At the Versailles Peace Conference of 1919, British historian and politician Lewis Bernstein Namier, who served as part of the British delegation, was seen as one of the biggest enemies of the newly independent Polish state in the British political sphere and in the newly-independent Poland. Namier modified the previously-proposed Curzon line by detaching the city of Lwów from Poland with a version called Curzon Line "A". It was sent to Soviet diplomatic representatives for acceptance. The earlier compromised version of Curzon line which was debated at the Spa Conference of 1920 was renamed Curzon Line "B".
