History
Seagoville was originally called Seago, and under this name was laid out in 1876 by T. K. Seago (1836–1904), and named after him. The United States Post Office changed the town's name to "Seagoville" in 1910 to prevent confusion with another city in Texas called Sego.
During World War II, the Federal Reformatory for Women in Seagoville was the site of an Immigration and Naturalization Service detention camp for Japanese, German, and Italian Americans classified as "enemy aliens" and women of Japanese and German ancestry deported from Latin America. Internees at Seagoville published a German language newsletter called the Sägedorfer Fliegende Blätter. The camp housed up to 647 people, and was closed in June 1945, after the internees were either "repatriated" to Japan or Germany, or transferred to Crystal City, Texas.

The United States Postal Service operates the Seagoville Post Office on Seagoville Road in Kleberg, Dallas. It was previously located at 314 Glendale Avenue, in a rented facility in Seagoville. Since around 1882 a post office had been located in the Seagoville city limits. In 2011, the USPS announced that it was closing the existing Seagoville post office and consolidating it into the Kleberg Post Office, a USPS-owned facility since renamed to the Seagoville Post Office, citing cost-cutting reasons in response to a budget shortfall. Though individuals had offered to pay for the rental costs at Seagoville, the USPS insisted on closing the city post office. As of 2011, the Seagoville city post office was busier than the Kleberg one.

=History of schools=
The first school established in Seagoville was the Brinegar School. The one-room log schoolhouse, which featured split-log seating, was constructed around 1867 in the area of the modern-day Heard Park. Professor J.T. Doss built a new school building in 1880; it was called Woodside. Another school opened in a four-frame building. A cyclone destroyed one of its rooms in 1903, and in 1909 that school was destroyed in a fire. In 1910 a new brick high school building opened on the site of what is now Seagoville Elementary School. The building, a two-story facility with four rooms for upper grades upstairs and four rooms for lower grades downstairs, on land on North Kaufman Street was donated by Ben H. Fly. It was built for about $10,000 ($283,000 adjusted for inflation to 2022), and was known as "The High School" and "the Old Red Schoolhouse".
Seagoville High School first opened in 1928 on land purchased in 1927. This high school building later burned down, and Central Elementary School opened on the former high-school site. The current high school facility and Seagoville Middle School opened on a plot of land donated by M.D. Reeves in 1952: one building opened in 1955 and the other opened in September 1958. Seagoville was in the Seagoville Independent School District until August 1964, when it merged into DISD.
