The piece was written on the Mozart family's Grand Tour of Europe in London when they had to move to Chelsea during the summer of 1764 due to Mozart's father Leopold's illness (throat infection). The house at 180 Ebury Street, now in the borough of Westminster, where this symphony was written, is marked with a plaque. The symphony was first performed on 21 February 1765. The work shows the influence of several composers, including his father and the sons of Johann Sebastian Bach, especially Johann Christian Bach, an important early symphonist working in London whom Mozart had met during his time there.
