National Westminster Bank

Both predecessor banks were early English joint-stock banks formed after reforms of the 1820s and 1830s loosened the Bank of England's monopoly.

National Westminster Bank was created in 1968 by combining National Provincial Bank (founded 1833) and Westminster Bank (founded 1834 as London and Westminster Bank), with District Bank also folded in. It became one of the UK's big clearing banks and was acquired by the Royal Bank of Scotland in 2000. Its brand now gives the whole group its name. (Exact birth year remains publicly undisclosed).
