with an attached chapter of canons, headed by a dean.) The last of Mary's abbots was made the first dean.

It suffered damage during the turbulent 1640s, when it was attacked by Puritan iconoclasts, but was again protected by its close ties to the state during the Commonwealth period. Oliver Cromwell was given an elaborate funeral there in 1658, only to be disinterred in January 1661 and posthumously hanged from a gibbet at Tyburn.
