1911 Formed Automobiles Rolls-Royce (France) Limited. 
WWI The company was concerned that the outbreak of war would curtail demand for their luxury automobiles but they did not plan to make aero-engines. However, after a request from the Royal Aircraft Factory, they did tender to build some Renault aero-engines. Unimpressed by the design of these engines, Royce was inspired to design his own aero-engine, which became the Eagle, a V12 engine that went on to be used in a number of military aircraft.
In order to keep up with demand once the Eagle was established, the War Office tried to persuade the company to allow other UK manufacturers to contribute production resources but the company resisted this. Instead there was a big expansion of the Derby factory but Brazil, Straker and Co were also allowed to build Eagles and the smaller Falcon engine; Brazils also built the 6-cylinder variant, the Hawk.
1919 Established a factory in America
1921 The company opened a second factory in Springfield, Massachusetts.

WWII Opened a new factory at Hillington near Glasgow to make components for aero-engines and eventually complete engines, supplementing production at Derby and Crewe.
As well as producing key aero-engines such as the Merlin, Rolls-Royce took over production of the Whittle jet engine from Rover.
1961 Parent of 13 subsidiaries. Group employs 44,000 persons. Manufacturers of motor car, aero engines, petrol and oil engines, rocket motors and nuclear propulsion. Specialists in designing, developing and procuring of nuclear compartments for naval vessels. 
1968 Queen's Award to Industry for Export Achievement. 
1971 Financial problems caused largely by development of the new RB 211 turbofan engine led — after several cash subsidies — to the company being nationalised by the Heath government in 1971. (Delay in production of the RB211 engine has been blamed for the failure of the technically advanced Lockheed TriStar, which was beaten to launch by its chief competitor, the Douglas DC-10.)
1971 The receiver created a new company, Rolls-Royce Motors, to contain the profitable parts of the company including the car manufacturing division, the marine and industrial diesel engines, military vehicle operations and rights to the Wankel engine. The new company included the coach building businesses of H. J. Mulliner, Park Ward and Bentley Motors (1931). The gas turbine businesses were put into a new company Rolls-Royce (1971) Ltd
1973 Having failed to attract sufficiently high offers in the sale by tender, the automobile business was spun off as a public company, Rolls-Royce Motors Ltd. The main business of aircraft and marine engines remained in public ownership until 1987, when it was privatised as Rolls-Royce plc, one of many privatisations of the Thatcher government.
