In 1959, Texas real estate developer Angus G. Wynne, Jr. founded the Great Southwest Corporation.
After a ten million dollar investment, the park opened on August 1, 1961. Wynne decided his park would have six areas based on
the governments that have ruled Texas: Spain, France, Mexico, the Republic of Texas, the Confederate States, and The U.S.A. The
park was going to be named Texas Under Six Flags, but Wynne decided Texas should not be under anything and called the park Six Flags Over Texas.
Wynne passed away in 1979, but his legacy continues. Two other Six Flags parks were built, and several other existing parks
were purchased and brought into the Six Flags family in the 1970's. In 1981, Six Flags Theme Parks was incorporated and sold to Bally's a year
later. In 1987, Wesray Capital purchased the chain for $617 million. Time Warner began managing the parks in 1991. In 1998, Premier Parks purchased
Six Flags from Time Warner as well as the rights to use DC Comics and Warner Bros. characters. The Six Flags merged with Cedar Fair in 2024 and now the
Six Flags chain owns 27 amusement parks.
Six Flags Over Texas is home to the world's first log flume ride and the first Mine Train coaster. The 300-foot tall Oil Derrick observation tower opened in
1969. One of the two original Intamin Freefall rides opened here in 1982.
In addition to converting the wood Texas Giant into the steel New Texas Giant, four coasters have left the park:
