The Illuminations were first shown in 1879 when they were described as 'Artificial sunshine', and consisted of just eight carbon arc lamps which bathed the Promenade. The original event preceded Thomas Edison's patent of the electric light bulb by twelve months. The first display similar to the modern-day displays was held in May 1912 to mark the first British Royal family visit to Blackpool when Princess Louise opened a new section of the Promenade, Princess Parade. The Promenade was decorated with what was described as "festoons of garland lamps" using about 10,000 light bulbs. The local Chamber of trade as well as other local businesses requested Blackpool Council to stage the event in September of the same year. The subsequent event was such a success that in 1913 the council were again asked to stage the Princess Parade lights as an end of season event. With the outbreak of the First World War there were no further displays until 1925 when the lights were again on display and extended to run from Manchester Square to Cocker Square. In 1932 animated tableaux were erected running along the cliffs from North Shore to Bispham, and the Illuminations were extended to its current length running from Starr Gate to Red Bank Road at Bispham.
