On what date was Rolls-Royce Limited registered?

Rolls-Royce Limited was registered on 15 March 1906.

The registration formalised the partnership between Charles Rolls, the wealthy motor dealer, and Henry Royce, the Manchester engineer whose cars had impressed Rolls. The new company began with capital of £60,000. Royce became chief engineer and works director, while Rolls contributed commercial influence and access to an established dealership.

This date is often confused with 11 December 1906, when Rolls-Royce was floated on the Birmingham Stock Exchange to raise additional capital. The company’s Derby factory opened in 1908, marking the next major step in its growth. Rolls-Royce had already begun producing cars under the partnership before the company itself was incorporated, so 1904 is associated with the partnership and early cars, not the registration of Rolls-Royce Limited.
