D−
HistoryA character grade: shown, never part of Surprise’s overall grade.
Among the 400 U.S. cities of 100,000 or more, Surprise ranks #387 on History.
Few Arizona towns list much on the Register (a typical Arizona town has 0.1 per 10,000 residents, the U.S. 2.4), so Surprise’s 0.0 sits below most of its state (29% of Arizona towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.
Newer cities are common at Surprise’s size: in the typical U.S. city of 100,000 or more, 5% of homes predate 1940.

What stands out about Surprise’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
The city was founded in 1938 by Flora Mae Statler, who was the daughter of another Arizona pioneer, Charles Gillett, who helped found Glendale, specifically as a temperance community. Gillett owned much land in Glendale, as well as the Verde Valley. Surprise officials previously thought the city was founded by Statler's husband, real estate developer and state legislator Homer C. Ludden, but in 2010, property records were discovered that listed Statler as owning the land before she met Ludden. Modern records often state that Statler named her land Surprise as she "would be surprised if the town ever amounted to much," with her daughter backing this claim. This claim is contested, however, since pioneers commonly named their settlements after their hometowns and Ludden hailed from Surprise, Nebraska, possibly influencing the name of the town.
In 1937, according to Wikidata. Surprise’s post office opened in 1892, and the census of 1970 counted 2,427 people here.
