Unilever is a British-Dutch multinational company, originally formed by the merger of the Dutch margarine producer Margarine Unie and the British soap maker Lever Brothers in 1930. Its corporate headquarters have been located in both London, United Kingdom, and Rotterdam, Netherlands, with legal and operational structures spanning these countries. In recent years, Unilever has aimed to simplify its dual structure and maintain its headquarters primarily in Rotterdam while still keeping a significant presence in London. Thus, Unilever is considered an Anglo-Dutch company with strong roots in both the UK and the Netherlands.
