Editing Grayson County, Texas (section)

===20th century to present===
During the [[Sherman Riot of 1930]] (May 9, 1930),<ref>[https://tshaonline.org/handbook/online/articles/jcs06 Handbook of Texas Online, s.v. "Sherman Riot of 1930"] (accessed March 6, 2007)</ref> Grayson County's 1876 courthouse was burned down by a white mob that rioted during the trial of George Hughes, an [[African Americans|African-American]] man. When the riot started, Hughes was locked by police in the vault at the courthouse, and died in the fire. After rioters retrieved Hughes' body from the vault, they dragged it behind a car, hanged it, and set afire. Texas Ranger [[Frank Hamer]] was in Grayson County during this riot, and reported the situation to [[Governor of Texas|Texas Governor]] [[Dan Moody]].<ref>{{Cite web|url=http://www.tsl.state.tx.us/governors/personality/moody-hamer-1.html|title=Statement from Frank Hamer, May 13, 1930 {{!}} TSLAC|website=www.tsl.state.tx.us|language=en|access-date=July 24, 2018}}</ref> Governor Moody sent [[National Guard (United States)|National Guard]] troops to Grayson County on May 9 and more on May 10 to control the situation. Grayson County's current courthouse was completed in 1936.

The Bridge War, also called the [[Red River Bridge War]] or the Toll Bridge War, was a 1931 bloodless boundary conflict between the U.S. states of [[Oklahoma]] and Texas over an existing [[toll bridge]] and a new free bridge crossing the Red River between Grayson County, Texas, and [[Bryan County, Oklahoma]].

In 1938, construction of a [[dam]] on the Red River was authorized by the [[United States Congress]]. The dam's construction was completed in part by the use of labor provided by [[Germans|German]] [[prisoners-of-war]] held at [[Camp Howze, Texas|Camp Howze]],<ref>{{Cite web|url=https://tshaonline.org/handbook/online/articles/qug01|title=GERMAN PRISONERS OF WAR|last=P.|first=KRAMMER, ARNOLD|date=June 15, 2010|website=www.tshaonline.org|language=en|access-date=July 24, 2018}}</ref> in adjacent [[Cooke County, Texas|Cooke County]] during [[World War II]]. The dam is now known as [[Denison Dam]]. [[Lake Texoma]] was formed behind it and is used for recreation, irrigation, and electrical power generation.

[[Perrin Air Force Base]] was constructed in 1941. The base closure in 1971 was a blow to the county economy; however, the availability of skilled labor formerly associated with the base helped attract industrial plants. In addition, the base was converted to a civilian airport: [[North Texas Regional Airport]] - Perrin Field.

The [[Eisenhower Birthplace State Historic Site]], which is the birthplace of [[Dwight D. Eisenhower]] in Denison, was acquired and restored in 1952. Since 1993, the site is no longer maintained by the state, because of budget cuts, but it is maintained by a private nonprofit organization.<ref>{{Cite web|url=https://tshaonline.org/handbook/online/articles/ghe01|title=EISENHOWER BIRTHPLACE STATE HISTORICAL SITE|last=BRIAN|first=HART|date=June 12, 2010|website=www.tshaonline.org|language=en|access-date=July 24, 2018}}</ref>
